Abstract:
In India the enormous loss of life and property perceived in the last couple of decades, attributable to failure of structures instigated by earthquakes. Responsiveness is now being given to the assessment of the sufficiency of strength in framed RCC structures to resist solid ground motions. The seismic reaction of RCC building frame in terms of performance point and the earthquake forces on Reinforced building frame with the help of pushover analysis is carried out in this project. In this method of analysis a model of the building is exposed to a lateral load. Pushover analysis can afford a substantial insight into the weak links in seismic concert of a structure and we can know the weak zones in the structure. In this project effort has been made to investigate the effect of Shear Wall and Structural Wall on lateral displacement and Base Shear in RCC Frames. RCC Frames with G+13 are considered, one with soft storey and other with normal building in L- shape. The pushover analysis of the RCC building frame is carried out by structural analysis and design software ETABS.

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:
Steel-concrete composite constructions in Bangladesh are nowadays very popular owing to their advantages over conventional concrete and steel constructions. Concrete structures are massive and allot more seismic weight and less deflection whereas steel structures instruct more deflections and ductility to the structure, which is beneficial in resisting earthquake and wind forces. Composite construction combines the better properties of both steel and concrete along with lesser cost, speedy construction, fire protection etc. The objective of this study was to analysis and design ground floor plus 19 storied R.C.C, Steel and Composite (steel-concrete) multi-storied parking structure’s frame of same plan using ETABS 2013 software and compare their structural parameters with estimated cost for required material. All frames are designed for same gravity and dynamic loadings. The RCC deck-slab is used in steel and composite frame. Beam and column sections are made of RCC, steel or steel-concrete composite sections. The composite construction option provided about 25 % and 18% less cost when compared to RCC and steel structure, respectively. Comparative study concludes that the composite frames are best suited among all the three types of constructions in terms of material cost and benefit added with better structural behaviour.

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 advancement in construction field is increased day by day. The numbers of buildings, height of building is increased. The effect of lateral load is increased with respect to the increase of height. Advance construction methods and structural systems are to be introduced to enhance the structural safety. There are different types of structural systems which are to be used to resist the effect of lateral loads on the buildings. tube, bundled tube, tube in tube, and tube mega frame structures tubular structures. A tube-in-tube structure Comprises of a peripheral framed tube and a core tube interconnected by floor slabs. The frame tube structure takes more of lateral load the efficiency of this system is derived from the great number of rigid joints acting along the periphery, creating a large tube. In which the horizontal slabs and beams connecting vertical elements are assumed as continuous connecting medium having Equivalent distributed stiffness properties. The tube-in-tube structure with central tube provides stability against lateral loading as well as gravity loading. The Static analysis is use for analysis of tubular structures and the output of the models are evaluate to have a comparative study of their wind performance in different terrain, Also, this system provides enough opening for stairways, elevators and ducts etc. It is suitable for high rise structure. The use of tube-in-tube structure allows speedy construction. It is suitable for RCC, constructions. This study is focused on wind behavior of tube in tube structure for varying terrain category in India for the parameters like wind displacement, story drift, and time period.

Abstract:
The present decade, high rise multi-storey buildings are subjected to many external effects such as earthquake, wind loads, tidal loads, etc., in most cases high rise buildings have more vulnerable to earthquake and wind loads. Most of the reinforced concrete multi-storeyed frame buildings were heavily damaged and many of them completely collapsed during due earthquakes. RC frame buildings were severely damaged due to various deficiencies when proper codal provisions are not designed. A study is need to study the behaviour of the RC framed structure under earthquake load to reduce the damage caused by earthquake forces In this investigation a RC framed building of G+20 storeyed is considered in several seismic zones under different soils as per Indian Standard code IS 1893(part1):2016, using STAAD.

Abstract:
The major purpose of this study is to justify construction method of a hybrid structure in core area with construction complexity due unsafe excavation conditions and tries to define its rigidity and strength. Both RCC and Frame structure transfer same load to ground through foundation but the transfer mechanism varies. In some practical condition, building construction should be carried out in compact areas with unsafe adjoining building where adequate excavation for foundation cannot be carried out. In such cases, one bay hybrid structure is proposed for construction with combined RCC frame structure and load bearing walls. In these combined cases, both structures works as same unit to transfer building load but the transfer pattern varies. The variable load transfer pattern is due to discontinuity in structural system which also effect on seismic response of the building. The placement of a masonry load bearing structure in RCC frame structure varies design of all structural components of the building. To study actual behavior of hybrid structure in various load condition and introducing cost minimization techniques of buildings structural analysis was carried using ETABS 2016 with composite structural arrangement and with induction of load bearing wall as structural component. By which seismic behavior of building in both cases was obtained as well as reduction in rebar percentage and dimensional reduction of structural components can be achieved.Journal of the Institute of Engineering, 2017, 13(1): 117-124

