Sesimic Evaluation Of Multistoried Building With Ground Soft Story And With Infills By Using Etabs
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2016, Vol 4, Issue 2
Abstract
Recent building codes for seismic design and evaluation in Europe and American feature performance based criteria that entail the estimation of inelastic response of the building due to seismic. These seismic demands can be accurately determine by employing methods of nonlinear time history analysis. Simplified methods based on nonlinear static analysis, known as pushover analysis method and linear dynamic analysis, known as time history analysis method, have been developed by several regulations to satisfy the performance based criteria for seismic design and evaluation of buildings. This thesis deals with multistory buildings with open (soft story) ground floor are inherently vulnerable to collapse due to seismic loads, their constructions is still widespread in develop nations. Social and functional need to provide car parking space at ground level far outweighs the warning against such buildings from engineering community. In this study, 3D analytical model of multistory building have been generating for multistoried building model and analyzing using structural analysis tool ‘ETABS’. To study the effect of models with ground soft and infill's during earthquake, seismic analysis both linear static(response spectrum method) , linear dynamic analysis(time history analysis) as well as non linear static(pushover method) procedure have to be perform. The analytical model of building includes all important components that influence the mass, strength, stiffness of the structure. The deflections at each story have to be compare by performing equivalent static, response spectrum method as well as time history analysis also be perform to determine capacity, demand and performance level of the considering models. Numerical results for the following seismic demands considering the inelastic behavior of the building, ductility coefficients of structures.
