Abstract:
The Government Agency like Municipal Corporation must issue the notices to such buildings/ structures which are having age more than 30 years. Mostly the maintenance is ignored in many structures which may cause some severe problems. Health and performance of buildings also depends on the maintenance of structure which plays a great role. Thus, Structural Audit of such type of buildings is necessary and timely maintenance /repairs also important. This will lead to prolonged life of building and safety of occupants. It also emphasizes on different repairs and retrofitting measures to be used for buildings after structural audit. Structural Audit is an overall health (strength assessment) and performance checkup of a building. It analyzes the strength and then suggests repair and retrofitting for the building to improve the service life of the structure. Enhance the life of the building by suggesting some preventive repairs. An old building with more than 15 years should be selected for structural Audit. And then the test should be performed on structure. Keywords- Structural Audit, Strength assessment, NDT, UPV Test, Rebound Hammer Test

Abstract:
The sequential ground motion effects on the dynamic responses of reinforced concrete containment (RCC) buildings with typical isolators are studied in this paper. Although the base isolation technique is developed to guarantee the security and integrity of RCC buildings under single earthquakes, seismic behavior of base-isolated RCC buildings under sequential ground motions is deficient. Hence, an ensemble of as-recorded sequential ground motions is employed to study the effect of including aftershocks on the seismic evaluation of base-isolated RCC buildings. The results indicate that base isolation can significantly attenuate the earthquake shaking of the RCC building under not only single earthquakes but also seismic sequences. It is also found that the adverse aftershock effect on the RCC can be reduced due to the base isolation applied to the RCC. More importantly, the study indicates that disregarding aftershocks can induce significant underestimation of the isolator displacement for base-isolated RCC buildings.

Abstract: Modern tall buildings have efficient structural systems, and utilize high-strength materials, resulting in reduced building height, and thus, become slenderer and more flexible with low damping. These flexible buildings are very sensitive to wind excitation and earthquake load causing discomfort to the building occupants. Therefore, in order to mitigate such an excitation and to improve the performance of tall buildings against wind loads and earthquake loads, the tube in tube structures and tube frame structures are the innovative and fresh concept in the tubular structures. Generally, tube in tube structures is formed by connecting peripheral frame tube and inner core tube so closely, it is not seen as a solid system but it acts like a solid surface. The total loads acting on the structures to be collectively shared between the inner and outer tubes. The tubed frames Structure are new concept for tall building. In tubed mega frames instead of one central tube several vertical tubes are carrying the lateral loads. a comparative study of tube in tube structures and tubed mega frame system with different building geometry has been done using ETABS software.

Abstract:
India has been facing many disasters since long. Among the entire disasters earthquake is of serious concern to Civil Engineers. Because of collapse of structures subjected to seismic loads many lives were lost because these buildings were not designed for seismic loads. The problem becomes more serious when additional storeys are constructed. In these buildings many of the columns are not safe if the building is analyzed for seismic load. To make the building safe we need to adopt the technique of FRP (Fiber Reinforced Polymer) jacketing. The FRP Jacketing is comparatively better than other retrofitting because no major strengthening of foundation is required in this technique, also original function of the building can be maintained without any major change in the original geometry of the building. The present study is on a four storey building that has been planned in STAAD.ProV8i, considering M30 cement and Fe415 steel bars.

Abstract:
Abstract High rise structures becoming very common everywhere due to scarcity of land and increasing population. Though we have RCC structure system as high-rise buildings, but in RCC buildings due to bulky size of the components of the structure self-weight will be more due to the heavy density of materials. By observing the difficulties and challenges in the field of high-rise structures engineers are using efficient structural system that is Steel Concrete Composite Structure. Composite structure consists composite deck slab, composite beam and composite column. Composite Structure complies of Concrete which is good in compression and structural steel which good in tension and composition of these material makes structure better in ductility which comparatively on higher side than RCC structure. Here G+7 high rise structure is considered for analysis by ETABS software. This paper involves Analysis of Commercial building by Equivalent static method on Composite structure and RCC structure with same plan of building and same design data. The structure is in earthquake zone III and wind speed 44m/s. Analytical comparisons of both Composite and RCC frame based on structural parameters are made with help of graphs and tables. By comparing the results, we found that Steel-Concrete Composite Structures are more desirable than RCC structures.

Abstract The earthquake is the most devastating and unexpected natural phenomenon, causing massive damage to both human lives and infrastructure. In this study, two different irregulars Reinforced Cement Concrete (RCC) building plans of 25th story buildings with the ground floor (G+25) and 9th storey buildings with the ground floor (G+9) were subjected to four different zones making a total of eight model structures to test their ability to withstand gravity and seismic loads. The design was response spectrum method (RSM) then subjected to an earthquake load in accordance with Indian Standard (IS) 1893. The earthquake performance is evaluated on the basis of the structure’s design, serviceability, and earthquake power using an extended three-dimensional analysis of building systems (ETABS). The behaviour of building irregularities under seismic loading is investigated in this work. In this study, it has been compared the results in terms of max story displacement, max story drifts, and base shear. It was found that the model in zone 5 has maximum story displacements among all other models as well as higher max story drifts and base shears for both plans of G+9 and G+25. From the result, it was concluded that both the building models in the lower zone showed better performance in terms of max story displacement, max story drift, and base shear.