Abstract:
Negli ultimi anni sono state sviluppate varie soluzioni tecniche per la progettazione sismica di strutture. Questa ricerca sviluppa un metodo di confronto basato sull'analisi di costi di costruzione e danni causati dal sisma. Il metodo viene applicato al caso di studio della scuola di Bisignano (CO, Italia). L'edificio è stato progettato conformemente alle NTC 2008 con approccio tradizionale e combinando il contributo di dissipatori viscosi e dissipazione isteretica. Le strutture vengono poi analizzate sotto diverse condizioni sismiche al fine di calcolare i costi di riparazione attesi e comprendere quale soluzione tecnica risulti più economicamente vantaggiosa a parità di azione sismica di progetto.

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:
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.

Abstract:
In every part of the world earthquakes are very common. Geographical figures of India show that almost 54% of the land is at risk to earthquakes. A report by the World Bank & United Nations estimates that about 200 million city inhabitants in India will be exposed in few years to earthquake. Due to the earthquakes, excessive destruction of infrastructure and buildings can be caused. Increasingly, the non-linear analysis are a popular and relatively new and powerful way for seismic performance evaluation of new and existing building structures. Persistent hard work to resolve the variances between the actual observed performance and the expected performance of building structures is needed. It is expected that on the structural system and its components, the pushover analysis will provide sufficient data on seismic demands imposed by the design ground motion. The main objective of present study is to find the performance of building structure under earthquake using performance based seismic design analysis. Nonlinear (Pushover) static analysis is method to evaluate the performance level of building. In this report, pushover analysis is carried out for a 9 stories building situated in ZONE IV to check the seismicity effect and performance level of a building by SAP2000. Pushover Analysis produces a Pushover curve consists of capacity spectrum, demand spectrum and performance point.

Abstract:
A high-rise building whose first floor is composed of open spaces is called a soft floor building. Such floors have a substantial impact on a building's seismic performance. this is awing to the floors abrupt lateral stiffness and strength fluctuations. A large earthquake can cause enormous damage or collapse of a building. Previous studies have shown that structure damage from earthquakes is the cause of large displacements. If the structure, is intended for horizontal loads, the structure will show greater deflection. Braces and shear walls are the most common lateral load-bearing systems for reducing displacement. Shear walls and braces are used for improving lateral stiffness, ductility, minimal lateral displacement, and safety. Story drift and lateral displacement are essential considerations in seismic design of structures. shear wall was added inside the proposed structure to counter the lateral load induced by earthquake and to improve structure's stiffness. Therefore, by making use of shear walls in the building, it is possible to prevent large displacements and thus damage due to displacements. In addition, Bracing is also mainly used foe structures exposed to wind and seismic loads. It resists the forces of the bracing element in both compression and tension. As a result, the brace system withstands horizontal loads very efficiently. The brace frame makes the system more efficient and stiffens the structure laterally. By adding material to the bare frame, it forms an efficient structure for higher heights. In this thesis work, the seismic response of soft-floor RCC building is studied using seismic analysis method. the parameters considered in this study include soft floor heights, shear wall position, bracing types and arrangements along the height of the building. Furthermore, the effectiveness of using simple strengthening procedures to increase structural safety will be investigated without causing large changes tot he building's architectural and functional needs will be studied

Abstract:
The dynamic soil-structure interaction effects for RC framed buildings with or without shear wall on raft foundation is evaluated by explicit consideration of structural nonlinearity and soilstructure interaction as per Indian and Ethiopian seismic codes. In the current study, the finite element model (Elastic continuum approach) employed for soil-foundation-structure model. Hence, four and eight number of stories with or without shear wall on raft foundation found on rock, dense, stiff and soft soils are designed and modeled using SAP 2000 v 21. The building studied with or without incorporation of SSI effect. The analysis is carried out in 3 stages: (1) response spectrum analysis, (2) soil-structure interaction analysis, and (3) nonlinear structural analysis (pushover analysis). The response spectrum analysis is used to design the section sizes of the members and a comparison is made according to IS 456: 2000 and ES EN-2. The nonlinear static pushover analysis is used to observe proper structural behavior for defined push displacement. The resulting pushover curves are studied through performance-based design (PBD). Finally, a comparison is made between the behavior of each building in the fixed base condition and SSI condition. This work demonstrates ES ES-2 moments exceed that of the IS 456: 2000 by an average of about 15.58% for beam area of tension reinforcement for span and 15.4% for support. So, Indian code provides a more economical design than Ethiopian code ES EN-2. Moreover, the nonlinear response of buildings was determined and compared between two cases: fixed-base and SSI conditions. Response quantities such as SSI effects on the target displacement, SSI effects on the story drifts, SSI effects on the plastic hinge mechanisms and rotations obtained from pushover analysis of superstructure. The numerical findings indicate that incorporating the soil-structure interaction generally increases the top displacement and plastic hinge rotation, reduces the base shear. Hence, it is very important point is that soil-structure increases the plastic deformation.

