The construction of small houses was started many years before Christ, and the development of this field has led many architects and engineers to a higher level of buildings. Mainly the buildings in terms of height are classified into three types: low-, medium- and high-rise buildings. In this particular study, medium or med-rise buildings are investigated. Reaching the fully finished building stage is not easy, and it requires many steps. Taking into account the step-by-step tasks for proper performance completion, economical point of view, performance period estimation and other considerations, it is essential to organise (plan) the work before it starts accurately; that is why a work breakdown structure (WBS) template is vital in the planning, design and construction of buildings. In this paper, an overview and a WBS template for construction planning of the med-rise buildings are submitted. It was seen that for the successful construction of a mid-rise building, 14 steps are required prior completion, and among all steps, construction step takes more time for completion.

As in many other building types, space efficiency in mid-rise timber apartment buildings is one of the critical design parameters to make a project feasible. Space efficiency depends on varying selection criteria related to construction materials, construction methods, and proper planning. To date, no study provides a comprehensive understanding of space efficiency in mid-rise timber apartment buildings. This paper examined data from 55 Finnish mid-rise timber apartment buildings built between 2018 and 2022 under the Finnish Land Use and Building Act to increase the understanding of which factors and design parameters influence the space efficiency of mid-rise timber apartment buildings. The main findings of this study indicated that: (1) among the case studies, the space efficiency ranged from 77.8% to 87.9%, and the average was 83%; (2) the mean values of the ratios of structural wall area to gross floor area, vertical circulation area to gross floor area, and technical spaces (including shafts) to gross floor area were found to be 12.9%, 2.6%, and 1.5%, respectively; (3) construction methods or shear wall materials make no significant difference in terms of space efficiency, and there is no scientific correlation between the number of stories and space efficiency; (4) the best average space efficiency was achieved with central core type, followed by peripheral core arrangement. This research will contribute to design guidelines for clients, developers, architects, and other construction professionals of mid-rise timber apartment building projects.

This paper gives a brief presentation about different types of analysis, plastic hinge, moment-resisting frames (MRFs) and shear walls (SWs) in reinforced concrete (RC) Structures. ETABS computer software is employed to model and analyse the structures applying the pushover. The performances of the modelled structures are also evaluated considering different parameters such as the number of stories, spans length, shear walls, reinforcement yield strength and characteristic strength of concrete. The study includes two cases, which are moment-resisting frames with and without shear walls (i.e. MRFs and MRF-SWs, respectively). Each case covers low-, mid- and high-rise buildings. In this regard, a comparative study has been performed for the results obtained from all models. It was observed that the stiffness of MRFs compared to MRF-SWs was less and also the stiffness of low-rise frames was higher than that of mid-rise and high-rise frames. Technically this means that a low-rise building is stiffer than a mid-rise building and a mid-rise building is stiffer than a high-rise building. Additionally, when the span length increases, the stiffness of the building decreases. Therefore, it can be concluded that the span length is inversely proportional to the stiffness. Finally, all stiffness values were calculated taking into consideration the displacement and base shear at the first hinge formation on the pushover curve of each model.

The constructed building in the urban area is subject to wind characteristics due to the influence of surrounding buildings. The residential complexes currently being built in Iraq represent a case study for the subject of this research. Therefore, the objective of this study is to identify the interference effect because of adjacent buildings effects on the mid-rise building. The speed and pressure of the wind have been numerically simulated as well as wind load has been simulated by using a virtual wind tunnel which is available in Autodesk Robot Structural Analysis, RSA, software. Two identical adjacent buildings have been simulated and many coefficients were included in this study such as the spacing, directionality, and elevation of adjacent building coefficients. The results of the study showed that the neighboring building could increase or decrease the wind pressure significantly so that it cannot be neglected.

During the recent earthquakes, it has been observed that structural irregularities are one of the main reasons of the building damage. Irregularities are weak points in a building which may cause failure of one element or total collapse of the building during an earthquake. Since Albania is a country with moderate seismicity which has been hit by earthquakes of different magnitudes many times establishes the need to study the effect of irregularities is well-founded. The main structural irregularities encountered in Albanian construction practice consist of short column, large and heavy overhangs and soft story. In this study, these types of irregularities are considered in two different types of buildings, low and mid-rise reinforced concrete frame buildings represented by 3- and 6- story respectively. Pushover analyses are deployed to get the effect of structural irregularities on RC building response. A building set is chosen to represent the existing construction practice in the region; regular framed building and buildings with irregularities such as soft stories, short columns, heavy overhangs and the presence of soft story with heavy overhangs. The analyses have been conducted by using ETABS and Seismosoft software. Pushover curves of building set are determined by nonlinear static analysis in two orthogonal directions. Comparative performance evaluations are done by considering EC8 and Albanian Seismic codes (KTP-N2-89). From the obtained results, it is observed that low and mid-rise structures with soft story- two sided overhangs and short column are more vulnerable during earthquakes.