Abstract:
Progressive collapse starts when any load-carrying elements of the building collapse during extreme loading, such as earthquakes, blasts, or fire. The Precast Steel Reinforced Concrete (PSRC) buildings comprise of precast RCC columns and steel girders. These structural elements are connected to form a moment-resisting frame and are susceptible to progressive collapse. However, this structural system has the advantage of inherent stiffness and damping during lateral loads and is also known for its construction efficiency, lightweight and low cost. Earlier investigations have shown PSRC systems useful in designing and constructing buildings while maintaining ample strength and high ductility during seismic incidents. Despite much previous research, the PSRC structural system's use is limited in high seismic regions. This paper aims to study the progressive collapse of the PSRC building using non-linear dynamic analysis and U.S. General Service Administration (GSA) guidelines during extreme loading. Two structures are studied to validate the performance of progressive collapse of PSRC and RCC structures. Four-story PSRC and RCC buildings are designed according to Indian Codes of practice. Design columns under provisions of the Indian reinforced concrete structures code, and beams are designed according to the Indian steel construction code. Comparative studies of progressive collapse for the two buildings are presented.

Abstract:
A Construção Civil é um dos setores que mais consomem matérias-primas e também gera resíduos sólidos urbanos. É importante, que se consuma menos matérias-primas e que sejam aproveitados estes resíduos gerados. Uma das propostas para esta situação seria reciclar estes resíduos e transformá-los em agregados e filers, para então usá-los na produção de concretos. Ainda se encontram muitas barreiras para utilização destes agregados e filers em concretos, com e sem função estrutural e, dentre os principais motivos está a dificuldade de se alcançar resistências similares as dos concretos produzidos com matérias-primas naturais. Devido a este fato, foi proposto um estudo para analisar a influência do empacotamento de partículas nos agregados reciclados e ainda verificar a possibilidade de uso do filer de pó do polimento das placas de concreto para revestimento de piso. Inicialmente foram caracterizados dois lotes de agregados reciclados e apenas o de resíduo de concreto (ARC) foi considerado adequado para o estudo. Foram propostos três planejamentos experimentais compostos por mistura simplex com 4 fatores das misturas, contendo além dos agregados, filer e cimento Portland CP-V. Foram realizados estudos sobre as massas unitárias das amostras, para cada um dos planejamentos, considerando toda a faixa granulométrica, e também, amostras sem o material passante pela peneira com abertura de 0,150 mm. A quantidade de água foi determinada pelo consistômetro de Vebe, e a partir deste dado foi calculado o excesso de pasta. Após a obtenção dos corpos de prova, sob vibrocompactação, foi determinado o comportamento da resistência mecânica e da absorção de água. A análise dos resultados mostrou que o melhor empacotamento de partículas dos agregados ocorre na faixa de 42% a 58% de pedrisco. O filer utilizado em grandes quantidades, aumenta significativamente o consumo de água de amassamento e o de excesso de pasta, e por consequência, o aumento da absorção de água e perda de resistência do concreto seco. Entretanto, em quantidades menores que o volume de poros, a inclusão do filer é aceitável, pois não há afastamento das partículas. Conclui-se que, na faixa granulométrica estudada não houve alteração de resistência mecânica, sendo o fator preponderante a concentração de cimento. As resistências à compressão observadas mostram que estes agregados podem ser utilizados na fabricação de artefatos de concreto, como por exemplo, produção de blocos de vedação.
Civil Construction is one of the sectors that consumes the rawest materials and also generates municipal solid waste. It is important that less raw materials are consumed and that waste generated is used. One of the proposals for this situation would be to recycle these wastes and turn them into aggregates and filers and then use them in the production of concrete. There are still many barriers to the use of these aggregates and filers in concrete, with and without structural function, and among the main reasons is the difficulty of achieving similar resistance to concrete produced with natural raw materials. Due to this fact, a study was proposed to analyze the influence of the packing of particles in the recycled aggregates and to verify the possibility of using the filter of powder of the polishing of the concrete plates for floor covering. Initially, two batches of recycled aggregates were characterized and only that of concrete residue was considered adequate for the study. Three experimental schedules were proposed, composed of 4 factors of the mixtures, plus the aggregates, filer and Portland cement CP-V. Samples were analyzed for the sample masses, considering the entire grain size range, as well as samples without material passing through the sieve with a 0.150 mm opening. The amount of water was determined by the Vebe consist meter, and from this data, the excess paste was calculated. After the test specimens were obtained, under vibrarocompaction, the behavior of the mechanical resistance and the water absorption were determined. The analysis of the results showed that the best packaging of particles of the aggregates occurs in the range of 42% to 58% of hail. The filer used in large quantities significantly increases the consumption of kneading water and excess paste, and consequently, increased water absorption and loss of strength of dry concrete. However, in smaller amounts than the pore volume, the inclusion of the filer is acceptable, since there is no separation of the particles. It was concluded that in the granulometric range studied, there was no change in mechanical strength, being the preponderant factor the concentration of cement. The observed compressive strengths show that these aggregates can be used in the manufacture of concrete artifacts, such as the production of sealing blocks.

