STUDY THE BEHAVIOUR OF HIGH RISE BUILDING AT DIFFERENT POSITIONS OF SHEAR WALLS SUBJECTED TO SEISMIC LOADING

Abstract

This study presents the procedure for seismic performance estimation of high-rise buildings based on a concept of the capacity spectrum method. In 3D analytical model of 22 storied buildings have been generated regular buildings Models and analyzed using structural analysis tool ETABS. The analytical model of the building includes all important components that influence the mass, strength, stiffness and deformability of the structure. To study the effect of concrete core wall & shear wall at different positions during earthquake, seismic analysis using both linear static, linear dynamic and non-linear static procedure has been performed. The deflections at each storey level have been compared by performing Response spectrum method performed to determine capacity, demand and performance level of the considered building models. From the below studies it has been observed that non-linear Response spectrum method provide good estimate of global as well as local inelastic deformation demands and also reveals design weakness that may remain hidden in an elastic analysis and also the performance level of the structure. In this study was conducted for G+21 story building to check the deflection, Building shear, Bending and building torsion by using Response spectrum method under influence of shear walls.