Cross-laminated timber (CLT) is made up of multilayered timber stacked perpendicularly, which improved the dimensional stability and allowing CLT to has high bearing capacity in its two direction. Despite all the advantages, CLT has not yet gain much attention in Indonesian, especially the utilization in mid-rise building construction. In order to have a better understanding about CLT as main structural element, the behaviour of mid-rise building made of CLT was assessed by running a 3D model of 5-story building by combining building code in Indonesia with CLT parameter from previous researcher as well as recommended adjustment from previous researchers. The research shows that CLT building statisy the allowable parameter for mid-rise building in Indonesia.

Frequent and extreme heat waves have strongly influenced the sustainable development of cities and resulted in a higher level of mortality in residents. Using the Local Climate Zone (LCZ) classification scheme, combined with the factors of land surface temperature (LST), building age (BA), and housing price (HP), and the normalized values of which represent heat exposure, sensitivity, and adaptability, respectively, this paper investigates a practical method for assessing the heat vulnerability of different LCZ classes in the old areas of a Chinese megacity, taking the Yuzhong district of Chongqing city as a case study. The results reveal that the distribution of LCZ classes in this study area exhibits a typical circle-layer distribution pattern from the city center to the suburbs. Heavy industry areas are the most vulnerable, with the highest exposure to heat waves, the oldest building age and the lowest housing price. Compact class areas (compact high-rise, compact mid-rise and compact low-rise) are usually more vulnerable than open class areas (open high-rise, open mid-rise, and open low-rise) and low-rise buildings are always more susceptible to heat waves than mid-rise and high-rise buildings. The methods and findings can help us to better understand the comprehensive and space–time action rules of heat vulnerability, thereby inspiring scientific and rational urban planning strategies to mitigate or adapt to urban heat weaves towards the sustainable development of cities and society.

This paper investigates the correlation between ground motion parameters and displacement demands of mid-rise RC frame buildings on soft soils considering the soil-structure interaction. The mid-rise RC buildings are represented by using 5, 8, 10, 13, and 15-storey frame building models with no structural irregularity. A total of 105 3D nonlinear time history analyses were carried out for 21 acceleration records and 5 different building models. The roof drift ratio (RDR) obtained as inelastic displacement demands at roof level normalized by the building height is used for demand measure, while 20 ground motion parameters were used as intensity measure. The outcomes show velocity related parameters such as Housner Intensity (HI), Root Mean Square of Velocity (Vrms), Velocity Spectrum Intensity (VSI) and Peak Ground Velocity (PGV), which reflect inelastic displacement demands of mid-rise buildings as a damage indicator on soft soil deposit reasonably well. HI is the leading parameter with the strongest correlation. However, acceleration and displacement related parameters exhibit poor correlation. This study proposed new combined multiple ground motion parameter equations to reflect the damage potential better than a single ground motion parameter. The use of combined multiple parameters can be effective in determining seismic damages by improving the scatter by at least 24% compared to the use of a single parameter.

The objective of this paper is to report and analyse strategies for cost reduction, design processes, and procurement models of one wooden nearly Zero Energy Building (nZEB) in Norway. The building investigated in this paper is the Moholt Allmenning, a newly-built student accommodation located in Moholt, Trondheim. Interviews with the building's owner and the contractor were carried out to obtain information on the decision-making process during the procurement phase, the planning phase, and the execution phase. The results show that the environmental goal and the criteria set for the use of wood in the tender announcement were a critical driving force for choosing cross laminated timber (CLT) in the final design. The results also show that the cost of using CLT in student residences is competitive against using concrete and steel. Given the requirement of little greenhouse gas (GHG) emissions from materials production in nZEBs, the use of CLT is however a better choice.

Especially, the large-scale loss of life and property caused by the significant earthquakes in recent years has brought the importance of research and measures to be taken on this issue. Determining and analysing the ever-increasing building stock of the cities and detecting and managing all information related to buildings are important in terms of spatial planning and urban transformation. This study aims to determine tectonic characteristics calculating a and b values of Gutenberg- Richter magnitude-frequency relation which forms the basis of earthquake statistics for all cities in Turkey and the reinforced-concrete buildings which are primarily risky in terms of urban transformation. For this purpose, a total of 1620, 5-storey buildings from all provinces of Turkey were assessed. Twenty reinforced concrete buildings from each province were taken into consideration which has 5-stories. The first stage evaluation method specified in the principles regarding the identification of risky buildings issued in 2013 by the Republic of Turkey, Ministry of Environment and Urbanization was used in this study. The performance scores for 1620 buildings were calculated by using this method. A risk priority map was created for the provinces, taking into account for these buildings. The study aims to determine risk priorities of site and mid-rise reinforced-concrete buildings among the cities. The results obtained were interpreted and recommendations were made.