Abstract:
The aim of this research study is to investigate the vulnerability of the building heritage in Gorizia, a town in north-eastern Italy, on the border with Slovenia. This town has not been considered seismic until the year 2003 and then in 2010 it has been classified in a higher seismicity class. For this reason, most of the buildings are not designed to resist seismic action at all and an even lower percentage fulfils the requirements of the current technical standard. Four real existing buildings are analysed as case study buildings, representative of the main structural types that can be found in the town. Two of them are high - rise (11 and 12 storeys) reinforced concrete (RC) framed buildings with a brittle concrete stairwell, designed for gravitational load only and built in the 60’s-70’s. In the last years, a growing attention has been payed to the seismic vulnerability of existing RC framed structures, but this type of buildings, with a core of concrete walls, has been investigated much less, although it is a structural type that is very spread. The other two case studies are masonry buildings built in 1740 and in 1903, respectively. One of the masonry buildings is the city hall of Gorizia, on which many in-situ tests have been performed within a project of the Department of Engineering and Architecture with the Municipality of Gorizia. For both RC buildings, some considerations are made about the influence of the masonry infills on the seismic behaviour of the building and of the numerical model. The vibration periods found with numerical modelling are also compared to the periods evaluated with vibrational measurements. The two numerical models without infills are then analysed with non-linear static and dynamic analyses. The results are processed with a cloud analysis in order to calculate fragility curves of the buildings, that show a very brittle behaviour. The two masonry buildings are analysed also with pushover analysis. For the evaluation of the seismic vulnerability of the analysed buildings, two types of seismic hazard assessments have been considered for the extraction of the seismic inputs: Probabilistic Seismic Hazard Assessment (PSHA) method, by the Italian code response spectra and Neo Deterministic Seismic Hazard Assessment (NDSHA) method, with response spectra of two specific possible scenarios for the town of Gorizia. The physics-based scenarios are calculated for the two faults that are the closest to Gorizia: Idrija and Medea. A comparison is made between the demand given by the seismic inputs defined with the two methods. The importance of using both methods for the design of low-damage retrofitting solutions is highlighted. At last, a theoretical study has been carried out within the present research study in order to find an innovative and effective solution for the retrofit of the RC high-rise brittle buildings. It consists in the application of an exo - or endo - skeleton, with the additional introduction of a sliding system at the base of the RC building, in order to decouple its motion from the ground motion. In this way, the exo- or endo-skeleton can be designed independently from the features of the existing building, that remains undamaged. The characteristics of the exo/endo-skeleton can be calibrated on the seismic input of the site of interest, with the possibility to adapt it to new seismic classifications of the territory.

