Case Study on a Structural Building Subjected to Earthquake Forces Considering Soil Structure Interaction

Abstract

In recent years India has been considered as one of the disaster prone countries in the world. Studies are carried out to study the seismic behavior of the structure when hit by an Earthquake. The course of tremor depends upon the type of soil and varying topographical region which are classified under various seismic zones i.e. II, III, IV, V. Past researchers revealed that the vertically irregular structures are mostly prone to Earthquake damages. In this paper, attempt has been made to study the effects of vertical irregularities on a structural building and seismic behavior of the structural building during an earthquake. The structural model considered has been already constructed in Earthquake prone area: - Sikkim, India, which falls under seismic zone [IV]. The structure was modeled and analyzed by Response Spectrum analysis considering soil structure interaction using E-tabs software.