The objective of this project aimed to quantify and compare the environmental impacts associated with the construction of a mid-rise office building. Two alternative scenarios were considered; a traditional cast-in-place, reinforced concrete frame and a laminated timber hybrid design, which utilized engineered wood products including glulam and cross-laminated timber (CLT). The study boundary was cradle-to-gate and encompassed the structural support system and the building enclosure.
A case study building; Discovery Place – Building 12, was selected to represent a typical five-storey office building constructed in North America. Floor plans, elevations, material quantities and design loads associated with the concrete-framed building design were obtained from issued-for-construction engineering drawings. A functionally equivalent, laminated timber design was then conceived, based on the requirements outlined in CAN/CSA-O86-01. Design values for locally produced CLT panels were established from in-house material testing results. A life cycle assessment of CLT, manufactured in British Columbia with mountain pine beetle killed wood, was developed based on primary inventory data collected from a pilot-scale manufacturing facility. Life cycle inventory and impact assessment data for building materials was obtained from secondary sources including BEES® 4.0, ATHENA® EcoCalculator, CORRIM, and the US LCI. TRACI, an impact assessment characterization methodology, was employed to translate inventory flows into environmental impact indicators.
The environmental comparison of building design alternatives was based on 11 impact categories. The results concluded that the laminated timber building design was associated with a lower environmental footprint in 10 of 11 categories. At a minimum, the heavy timber design demonstrated a 14% improvement, when considering acidification potential. At a maximum, the timber design exhibited a global warming potential that was 71% less than the concrete design. Fossil fuel depletion was the only category where the concrete design was superior, displaying a 6% advantage over the timber scenario. The cumulative embodied energy of construction materials was also calculated; with results estimating energy contents of 116 and 66 terajoules for the timber and concrete designs, respectively. The concrete building acquired 20% of its energy from renewable sources, whereas in the timber-framed case, renewables accounted for over 60% of the combined feedstock and process energy.

zcebe Co-Supervisor: Assoc. Prof. Dr. BariS Binici May 2009, 162 pages FRP retrofitting allows the utilization of brick infill walls as lateral load resisting elements. This practical retrofit scheme is a strong alternative to strengthen low to mid-rise deficient reinforced concrete (RC) structures in Turkey. The advantages of the FRP applications, to name a few, are the speed of construction and elimination of the need for building evacuation during construction. In this retrofit scheme, infill walls are adopted to the existing frame system by using FRP tension ties anchored the boundary frame using FRP dowels. Results of experiments have previously shown that FRP strengthened infill walls can enhance lateral load carrying capacity and reduce damage by limiting interstory drift deformations. In previous, analytical studies, a detailed mathematical model and a simplified version of the model for compression struts and tension ties was proposed and verified by comparing model estimations with test results. In this study, an existing 9-storey deficient RC building located in Antakya was chosen to design and apply a hybrid strengthening scheme with FRPs and reduced number of shear walls. Linear elastic analysis procedure was utilized (force based assessment technique) along with the rules of Mode Superposition Method for the reftrofit design. FRP retrofit scheme was employed using the simplified model and design was conducted such that life safety performance criterion is satisfied employing elastic spectrum with 10% probability of exceedance in 50 years according to the Turkish Earthquake Code 2007. Further analytical studies are performed by using Modal Pushover and Nonlinear Time-History Analyses. At the end of these nonlinear analyses, performance check is performed according to Turkish Earthquake Code 2007, using the strains resulting from the sum of yield and plastic rotations at demand in the critical sections. CFRP retrofitting works started at October 2008 and finished at December 2008 for the building mentioned in this study. Eccentric reinforced concrete shearwall installation is still being undertaken. All construction business is carried out without evacuation of the building occupants. This project is one of the first examples of its kind in Turkey.