Abstract:
Solitamente le tamponature vengono trascurate nella modellazione delle strutture a telaio in cemento armato e solamente il loro contributo in termini di massa viene preso in considerazione, assumendo che la resistenza e la rigidezza delle stesse non influiscano sulla risposta strutturale. Questa pratica è supportata dal fatto che (i) generalmente allo stato limite ultimo le tamponature si considerano completamente danneggiate e, quindi, il loro contributo in termini di rigidezza è trascurabile, mentre (ii) allo stato limite di danno il valore dello spostamento di interpiano, ottenuto trascurando il contributo di rigidezza delle tamponature, può essere considerato a favore di sicurezza. Tuttavia, per edifici di importanza strategica, quali scuole, ospedali, caserme delle forze dell’ordine e dei Vigili del Fuoco, è cruciale preservare le tamponature da qualsiasi danno, anche per terremoti di entità severa, in modo da garantire il normale utilizzo dell’edificio durante la gestione dell’emergenza. Inoltre, questi edifici a volte sono sismicamente protetti con sistemi e dispositivi (smorzatori, isolatori, ecc…) il cui progetto richiede che sia tenuto in considerazione il reale comportamento dinamico della struttura (in termini di frequenze e/o spostamenti e/o velocità). Per questo diventa cruciale modellare accuratamente l’intera struttura, includendo le tamponature, e validare questo modello così ottenuto sulla base dell’evidenza sperimentale. La tipologia delle pareti e le loro procedure costruttive sono fonte di incertezze nella modellazione delle interazioni tra la struttura e gli elementi non strutturali. Quindi, una valutazione sperimentale delle proprietà di rigidezza dei pannelli di tamponatura potrebbe essere molto utile per valutare, all’interno del modello strutturale adottato per il progetto, il contributo in termini di rigidezza fornito alla struttura in c.a. da questi elementi non strutturali. In questa tesi viene presentata una procedura per realizzare modelli globali agli elementi finiti accurati di edifici a telaio in c.a. tamponati, basandosi su risultati ottenuti da analisi modali sperimentali e operative sviluppate rispettivamente su elementi non strutturali e sull’intero edificio. In particolare, sono stati eseguiti test di impatto con martello strumentato su pareti omogenee per identificarne i parametri modali (frequenze e forme modali) e per stimarne le proprietà meccaniche. Dopo di che, le tamponature sono state inserite nel modello strutturale globale agli elementi finiti, i cui parametri modali vengono confrontati con quelli derivanti da analisi modali operative basate su misurazioni di vibrazioni ambientali per valutarne l’accuratezza. In seguito, è stata condotta una campagna sperimentale su tre provini di tamponatura costruiti all’interno del Laboratorio di Prove di Materiali e Strutture della Facoltà di Ingegneria dell’Università Politecnica delle Marche. Questi provini sono stati realizzati con l’intento di riprodurre le caratteristiche di alcune delle tamponature testate in sito e su di essi vengono svolte prove sia dinamiche che statiche. Innanzi tutto, sono stati effettuati test ad impatto con martello strumentato per investigarne il comportamento dinamico fuori dal piano; successivamente sono state svolte prove di spinta laterale per investigare il comportamento statico nel piano dei pannelli soggetti a bassi livelli di forze orizzontali. I risultati sperimentali ottenuti sono stati utilizzati per calibrare modelli agli elementi finiti dei provini al fine di valutare l’esattezza delle proprietà meccaniche delle tamponature stimate in precedenza e secondo diversi approcci.
Infill walls are commonly disregarded in the modelling of reinforced concrete (r.c.) frame structures and only their contribution in terms of mass is taken into account assuming that resistance and stiffness do not affect the structural response. This practice is supported by the fact that (i) at ultimate limit state infill walls are usually considered to be completely damaged, so that their contribution is negligible in terms of stiffness, while (ii) at the damage limitation limit state the value of the interstorey drift, obtained by neglecting the infill walls stiffness contribution, is commonly considered to be conservative. However, for strategic buildings, such as schools, hospitals, police and fire stations, it is crucial to preserve the infill walls from any damage, even for severe earthquake, in order to guarantee the building occupancy during the emergency management. Furthermore, these buildings are sometimes seismically protected with system and devices (dampers, isolators, etc…) whose design requires the real dynamic behaviour of the structure (in terms of frequencies and/or displacements and/or velocities) to be considered. To this purpose, it becomes crucial to accurately model the entire structure, including infill walls, and to validate this model on the basis of experimental evidences. The wall typology and the construction procedures are source of uncertainties in modelling interactions between structural and non-structural components. Thus, an experimental evaluation of the stiffness properties of the wall infill panel could be very useful to assess the stiffening contribution added by the infill masonry walls to the concrete frame in the structural model adopted for the design. In this thesis is presented a procedure for developing accurate global finite element (f.e.) models of infilled r.c. frame buildings based on results of experimental an operational modal analysis of non-structural components and of the whole buildings. In particular, impact load tests with an instrumented hammer are performed on homogeneous wall panels to identify the modal parameters (frequency and mode shapes) and to estimate the mechanical properties of the masonry walls. Afterwards, the infill walls are included in the f.e. structural model, whose modal parameters are compared with those derived with operational modal analysis based on ambient vibration measurements. Furthermore, an experimental campaign on three specimens of infill masonry walls built in the Laboratory of Materials and Structures of the Faculty of Engineering at the Università Politecnica delle Marche is conducted. These specimens are built with the target to reproduce the features of some of the in situ investigated infill walls and are tested both dynamically and statically. First of all, impact load tests with an instrumented hammer are performed to investigate the out of plane dynamic behaviour of these walls; then, lateral load tests are carried out to investigate the in plane static behaviour of the panel under low level of lateral forces. The experimental results obtained are used to calibrate f.e. models of the specimens with the aim to evaluate the reliability of the masonry mechanical properties estimated through different approaches.

Abstract:
Apesar de ser uma grande geradora de impactos ambientais devido ao grande consumo de matéria-prima e da grande geração de resíduos, a Construção Civil é reconhecida como uma das mais importantes atividades para o desenvolvimento econômico e social do país. Nos países desenvolvidos, a geração de RCD nas obras de demolição entre os anos de 1994 a 1999 variava entre 32 e 99 ton/ano. O que não difere muito do Brasil, que em 2005, através de pesquisas em 11 Municípios, observou-se uma geração de resíduos com média de 59% também, provenientes de obras de reforma, ampliação e demolição. O Município de Petrolina localizado em pleno sertão Pernambucano, atualmente, tem uma população de 268.339 habitantes e ainda não possui um sistema de gerenciamento de RCD, conforme preceitua a Resolução n. 307 do CONAMA (2002). Visando contribuir com o estudo desta problemática, a presente dissertação realiza um diagnóstico dos RCD do Município verificando sua potencialidade de reciclabilidade. A pesquisa constitui de um trabalho de campo de natureza exploratória e descritiva que visa identificar os materiais descartados pela indústria da construção civil de 10(dez) empresas geradoras de RCD, bem como identificar, para efeito de estudos de impacto ambiental, 11(onze) pontos de deposição irregular de RCD e a possível reutilização desses materiais. Os resultados demonstraram que 91,2% dos materiais são resíduos classe A, com potencial de reciclabilidade, tendo em vista os descartes de materiais cerâmicos representar no total da amostra 45,5% de todo o material observado, seguido de argamassas com (23,6%), de concreto (14,1%) e da areia (8,0%), ficando os 8,8% restantes destinados ao descartes de plásticos, gesso e madeira. Apesar da falta de uma destinação adequada, tanto as empresas quanto o Poder Público do referido município, tentam se adequar ao que determina a Resolução 307, em especial, no que se refere ao beneficiamento dos RCD, implantando uma usina de reciclagem no aterro remediado Raso da Catarina, proporcionando assim, emprego e renda à população. Esta pesquisa também propõe ações futuras que poderão colaborar na realização de estudos de viabilidade técnica utilizando agregados de RCD na produção de agregados para pavimentação, confecção de blocos sem função estrutural, peças para o meio fio, entre outros, beneficiando a população e o Município de Petrolina
Besides the fact that it is the cause of some environmental impact due to the great consumption of raw material and generation of residues, construction engineering is recognized as one amongst the most important activities that contributes to the economic and social development of our country. Within underdevelopment countries the generation of CDW (Construction and Demolition waste) in demolition works between the years 94-99 varied from 32 to 99 tons/year. CDW in Brazil is not different. In 2005, a research carried in 11 municipalities showed that the medium CDW was 59% as well. The municipality of Petrolina is located in the arid backlands of the state Pernambuco, the current population is 268,339 and still doesnt own a system for management of the CDW as required in the resolution 307 of CONAMA(2002) (National Council for Environmental Issues). Willing to contribute to the solving of this problem, the present dissertation brings a survey of variability of CDW in the municipality of Petrolina and verifies its recycling potential. The research is based on exploratory and descriptive field work and aims to identify the varied waste material discarded through the work of ten civil engineering companies and also to identify 11(eleven) points of irregular discard and the possible re-use of the discarded material. Results show that 91, 2% of residues are class A, waste with recycling potential. 45, 5% of the waste is ceramic, 23, 6% is mortar, 14, 1% is concrete and 8% is sand. The other 8, 8% are discard of wood, plastic and plaster. Despite the lack of place for disposal, private and governmental companies try to adjust themselves to what is required in resolution 307, specially regarding to recycling of CDW.There have been implemented a recycling industry in a disposal area called Raso da Catarina therefore providing jobs for the population. The present work of study also suggests some future action that may collaborate in studies for the use of CDW aggregates for paving, blocks with non-structural function and pieces for sidewalk, benefitting population and municipality as a whole

