COMPARATIVE STUDY ON PODIUM STRUCTURE AND NORMAL STRUCTURE UNDER SEISMIC BEHAVIOUR

Abstract

This study investigates the Earthquakes are natural hazards which cause destructionto life and property. The
placement of beams and columns of the podium are very important under both static and dynamic analysis. In this study
attempt is made to understand the effect of responsespectra (Dynamic analysis), Static analysis and a time history
analysis with 3 different time history Bhuj, chamoli and Uttarkashi taking for study. Present study includes four different
podium structure and compare the base shear, storey stiffness, storey displacement short column effect with their normal
structure under both the dynamic and static analysis, earthquake data is used as an input motion for different modes to
get an acceleration time history of the building as well as response spectra. ETABS was used to perform response
spectra and time history analysis. Total 5 models were analyzed like 4 different column placed structure and one normal
structure.