The objective of this investigation is to evaluate the geo-climatic potential for comfort cooling energy savings in mid-rise office buildings applying advanced natural ventilation (ANV) approach based on the stack-effect. The region of interest is the Mediterranean coastline of Catalonia with selected reference geographical locations—the cities of Barcelona, Terrassa and Tarragona. In the first part of this research is evaluated the climatic potential for natural ventilation (CPNV) for each location, as a theoretical level of availability of natural ventilation (NV) based on the model of adaptive thermal comfort. For a comparison of geo-climatic potentials in a wider regional context, additional reference locations are chosen along the Northern Mediterranean: Valencia, Marseille, Rome, Koper, Split, Athens and Nicosia. Generated results confirm that NV is feasible mainly from April to October while in July and August is considerably limited due to unfavourable climate conditions. The second part of the work examines cooling energy savings of the hypothetical mid-rise office-type building model “A”. Applied building performance simulations (BPS) demonstrates achieved total yearly cooling energy savings in the region of Catalonia between 22% and 51%. The same model positioned along the Northern Mediterranean displays cutting in yearly cooling energy loads in a wider range—from 6% to 51%.The following section evaluates levels of climate change vulnerability applying climate scenarios for the selected time-slices—the years 2050 and 2080. It is indicated that the potential of ANV will be reduced close to zero in July and August in 2080. However, the introduction of selected assisted cooling techniques demonstrates that this impact can be absorbed approximately back to the previously evaluated scale in the horizon of 2050. In the last part of the investigation, the new defined building model “B” displays an improvement of comfort cooling energy efficiency: selected NV techniques are merged in order to take advantage of lower nocturnal outdoor temperatures by passive means, whose potential is reflected on the decrease of active day-time cooling loads. For this purpose, the positioned model in Barcelona achieves the yearly reduction of cooling energy loads by 65% in present-time weather conditions. At the conclusion, under projected climate configurations for 2050 and 2080, in Barcelona Terrassa and Tarragona, the series of BPS displays a higher level of climate resilience and the overall reduction of cooling energy loads within 53% and 59%.
The key-contribution and the novelty of this research is in the performed series of experimental BPS of the building model “A” where are detected ANV system’s weaknesses as a result of estimated unfavourable climate effects. Relative to observed limited cooling performances, ANV is shifted from an autonomous comfort cooling concept to being a part of a complex ventilative system with specific day- and night-time cycles. Such a new established design approach based on dynamic heat storage is associated with an introduction of lower nocturnal and early morning outdoor air temperatures, as being less affected with future regional climate change. An achieved advantageous momentum in energy performances is categorized through strengths and opportunities. Thereby, the building model “B”, the outcome of this investigation, represents the climate responsive building form with an integrated climate sensitive comfort cooling system, which delivers a higher level of energy efficiency—seen as an acquired factor of resilience towards estimated climate change threats. Such a conceptualised hypothetical building prototype may prove to be a beneficial contributor in the current process of rapid deployment of renewable energy sources in the regional building sector, observed as well from the perspective of the ongoing European Union’s energy transition.El objetivo de esta investigación es evaluar el potencial geo-climático para el ahorro de energía de enfriamiento de confort en los edificios de oficinas de mediana altura aplicando el concepto de ventilación natural avanzada (ANV). El enfoque es en la costa Mediterránea de Cataluña y las ubicaciones geográficas seleccionadas: Barcelona, Terrassa y Tarragona. La primera parte de investigación evalúa el potencial climático de ventilación natural (CPNV), un nivel teórico de disponibilidad de ventilación natural (NV) aplicando el modelo de confort térmico adaptativo. Para una comparación de los potenciales geo-climáticos en un contexto regional más amplio, están elegidas las ubicaciones a lo largo del Mediterráneo Norte: Valencia, Marsella, Roma, Koper, Split, Atenas y Nicosia. Los resultados confirman que NV es factible principalmente desde abril hasta octubre, mientras que en julio y agosto es considerablemente limitada. La segunda parte del trabajo examina los ahorros de energía de enfriamiento de un hipotético modelo “A” del edificio de oficinas de media altura. Las simulaciones de rendimiento de edificios (BPS) en la región de Cataluña demuestran una reducción anual de cargas de enfriamiento entre 22% y 51%. El mismo modelo posicionado a lo largo del Mediterráneo Norte muestra la reducción de las cargas anuales en un rango más amplio, entre 6% y 51%. La siguiente sección evalúa los niveles de vulnerabilidad al cambio climático aplicando escenarios climáticos para los años 2050 y 2080. Se indica que el potencial de ANV se reducirá cerca de cero en julio y agosto de 2080. Sin embargo, la introducción de unas técnicas de enfriamiento asistidas demuestra que ese impacto puede ser absorbido aproximadamente a la escala previamente evaluada en el horizonte de 2050. La última parte de investigación exhibe que el modelo “B” tiene un mejor nivel de la eficiencia energética del enfriamiento de confort: se fusionan técnicas de NV seleccionadas para aprovechar las temperaturas exteriores nocturnas más bajas por medios pasivos, cuyo potencial se refleja sobre la disminución de las cargas de enfriamiento activo diurno. Para este propósito, el modelo posicionado en Barcelona consigue la reducción anual de las cargas de enfriamiento en un 65% en las condiciones meteorológicas actuales. En conclusión, bajo las configuraciones climáticas proyectadas para 2050 y 2080, en Barcelona, Terrassa y Tarragona, la serie de BPS muestra un mayor nivel de resiliencia climática con la reducción de las cargas de enfriamiento entre 53% y 59%. El aporte clave de la investigación se encuentra en BPS experimentales del modelo “A” donde se detectan las debilidades del sistema ANV como consecuencia del cambio climático estimado. En relación con los rendimientos de enfriamiento limitados, ANV se cambia de un concepto autónomo a ser parte de un sistema de ventilación más complejo con los ciclos específicos diurnos y nocturnos. Este nuevo enfoque de diseño establecido basado en el almacenamiento dinámico de calor se asocia con una introducción del aire exterior con temperaturas más bajas durante la noche y las primeras horas de la mañana, como menos afectado por el futuro cambio climático regional. Un impulso ventajoso logrado en el desempeño energético se categoriza a través de las fortalezas y oportunidades. Por lo tanto, el modelo "B" representa la forma del edificio receptivo al clima con un sistema de enfriamiento de confort integrado sensible, lo que ofrece un mayor nivel de eficiencia energética, visto también como un factor adquirido de resiliencia frente a las amenazas estimadas del cambio climático. Tal prototipo de edificio hipotético puede resultar como un contribuyente beneficioso en el proceso actual de despliegue rápido de fuentes de energía renovables en el sector de la construcción regional, observado también desde la perspectiva de la transición energética en curso de la Unión Europea