Abstract:
With the outlook of improving seismic vulnerability assessment for the city of Bishkek (Kyrgyzstan), the global dynamic behaviour of four nine-storey r.c. large-panel buildings in elastic regime is studied. The four buildings were built during the Soviet era within a serial production system. Since they all belong to the same series, they have very similar geometries both in plan and in height. Firstly, ambient vibration measurements are performed in the four buildings. The data analysis composed of discrete Fourier transform, modal analysis (frequency domain decomposition) and deconvolution interferometry, yields the modal characteristics and an estimate of the linear impulse response function for the structures of the four buildings. Then, finite element models are set up for all four buildings and the results of the numerical modal analysis are compared with the experimental ones. The numerical models are finally calibrated considering the first three global modes and their results match the experimental ones with an error of less then 20%.

Abstract:
Questa tesi si propone di indagare sulla modellazione degli elementi non strutturali relativi alle pareti di tamponamento interne ed esterne, cercando di quantificare la differenza indotta dalle diverse strategie di modellazione sul valore dell'indice di vulnerabilità sismica con riferimento a edifici strategici. A tale scopo vengono analizzati due casi studio: il liceo Benedetto Croce di Avezzano e il liceo Varano di Camerino, entrambi edifici a telaio in c.a. oggetto di adeguamento sismico tramite torri dissipative esterne dotate di dissipatori viscosi alla base. Per entrambi i casi di studio, sono stati implementati tre modelli sia prima che dopo l'adeguamento, caratterizzati da un livello crescente di dettaglio: modello A con solo le componenti strutturali, modello B con tamponature esterne modellate come puntoni equivalenti secondo letteratura e modello C con pareti di tamponamento esterne ed interne calibrate attraverso i risultati dei test dinamici in situ. Per quanto riguarda la fase di pre-retrofitting, il calcolo dell'indice di vulnerabilità sismica è stato effettuato mediante analisi statica non lineare (pushover). Per quanto riguarda la fase post-retrofitting, il calcolo dell'indice di vulnerabilità sismica è stato effettuato mediante analisi dinamica non lineare (I.D.A). I risultati sono mostrati in termini di confronto tra le curve di capacità ottenute con analisi push over (pre-retrofitting) e con analisi dinamiche incrementali, per i diversi modelli implementati. Inoltre, i risultati sono mostrati anche in termini di livello di intensità dell'azione sismica necessaria per raggiungere uno stato limite predeterminato per il modello A, il modello B e il modello C.
This thesis aims to investigate on the modelling of the non-structural elements related to internal and external infill walls, trying to quantify the difference induced by different modelling strategies on the value of the seismic vulnerability index with reference to strategic buildings. On this purpose, two case studies are analysed: the Benedetto Croce high school in Avezzano and the Varano high school in Camerino, r.c. frame buildings retrofitted with external steel towers equipped with viscous dampers at the basis. For both case studies, three models are implemented, before and after the retrofitting, which are characterized by an increasing level of detail: model A with only structural components, model B with external infill panels modelled as equivalent connecting struts according to literature, and model C with external and internal infill walls calibrated through the results of in-situ dynamic tests. As regards the pre-retrofitting phase, the calculation of the seismic vulnerability index was carried out by means of nonlinear static analysis (pushover). As for the post-retrofitting phase, the calculation of the seismic vulnerability index was carried out by means of non-linear dynamic analysis (I.D.A). The results are shown in terms of comparison between the capacity curves obtained with push over analyses (pre-retrofitting) and with incremental dynamic analyses for the different model. In addition, the outcomes are shown also in terms of intensity level of the seismic action necessary to reach a predetermined limit state for model A, model B and model C.

