THA of Building in Various Earthquake Zones: A Review

Abstract

In accordance with Indian Standard standards, this research utilizes STAAD-PRO software to perform a time history analysis of structures in Earthquake Zones II, III, IV, and V. The primary objective is to assess structural resilience and seismic performance across varying seismic intensities to guide earthquake-resistant design strategies. Buildings exposed to both artificial and actual earthquake ground motions are modeled for each seismic zone, with key structural performance indicators such as displacements, base shear, and natural frequency fluctuations evaluated. The analysis of 12 models reveals that horizontal displacement is the dominant factor influencing overall movement, while vertical displacement varies between design configurations. Additionally, increasing horizontal forces significantly impact torsional moments, affecting the structural stability of buildings. This study further investigates the role of axial and vertical forces in structural behavior, emphasizing the impact of load variations and design modifications. The findings provide valuable insights into optimizing seismic-resistant structural design across different earthquake zones.