Selecting a structural system for a building is a complex, multidisciplinary process. No design project is the same; however, there are certain criteria that are commonly true in the initial phase of evaluating different structural schemes. These criteria encompass all aspects of a full, functioning building, forcing the design team to be creative in their approach of satisfying all facets. An investigation was carried out for several structural steel framing options available to designers. The schemes describe how each successfully resist lateral loads explaining the advantages and disadvantages of each. Many of the structural design tools available for initial structural system evaluation are strength based. The demand for cheaper, more efficient and taller structures has paved the way for performance based design. A simple cantilever beam performance based analysis was utilized to evaluate three common structural framing schemes in order to gain a better understanding of the performance of each. Results give recommendations for efficient structural solutions for proposed buildings as a function of height.

In this thesis, the importance of cladding panels on mid-rise buildings in an earthquake-prone region is investigated. A cladding panel acts as a protective or an insulating layer to control weather infiltration. The Northridge Earthquake, which took place on January 17, 1994, caused numerous heavy cladding panels to fall off the walls of residential and commercial buildings. The failure of these panels was a result of an insufficient understanding of the cladding behaviors as a subsystem in the three-dimensional framing system. Cladding is designed to be isolated from the structural frame movement during an earthquake. However, numerous studies have concluded that cladding interacts with the structural frame in providing lateral resistance. The advantages and disadvantages of different cladding materials, cladding systems, and cladding connections are presented in this thesis. The effects of cladding on mid-rise buildings in the Northridge Earthquake in the Los Angeles area are simulated in this study. Motion resistance contributed from cladding in a particular mid-rise building, a 19-story office building in downtown Los Angeles, is investigated. Analyses of clad models and unclad models are carried out, and clad models are discovered to displace less than unclad models. Therefore, cladding is able to contribute lateral motion resistance to a building during an earthquake, and structural engineers should include cladding in their analysis models when designing a building.

During the last few years, the merging of timber building tradition with the application of new technologies has produced new prefabricated building systems in Europe and North America. Mid-rise buildings present a unique opportunity to apply new timber technologies.
Chile has shown sustained growth of buildings construction during the past decades but little further development in the use of wood. To establish the feasibility of timber systems applied to the Chilean context this research considered social aspects, technical aspects and local standards related to the manufacture and construction using timber components. A project proposal is used to analyze the architectural applications of timber systems according to the Chilean context. The design considers the case of densification in the city of Santiago and investigates the possibility of developing mid-rise structures using the structural properties and features of timber systems. So far only two systems applied to mid-rise structures have been tested for seismic resistance on full scale prototypes: Midply and Cross Laminated Timber.
Both systems are suitable for the Chilean context despite their different features. However, it is essential to modify the Chilean Structural Code in order to properly incorporate the seismic performance of timber structures. Also, further research is needed on the application of softwoods and local construction techniques are required for timber panel systems in order to change the negative perception of users about timber housing.
The Chilean context has interesting design opportunities to develop buildings that use prefabricated timber panel systems. These structures are flexible, light and have shear high-resistance. However, it is necessary further exploration on architectural possibilities that could expand the use of these alternatives.

<p>New steel production processes have led to a remarkable improvement in steel products within the last few years, and now allows steels to be produced according to the desired mechanical and chemical properties. High-Performance Steel (HPS) is the designation given to this new generation of steels that offer higher performance not only in terms of strength but also toughness, weldability, cold formability and corrosion resistance, compared to the traditionally used mild steel grades.</p> <p>The development of HPS goes with today's increased demand for slender lightweight structures, as for example in bridge design and the design of high-rise buildings, where there is a strong requirement to use high-strength materials in combination with good execution and fabrication properties. However, on the structural engineering side there is a need for knowledge on these new steel grades, and quite often design codes do not provide sufficient information to fully exploit the advantageous properties of HPS.</p> <p>The present volume provides an overview of the development and application of HPS on an international level. This is done by giving information on, for example, the production process, the chemical and mechanical properties, the relevant design and fabrication standards and on recent research results. Approximately fifteen included examples of realised applications aim to provide detailed information based on existing technical solutions, and to point out the major benefits when using HPS in comparison to mild steels.</p> <p>The document is thus not a monograph but an assembly of contributions from different countries. lt is separated into chapters related to different countries, namely the USA, Canada, Japan and Europe, all of them providing a state-of-the-art report on HPS.</p>

