Analysis and Design of Shear Walls for Earthquake Resistant Buildings Using ETABS

Abstract

The approach for estimating the seismic performance of tall structures is presented in this paper and is based on the idea of the capacity spectrum technique. Thirty-story structures have been analysed using the structural analysis programme ETABS, with normal and irregular building models created in 3D. Every significant element that affects the building's mass, strength, stiffness, and deformability is included in the analytical model. Through the use of linear static, linear dynamic, and non-linear static procedures, seismic analysis has been carried out in order to examine the impact of the concrete core wall and shear wall at various points during an earthquake. The Response Spectrum Method was used to examine the deflections at each storey level in order to ascertain the capacity, demand, and performance level of the building models under consideration. According to the research listed below, the non-linear Response spectrum technique yields accurate estimates of both local and global inelastic deformation demands. It also identifies design flaws that would go unnoticed in an elastic analysis and the structure's performance level. Storey drifts are discovered using the Response spectrum approach within the limits given by code (IS: 1893-2002).