A significativa quantidade de resíduos gerada pelo setor da construção civil é hoje um grande problema a ser enfrentado pelas empresas construtoras e pelo Poder Público, exigindo a adoção de políticas setoriais por parte dos municípios. O que se constata, porém, é que a exigência e fiscalização do cumprimento e adequação a estas normas até hoje não são efetivas. Neste contexto, esta dissertação de mestrado apresenta diretrizes para o desenvolvimento de um sistema de gerenciamento de resíduos de construção e demolição para o Município de Gramado-RS adequado à Resolução 307/2002 do CONAMA, sob o ponto de vista do poder público. Como estratégia de pesquisa foi realizado um estudo de caso junto à Prefeitura do município. Dentre as etapas do estudo, foi estimada a quantidade de resíduos de construção e demolição gerada no município, diagnosticado o sistema de gestão empregado pela prefeitura e identificados os pontos falhos e oportunidades de melhorias. Como principais resultados o trabalho apresenta diferentes ações que devem ser realizadas por parte do poder público, que envolvem a estrutura da própria Prefeitura Municipal, empresas construtoras, empresas envolvidas com a coleta de resíduos e a sociedade em geral. Questões como a disponibilização de áreas para deposição de pequenos volumes de resíduos, o trâmite de aprovação mais unificado nos setores da Prefeitura Municipal e a exigência da licença ambiental da empresa de recolhimento de entulho para atendimento aos requisitos técnicos e ambientais, são consideradas fundamentais para o início do processo. Por outro lado, as empresas construtoras também precisam desempenhar o seu papel, adquirindo conhecimento, disponibilizando-os aos seus funcionários e desenvolvendo seus projetos de gerenciamento de resíduos.
The significant amount of waste generated by the construction industry is now a major problem being faced by construction companies and the government, demanding the adoption of sectoral policies by the municipalities. What is evident, however, is that the requirements and monitoring process of compliance and adequacy of these standards are still not effective. In this context, this master degree dissertation presents guidelines for developing a construction and demolition waste management system for the city of Gramado-RS suitable for the CONAMA Resolution 307/2002 from the point of view of county public power. As a research strategy was a case study conducted at the City Hall of the county. Among the stages of the study we estimated the amount of construction and demolition waste generated in the county, diagnosed the management system employed by the city and identified the defective points and improvement opportunities. As main results the paper presents various actions to be undertaken by the government, involving the structure of their own City Hall, construction companies, companies involved in waste collection and society in general. Issues such as the provision of areas for disposal of small volumes of waste, the procedure adopted more unified in the sectors of the City and the requirement for the environmental permit from the collector of debris to meet the technical requirements and environmental impacts, are considered fundamental to the top process. Furthermore, construction companies must also play its role, acquiring knowledge, making them available to their employees and developing their projects for waste management.

Abstract:
När byggnader projekteras används klimatfiler från 1981-2010 för att dimensionera konstruktionen och energisystemet. Detta leder till att byggnader dimensioneras för ett klimat som varit och inte ett framtida klimat. SMHI har tagit fram olika klimatscenarier för framtiden som beskriver möjliga utvecklingar klimatet kan ta beroende på fortsatt utsläpp av växthusgaser. Dessa scenarier kallas för RCP (Representative Concentration Pathways). I denna studie används två olika klimatscenarier, RCP4,5 och RCP8,5. Siffran i namnet står för den strålningsdriving som förväntas uppnås år 2100. I RCP4,5 kommer medelårstemperaturen öka med 3 °C fram till år 2100 jämfört med referensperioden 1961-1990.  För samma tidsperiod sker en ökning på 5 °C enligt RCP8,5.  Ett flerbostadshus certifierad enligt Miljöbyggnad 2.2 nivå silver placerat i Vallentuna i Stockholms län används i denna studie som referensbyggnad. Byggnaden simuleras i programmet IDA ICE där den utsätts för RCP4,5 och RCP8,5. Resultatet visar att byggnaden inte skulle klara av kraven för Miljöbyggnad 2.2 gällande termiskt klimat sommar i något av de två klimatscenarierna. De operativa temperaturerna blir för höga i byggnaden utan att tillsätta komfortkyla.  Byggnaden ändras för att se vilka faktorer som kan förbättra resultatet gällande det termiska klimatet. Resultatet visar att värmelagringsförmåga hos byggmaterial och solavskärmning har störst påverkan på det termiska klimatet.  I studien gjordes flertal olika kombinationer av byggnadsutformningar. Enbart kombinationen av en tung stomme av betong tillsammans med fönster med lägre g-värde klarar kraven för Miljöbyggnad 2.2 i RCP4,5 och RCP8,5 utan komfortkyla. Kombinationen får lägst energianvändning i RCP8,5 av de olika kombinationerna som testats i studien.  En kombination av tung stomme av KL-trä med lågt U-värde, fönster med lägre g-värde och komfortkyla får lägst energianvändning i grundklimatet och RCP4,5 av de olika kombinationerna som testats i studien trots användningen av komfortkyla.  Frågan om vilket alternativ som är bäst ur ett hållbarhetsperspektiv är svårt att svara på. Det finns många aspekter som behöver tas i hänsyn till som byggnadens totala klimatavtryck både i tillverkning och användning. Oavsett val av konstruktion är det viktigt att projektera för att komfortkyla och solavskärmning skall kunna appliceras när ett varmare klimat råder.
When buildings are designed climate files from 1981 to 2010 are used to construct the building and its energy system. This leads to building being designed to a climate that has been and not to a future warmer climate that will come. SMHI has developed different climate scenarios for the future that describe different paths the climate can take depending on continued emissions of greenhouse gas. This climate scenarios are called RCP (Representative Concentration Pathways) In this study two of the climate scenarios, RCP4,5 and RCP8,5 are used. The number in the name stands for the radiation forcing that is expected in the year 2100.  In RCP4,5 the mean average air temperature will increase with 3 °C until year 2100 compared to the reference period 1961-1990. In the same time period RCP8,5 will increase with 5 °C.  An apartment building certified according to Miljöbyggnad 2.2 level silver placed in Vallentuna, Stockholms län is used as a reference building. The building is simulated through the simulation software program IDA ICE where it´s exposed to RCP4,5 and RCP8,5. The results demonstrate that the reference building would not meet Miljöbyggnad 2.2 requirement in the indicator about thermal comfort during summer. The operative temperature in the building is too high unless comfort cooling is used.  The design of the building changes to see what factors can improve the results regarding the thermal comfort. The results demonstrate that thermal conductivity and solar shading has the greatest impact on thermal comfort.  In this study several combinations of different building designs were made. Only the combination of a concrete frame with windows with low g-value met the requirement of Miljöbyggnad 2.2 regarding the thermal comfort during summer without using comfort cooling in RCP4,5 and RCP8,5. The combination had the lowest energy demand in RCP8,5 of all the combinations tested in the study.  A combination of cross laminated wood frame with low U-value, windows with low g-value and comfort cooling had the lowest energy demand in the original climate file and RCP4,5 despite the use of comfort cooling.  The questing about which building construction is the best from a sustainable perspective is difficult to answer. To answer that question the building´s total climate footprint in both production and use must be calculated. Regardless of the choice of building construction it is important to have in mind when designing a building that comfort cooling and solar shading should be easily applied when a warmer climate will prevail.