Rome’s building industry shows unprecedented and sustained energy starting in the early third century. The structures of labor that supported this building boom are detailed here using literary and epigraphic evidence. The collapse of forms of dependent labor by ca. 300 BCE coincided with the rise of an urban labor supply characterized by slave- and free-wage labor. We detect signs of significant demographic growth at Rome in this period, and much of this increase was owed to immigrating labor. On the one hand, an active slave market pushed labor to the capital; on the other hand, we see at Rome all the prerequisites for wage-labor, even without direct evidence for wages. It is argued that freely mobile workers formed some significant part of the expansion of the city’s labor supply. The epigraphic corpus relating to the city’s working population in this period also suggests a picture of urban workers of various personal statuses.

International IDEA’s Annual Review of Constitution-Building provides a retrospective account of constitutional transitions around the world, the issues that drive them, and their implications for national and international politics. This seventh edition covers events in 2019. Because this year marks the end of a decade, the first chapter summarizes a series of discussions International IDEA held with international experts and scholars throughout the year on the evolution of constitution-building over the past 10 years. The edition also includes chapters on challenges with sustaining constitutional pacts in Guinea and Zimbabwe; public participation in constitutional reform processes in The Gambia and Mongolia; constitutional change and subnational governance arrangements in Tobago and the Autonomous Region of Bangsamoro; the complexities of federal systems and negotiations on federal state structures in Myanmar and South Sudan; and the drawing (and redrawing) of the federal map in South Sudan and India. Writing at the mid-way point between the instant reactions of the blogosphere and academic analyses that follow several years later, the authors provide accounts of ongoing political transitions, the major constitutional issues they give rise to, and the implications of these processes for democracy, the rule of law and peace.

Although urban living has accounted for being the lifestyle for more than half of the global population since 2010, nearly half are still living in a rural context. As pointed out by the United Nations as a backdrop of the Sustainable Development Goals (SDGs) (2016–2030), at least 1.8 billion people across the world still consumed faecally contaminated drinking water by 2015, 2.4 million lacked access to basic sanitation services such as toilets or latrines, and nearly 1,000 children died every day of preventable water and sanitation-related diarrhoeal diseases. Rural areas fare far worse: children are about 1.7 times more likely to die before their fifth birthday as those in urban areas. About 16% of the rural population do not use improved drinking water sources, compared to 4% of the urban population. About 50% of people living in rural areas lack improved sanitation facilities, compared to only 18% of people in urban regions. Far too many one-off rural on-site public health knowledge transfer projects fail to deliver long-term results. Theoretical understanding may be strengthened among non-governmental organization (NGO) practitioners and volunteers to support project planning, monitoring, and evaluation. Based on public health theories and illustrated by relevant examples, as well as the insights gained from the long-established CCOUC Ethnic Minority Health Project in China, this book introduces how health, emergency, and disaster preparedness education programmes could be organized in remote rural Asia, which could become a useful reference for organizers and volunteers of rural development projects.

As the global population increase, the effects of disasters also increase. However, through improved building codes and other disaster risk reduction interventions, the number of deaths appears to be reducing. International frameworks for reduction and response are being built and an audit of the NHS demonstrated the advantages of an integrated health service. Fact sheets, produced internationally with UK involvement, on several aspects of disaster risk reduction have started to increase awareness of the wide variety of needs, although mental health issues need further research. Not all global disasters with far-reaching consequences are catastrophic in nature. The circumstances of congenital rubella and iodine deficiency show the strengths of international collaboration and the need for high-quality science. This chapter explains disaster risk reduction and sets it in its international perspective, with examples of wide-ranging agreements and frameworks, and their application to the wider UK health service.

Soil-structure interaction (SSI) is for sure one of the most neglected effects in seismic structural design practice. However, many researchers showed that it might notably affect seismic performance results. In fact, the state-of-the-art seismic codes are encouraging including SSI for structures with considerable p-Δ effects and mid to high-rise buildings. In the current research, seismic soil-structure interaction analysis is made for a selected mid-rise reinforced concrete building with several different SSI techniques (models). In order to quantify the effect of SSI on the overall response of the selected structure, the global seismic response within a frame of force-displacement relationship for different earthquake intensities, different SSI mathematical models and different soil categories is presented. Comparing the outcome of the performed analysis it was observed that the structural performance was affected significantly by the foundation system and contributes considerably to the overall structural performance of the selected structure in specific soil conditions. As the results indicate, more code-based recommendations are required for the improvement of the SSI structural seismic design, especially in soft soil cases, where the soil-structure interaction might significantly affect the seismic response of buildings.

