Dynamic analyses for residential building in zone 2 and 5

Abstract

This study focuses on the dynamic (seismic) analysis of residential buildings situated in seismic Zones II and V, as defined by the Indian seismic code IS 1893:2016. Zone II represents areas of low seismic activity, while Zone V experiences the highest seismic risk in the country. The primary objective is to evaluate the structural behaviour of residential buildings under varying seismic conditions using dynamic analysis methods, including response spectrum and time-history analyses. These methods help assess critical parameters such as natural frequency, mode shapes, base shear, inter-story drift, and displacement.