Abstract:
Abstract Fatigue is a phenomenon identified as a significant degradation mode which affects industrial facilities, in particulier the lifespan of nuclear power plants. As one of its important branches, the environmentally assisted fatigue (EAF) considers not only effects of unfavorable mechanical and thermal conditions, but also PWR primary water environment in nuclear components. This phenomenon can accelerate fatigue related structure failure for common materials in nuclear components such as austenitic stainless steels and nickel-based alloys. Within this frame of reference, the RCC-M code formulated by AFCEN has included probationary phase rules named RPP-2 and RPP-3. EDF and CNNC/NPIC have hence established a specific collaboration on environmentally assisted fatigue to contribute to validation and improvement of these rules in the RCC-M code. Part 1 of the paper states the context of the collaboration between EDF and CNNC/NPIC and the methods used by each side. Part 2 presents the satisfactory results of code comparison based on the AFCEN-provided benchmark case. As the third part, this paper presents the comparison based on an industrial case close to an HPR1000 nozzle under pressurized thermal shock (PTS) provided by CNNC/NPIC, where the RCC-M code is applied in a situation equivalent to the engineering practice. By following the methodology of the Part 2, EDF and CNNC/NPIC use respectively their proper tools code_aster POST_RCCM and FAC_NPIC to calculate the cumulative fatigue usage factor with or without considering the effect of EAF following the comparison between RCC-M RPP and NUREG/CR-6909 rev.1. The comparison focuses on the technical details of transient combination method and temporal discretization of transients. Analysis concerning pressurized thermal shock type transients is also discussed. Comparisons show some differences between the results of the two parts. Some could be attributed to the various calculation processes between EPRI Guidelines and RCC-M RPP-3. Minor differences could be attributed to engineering practices like thermal time stepping.

Abstract:
AFCEN is a French Standard Development Organization which publishes codes for design, construction and in-service inspection rules for Pressurized Water Reactors. The fields covered by theses codes are mechanical components, in-service surveillance of mechanical components, electrical equipments, nuclear fuel, civil works and fire protection. AFCEN was initially founded by electric utility EDF and nuclear steam supply system manufacturer FRAMATOME. AFCEN has more than 60 institutional members, representing more than 650 experts who contribute to the development and continuous improvement of codes. The RCC-C code, which is dedicated to PWR fuel assemblies and associated core components, set forth generic requirements to be fulfilled by the suppliers and by the manufacturers for the design justifications and for the manufacturing and inspection operations of PWR fuel assemblies and rod cluster control assemblies. The RCC-C is intended to be used in the frame of contractual relations between a customer (nuclear operator) and a nuclear fuel supplier. The first edition was published in 1981. Over the years, many changes have been made to the original text but the structure hasn’t been much modified. Because of this, the text was becoming less coherent for the users and was lacking also minimal explanations. A redesign of the code was scheduled for the 2015 edition to address those problems. With the involvement of fuel vendors FRAMATOME, WESTINGHOUSE, and French nuclear operator EDF, the text was restructured and clarified. New requirements were implemented and the set of both design and manufacturing rules was strengthened to reflect fuel vendors’ practices and operator expectations. This article explains the main modifications that were implemented since the 2015 edition, and also outlines the prospects for future changes taking into account the latest regulatory requirements and evolutions of the industrial practices.