There is a significant building stock of the existing low- and mid-rise unreinforced masonry (URM) buildings constructed after World War II in Serbia and neighbouring countries. Numerous buildings of this typology collapsed in the devastating 1963 Skopje, North Macedonia earthquake, causing fatalities, injuries, and property losses, and experienced damage in a few recent earthquakes in the region, including the 2010 Kraljevo, Serbia earthquake and the 2020 Petrinja, Croatia earthquake. These buildings are 3- to 5-storey high, have URM walls and rigid reinforced concrete (RC) or semi-prefabricated concrete and masonry floor slabs, usually with a RC ring beam at each floor level. The paper will provide an overview of seismic retrofitting approaches for these buildings, starting from provisions of design codes which were previously followed in Serbia and former Yugoslavia as well as Eurocode 8 (Part 3). Conventional seismic retrofitting technologies based on RC wall overlays which were applied in past earthquakes, including the 2010 Kraljevo earthquake, will be presented and their advantages and disadvantages will be discussed. Finally, a case study of a building in Kraljevo which was damaged in the 2010 earthquake and subsequently retrofitted, will be presented, including the results of seismic analysis and design solution. The paper should be of interest to engineers and academics interested in seismic retrofitting of masonry buildings.

Maintenance management (MM) is an important function in managing high-rise commercial buildings. In comparison to low-rise and mid-rise structures, commercial high-rise buildings have severe maintenance management deficiencies. According to prior studies, implementing lean in maintenance is a well-known and effective strategy to improve maintenance efficiency. Thus, this study aimed to identify strategies to implement the lean maintenance concept for high-rise commercial buildings in Sri Lanka. Due to the lack of literature on building maintenance in the context of Sri Lanka, a pilot survey was carried out to establish the research problem of the study. Consequently, a comprehensive literature synthesis was conducted revealing building maintenance, lean and lean maintenance. Further, the applicability of lean maintenance in the global context of building maintenance had been reviewed. Consequently, under qualitative research methodology, a case study strategy was adopted. The findings of the study identified the experts ‘perception of lean principles in building maintenance and challenges in implementing lean maintenance in commercial high-rise buildings in Sri Lanka from the selected cases. Lack of knowledge about lean, ineffective tactics, and the absence of standards, regulations, and policies are some of the major challenges to lean adoption in Sri Lanka. Then, experts who have extensive experience in both lean and maintenance were interviewed to identify strategies to address the identified challenges in commercial high-rise buildings in Sri Lanka.

The FRIBAS database collects information on the characteristics of more than 300 buildings located in southern and northeastern Italy. The characteristics comprise age, construction material, storey number and other data such as geometrical features (e.g. shape) and construction details (e.g. roof type, floor types). Such characteristics were inferred based on external and sometimes internal building inspection, combined with information provided by residents. In addition, FRIBAS includes the fundamental frequencies of buildings and foundation soil, estimated empirically using single station ambient noise measurements. The database was assembled based on data collected separately in northeastern and southern Italy on different building types (including both low to mid-rise historical and modern masonry and low to high-rise reinforced concrete buildings). The buildings were chosen also based on the possibility of accessing the interior and performing measurements. Data were harmonized into 37 fields which provide a generalized classification of building and soil parameters. FRIBAS is the first database that collects several buildings characteristics, including structural and geometrical features, together with the fundamental frequencies of buildings of and foundation soil. FRIBAS was assembled with the specific purpose of analyzing how different building parameters influence structural behavior (in particular, the fundamental period). The database is available online in open access mode under the CC 4.0 license. The collected data support the definition of different period-height relationships based on construction material and soil types. The analysis can be extended to other parameters associated with specific building types. We discuss the relevance of empirical building and soil characterization for seismic damage/risk assessment and propose potential applications of the FRIBAS database.

Rapid depletion of natural resources and increased environmental degradation demand a vigorous scrutiny of accepted design and construction methods. For more than ten years, New York City has promoted energy efficiency policies—including PlaNYC and the Greener, Greater Buildings Plan—that will radically reshape the education of architects toward energy performance in buildings, reduction of emissions, and the efficient use of resources. Our series of undergraduate studies investigates the relationship between the building form and energy performance, using form-finding algorithms based on solar radiation to shape mid-rise housing typologies for New York City. Currently funded by the Institute of Design and Construction Foundation, we have been exploring the important environmental design opportunities that exist within building envelopes, particularly in residential buildings that are responsible for most of the greenhouse gas (GHG)emissions and power consumption. By integrating and extending current solar technologies such as photovoltaic (PV) and solar thermal (ST) for the predominantly vertical infrastructure of the city, this research targets innovative building mass and surface strategies that are highly energy efficient, generateon-site renewable energy, and produce a new vocabulary for sustainable construction. As part of the initiative, we have also formed an international exchange program between our two institutions to share content and expertise.