Abstract:
Hemp (Cannabis sativa) is an agricultural crop that can be used as a building material in combination with lime and cement. A composite building material that combines a cementitious binder (building limes and cement) with hemp shives, the woody core of the hemp stalk is generally referred to as hemp concrete (HC). However, industrial facilities to separate hemp shives and fibres are currently not available in India. HC has many advantages as a building material but it is not load-bearing and must be used in combination with a load-bearing RCC frame. The aim of this research was to evaluate the feasibility of using both hemp shives and fibres in a HC to determine an optimal mix of the different binding agents and to investigate if adding cement binder would improve the mechanical strength of the material. The effects on compressive strength of pre-mixing the binder or creating perforations in the test specimens were also investigated.

Abstract:
Sikawrap becomes preferable for strengthening and retrofitting of RC structural elements due to its high strength-to-weight and high stiffness to weight ratios. This study examines the structural performance and strengthening of RCC interior joint with variable beam depth using Sika wrap. In the first model, conventional connection is compared with beam, column and joint failure connection. In the second model, strengthening of beam connection is done by Lstrip method, embedment method and web-bounded method. In the third model, strengthening of column connection is done by L-shaped plate method and near surface mounted and wrap method. In the fourth model, strengthening of joint connection is done by X, U and T-shape method. In the fifth model, strengthening of beam column connection is done by L-shaped plate and wrap method and full wrap method. The structure will be analyzed using seismic analysis. This can be done by varying the depth of beam and finding which one possess more strength. Non-linear lateral loading test is carried out for beam-column connection with varying depth of beam on studying joint strength, target displacement and ductility for above all methods. This joint is the most critical portion of a building under earthquake due to diagonal crack failure, which leads to the collapse. Therefore, such joints need special attention to increase the capacity of existing damaged joints through retrofitting. In this paper the idea of using Sikawrap are studied. Sikawrap becomes preferable for strengthening and retrofitting of RC structural elements due to its high strength-to-weight and high-stiffness-to- weight ratios. Sika wrap comprises of unidirectional, carbon or glass fibre fabrics and structural epoxy resin based, impregnating resins. These unique combinations provide a wide range of strengthening and upgrading solutions to meet the many varied demands of different product and application. Strengthening methods are provided for defected beam, column and joints. The structure will be analysed using seismic analysis. It can be analysed by first finding the best model. This can be done by varying the depth of beam and finding which one possess more strength. Non-linear lateral loading testing is carried out for a beam-column connection with varying the depth of beam on studying the joint strength, target displacement and ductility for above all methods. The effective specimens are then studied under cyclic test.

Abstract:
This paper briefly introduces the weld cladding structure, its common defects during the manufacture and operation stage and its application in pressurized water reactor nuclear power plants. Some ultrasonic testing codes or standards for nuclear power plant pressure vessel or piping, such as ASME BPVC volume V & III & XI, Germany KTA 3201.3 and 3201.4 code, France RCC-M and RSE-M code, and Russia code of light water nuclear power plants were discussed. The difference of those codes and some feed backs have been analyzed and discussed. Furthermore, these works really benefit the compiling of NB/T 20003.2-2010, Non-destructive Testing for Mechanical Components in Nuclear Island of Nuclear Power Plants-Part 2: Ultrasonic Testing, as China building more and more nuclear power plants. It was concluded that we shall pay more attention to the inspection of cladding, not only at manufacture stage but in operation outage stage. One of important work is periodically updating the inspection standard revision. It was believed that improving the cladding defects inspection reliability and effectiveness is very important to the safety of nuclear power plants operation in China and in the world.