Full text
Abstract:
One of the main nuclear materials is the austenitic stainless steels, which have good ductility and toughness, high thermal expansion coefficients and a thermal conductivity lower than that of martensitic or ferritic steels. The 316L(N) austenitic stainless steel (X2CrNiMo17-12-2 with controlled nitrogen) is evaluated for structures such as the vessels, which are steel enclosures surrounding the reactor core and its assemblies, in fourth generation nuclear systems. The RCC-MR code, which is used as a frame of reference in the manufacture of SFR (Sodium Fast Reactor concept), recommends the use of austenoferritic filler material for the welding of 316L(N) steel. These recommendations derive from past experience of working with fast neutron reactors (Phenix and Superphenix). In order to guarantee long-term properties at high temperatures, an austenoferritic and an austenitic filler metals are evaluated as filler metals. However, these materials are susceptible to hot cracking. Therefore, a study is conducted to ensure their weldability. The purpose of this work is to evaluate the susceptibility to hot cracking of the studied materials and to present a methodology applied to define a criterion called “laboratory” for each material and its transfer to a structure test. The relative susceptibility to hot cracking of these materials was evaluated using four tests: the Varestraint, the Gleeble, the trapezoid and the skew tests. Numerical simulation using Cast3M code and Sidolo software of these four tests were investigated in order to survey behavior laws of each studied material and solidification cracking thermomechanical criteria intrinsic to the materials. Some test and simulation results as well as hot cracking susceptibility ranking are presented and the transferability to real component welds of hot cracking criteria is discussed.

Abstract:
This paper describes an experimental study to extract the dynamic characteristics of a two-storey reinforced concrete (RC) frame structure using piezo-electric ceramic (PZT) patches. PZT patches were embedded in the structure at the time of construction. Basically two techniques were applied to monitor the health of structure, the global dynamic technique and the local electro-mechanical impedance (EMI) technique. Global dynamic technique, which is based on frequency changes, is effective in low frequency range only. Due this limitation, initial damage/hair crack can not be detected by the global dynamic technique. On the other hand, EMI technique acts at higher frequency range and is very sensitive to detect the initial damage/hair cracks. The lower natural frequencies of the frame structure were determined experimentally using global techniques. The two-storey R.C. frame was modeled using ANSYS 9.0 to determine the frequencies numerically. Experimental results were compared with numerical results, which were found to be agreeable. Initial cracks were detected by the EMI technique. Severity and location of damage can be also determined with the help of these parameters. Inputs were chosen from these parameters to train an artificial neural network (ANN) whose outputs were the severity and the location of damage. Thus, complete monitoring can be done by the combination of global vibration and EMI technique using PZT patches. This integrated approach can be used for damage/crack detection at very early stage. This approach is very sensitive and cost effective to predict the incipient damages in civil structures.

Full text
Abstract:
To effectively improve the ability of frame structures to comprehensively defend against seismic collapse and progressive collapse, this paper proposes a novel configuration, kinked steel plate (KP). The mechanical properties of KP were studied through test and numerical simulation. It is found that when KP is in tension, the resistance that can provide in the small deformation stage is lower, but it can provide a resistance equivalent to that of ordinary straight steel plates after being straightened. When KP in compression, the resistance that can provide is very small and can be ignored. Then, the application of KP in steel frame and reinforced concrete (RC) frame structure was discussed. For the application of KP in steel frames, KP is combined with the reduced beam section (RBS) connection, which can obtain an innovative connection (RBS-KP) containing KP. For the application of KP in RC frame, KP is added to RC beams, and a new type of RC beam containing KP is proposed. The seismic and progressive collapse performances of the RBS-KP connection and the new type of RC beam were studied by numerical simulation. Results illustrate that the RBS-KP connection has comparable seismic performance and greater resistance against progressive collapse than the RBS connection, as is the new type of RC beam relative to the RC beam.

LOAD TRANSFER MECHANISM OF STEEL GIRDER-RC PIER CONNECTION IN COMPOSITE RIGID-FRAME BRIDGE. The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.286.

Full text
Abstract:
The composite rigid-frame bridge, where the steel girder and the reinforced concrete (RC) pier are rigidly connected, has a high bearing capacity and superior long-term performance. The steel girder-RC pier connection is the critical detail for the design of such a structural form. To this end, a detailed review of composite rigid-frame bridges in China and abroad was carried out to summarize various forms of connections and evaluate their applicability. A novel connection type was then proposed to improve the connective performance between steel plate girders and RC piers. Threedimensional finite element models were further developed to investigate the force transfer mechanism, accounting for the impact of concrete stress, shear force in the connectors, and stress of steel plates. The results indicated that the proposed connection was capable of transmitting external loads reliably, and its ultimate bearing capacity exceeded design loads. The shear force of perfobond connectors, the tension of reinforcement, and the bearing effect of the bottom flange provided the major force transmission path to resist the external load.