<p>NHNY Via Verde is a global model of sustainable housing development. Located in a Bronx brownfield, the 294,000 SF structure contains 222 residential units with 40,000 SF of green roofs and open space. Cascading buildings surrounding a central courtyard consists of a 21 story tower, 16- to 7-story midrise and 5 to 3-story low-rise. Interconnected, accessible green roofs provide continuous access from the courtyard to 12<span>th</span> level roof: the “via verde” or “green way”. Primary structure consists of cast-in-place concrete at the tower and concrete masonry bearing walls with precast concrete plank at mid- and low-rises. These conventional materials are arranged in unconventional ways to maximize efficiency, generating the architectural unit layout from optimal plank spans and eliminating façade bearing walls for prefabricated façades with sunshades and balconies. Secondary structural steel framing supports low rise storefronts, extensive roof PV panel arrays and a rainwater catchment system. Fly ash replacement was maximized in all concrete, and the time effect on strength gain was managed in construction. The large building volume required internal building separations with three independent structures engineered for drift compatibility. Foundation pile capacities vary to optimize efficiency to wide-ranging building heights.</p>

This report presents a wave method to be used for the structural identification and damage detection of structural components in bridges, e.g., bridge piers. This method has proven to be promising when applied to real structures and large amplitude responses in buildings (e.g., mid-rise and high-rise buildings). This study is the first application of the method to damaged bridge structures. The bridge identification was performed using wave propagation in a simple uniform shear beam model. The method identifies a wave velocity for the structure by fitting an equivalent uniform shear beam model to the impulse response functions of the recorded earthquake response. The structural damage is detected by measuring changes in the identified velocities from one damaging event to another. The method uses the acceleration response recorded in the structure to detect damage. In this study, the acceleration response from a shake-table four-span bridge tested to failure was used. Pairs of sensors were identified to represent a specific wave passage in the bridge. Wave velocities were identified for several sensor pairs and various shaking intensities are reported; further, actual observed damage in the bridge was compared with the detected reductions in the identified velocities. The results show that the identified shear wave velocities presented a decreasing trend as the shaking intensity was increased, and the average percentage reduction in the velocities was consistent with the overall observed damage in the bridge. However, there was no clear correlation between a specific wave passage and the observed reduction in the velocities. This indicates that the uniform shear beam model was too simple to localize the damage in the bridge. Instead, it provides a proxy for the overall extent of change in the response due to damage.

The current COVID-19 epidemic is both a health and societal issue; therefore, groups historically excluded and marginalised in terms of healthcare will suffer if COVID-19 vaccines, tests, and treatments are to be delivered equitably. This rapid review is exploring the social and cultural challenges related to the roll-out, distribution, and access of COVID-19 vaccines, tests, and treatments. It highlights how these challenges impact certain marginalised groups. Case studies are taken from sub-Saharan Africa (the Democratic Republic of Congo, South Africa), with some focus on South East Asia (Indonesia, India) as they have different at-risk groups. Lessons on this issue can be learned from previous pandemics and vaccine roll-out in low- and mid-income countries (LMICs). Key points to highlight include successful COVID-19 vaccine roll-out will only be achieved by ensuring effective community engagement, building local vaccine acceptability and confidence, and overcoming cultural, socio-economic, and political barriers that lead to mistrust and hinder uptake of vaccines. However, the literature notes that a lot of lessons learned about roll-out involve communication - including that the government should under-promise what it can do and then over-deliver.

The article is based on three cases of private psychoanalytic work with successful businessmen from central and northern parts of Ukraine. The research methodology was psychoanalytic theories devoted to the unconscious meanings of money and the role of money in the psychoanalytic setting, including object theory, drive theory, psychosexual development theory, narcissism theory, Oedipus complex, transference and resistance. What presents the interest of this study are the cases when those who grew up in poverty finally obtains such a desired object — money, wealth, however, something unconscious hinders this person to get satisfied by it and even to admit obtaining it. The presented clinical work was conducted as classic psychoanalysis in person with different duration: 5, 10 and 46 months. Men were asked to tell whatever comes to mind: thoughts, memories, dreams, phantasies, feelings etc. The role of psychoanalyst was to hear specific connections between patient’s stories and to analyze them together with the patient. The cases presented highlight several psychological features of young men «millionaires» who suffer from their own success. 1. Sensitivity to Father’s (real or symbolic) acceptance of their business and financial success. 2. Activation of unconscious Oedipus complex and Complex of castration because of the risk to dethrone the Father in reality, with experiences of guilt, fear and expectation of punishment. 3. Projection of their own envy, hate, wish to avenge and killing phantasies into external objects (friends, partners, psychoanalyst) with building individual defensive strategies from them. These psychological features were associated not only with suffering and psychopathological symptoms but also with impossibility to continue business development. In addition, the cases analyzed in the article show some difficulties in building business connected with the generations gap. Fathers from the USSR or the 90s teach their sons to act in the way that is not relevant for successful careers nowadays. This latent or manifested struggle between generations may be an important factor in abovementioned psychological features.