Abstract:
Seismic isolation (SI) advantages for new buildings are well known: not only it allows to avoid damage of both structural and non structural elements under strong earthquake, but it mantains building functionality as well. This is possible thanks to strong reduction of accelerations and interstorey drift in the superstructure, i.e. the part of structure above the isolation layer. SI offers additional advantages for seismic retrofit of existing buildings. The main advantage is that the works can be limited at one floor (usually the basement, plus the foundation), without any strenghtening on the superstructure. Consequently, the building can be used during the retrofit works. The safety of the retrofitted building increases significantly. Reaching exactly the same safety level of a new building in the same site would be possible, but it would need some strenghtening in the superstructure, and thus is usually avoided in order to keep the building in function during the works. It is worth noting that for the seismic isolation system, the safety is the same than for a new building. The paper presents in detail three case studies of framed r.c. buildings built in the 1980s and now under retrofit with seismic isolation, that could be representative of many other buildings. During 2009 L'Aquila earthquake, those residential buildings were only slightly damaged, and immediately repaired but without any improvement of their seismic performance. Now the retrofit design is carried out for an earthquake stronger than the 2009 earthquake. Despite the buildings are in the same area (ag=0.261g for the Life Safety Limit State earthquake; ag=0.334g for the Collapse Limit State earthquake, used to design the seismic isolation system), the design spectrum is different because of different type of soil. The isolators are inserted in the basement or in the ground floor that host the garages, thus without affecting the apartments. The safety level reached in the three buildings was higher than 70% of that of new buildings in the same site, while before retrofit it was lower than 16%

Abstract:
Abstract During the recent decades, the use of non-destructive tests has reached greater attention due to its high versatility and the possibility of extending the investigations on a great number of points. On the other side, the existence of a wide building stock realized in reinforced concrete, which is reaching the end of its service life, has increased the research on the assessment of their safety level. In this field, one of the most important parameters for r.c. structure is the concrete compressive strength, which “classically” is evaluated by means of compression tests on drilled cores. However, usually the extension of such procedure to a high number of points is quite difficult due to logistic and economic reasons. The use of non-destructive tests may overcome these limits, but still needs further investigations to improve the calibration process of the relationship between the acquired data and the compressive strength. The present paper deals with this issue and discusses the results of the investigations on r.c. buildings in Bari (Italy) which make use of both destructive and non-destructive tests. The data are analyzed by considering several test scenarios and by evaluating the variability of parameters related to the calibration process.

Building capacity for Quality Teaching Rounds – Victoria. Final report. Australian Council for Educational Research, June 2023. http://dx.doi.org/10.37517/978-1-74286-713-7.

Full text
Abstract:
The Australian Council for Educational Research (ACER) was commissioned by the Teachers and Teaching Research Centre (TTRC) at the University of Newcastle to conduct an independent randomised controlled trial (RCT), with the goal of examining effects of Quality Teaching Rounds (QTR) on student outcomes and teachers’ practice in Victorian high schools. A total of 19 schools participated in Quality Teaching Rounds in 2022, with 20 schools in the wait list control. Data were gathered in an ongoing manner during the evaluation with: Progressive Assessment Tests in Mathematics (PAT-M) and reading (PAT-R) – baseline and follow up; student self-efficacy and aspiration surveys – baseline and follow up; teacher surveys – one questionnaire administered every term; implementation fidelity check surveys for teachers to complete for each QT Round; and implementation fidelity checks with onsite visits from ACER staff for 33% of the treatment schools. Key findings include: The mixed model analysis showed that treatment was not a significant predictor of PAT-R and PAT-M outcomes. Differences in student responses to the self-efficacy and aspiration surveys were identified. The control group showed a significant increase in the level of education that they aspired to complete (p = 0.037). Teachers in the control group had statistically significant growth in teacher efficacy, while those in the treatment group showed statistically significant lower teacher student support. Within the QTR process, the longest time was spent on discussing the coding and the individual coding process. Key observations identified from analysis of the fidelity check data are: teacher stress due to high rates of absenteeism, varied use of the Classroom Practice Guide, and analytical conversations about some elements and terms.

Abstract:
This paper draws overarching conclusions based on a synthesis of previously published case studies that examined the impact of EU military training missions (EUTMs) in Somalia (EUTM Somalia, 2010–), Mali (EUTM Mali, 2013–), the Central African Republic (CAR) (EUTM RCA, 2016–). It concludes that EUTMs are relevant niche operations. Despite difficult circumstances beyond the control of the missions, EUTM training and advisory efforts have increased the effectiveness of partner armed forces. While these gains have been marginal in CAR and Somalia, they have been a bit more pronounced in Mali. Yet, broader security sector reform and defence sector reform efforts to improve the accountability and governance of defence and security sectors have become bogged down. The main challenge is that EUTMs are generally mandated to implement largely technical and tactical agendas in contexts where the ongoing armed conflict and the politics of the security sector are not conducive to building professional national security forces. As a consequence EUTMs find themselves caught up in interlinked and partially overlapping dilemmas. This study concludes with seven partly overlapping recommendations to EU member states and to EUTMs to address the main limitations that are restricting the impact of the missions.
