This document discusses seismic analysis of multistory buildings built on soft ground using time history analysis. It reviews past seismic failures of open ground story buildings and the need to analyze the seismic response of such structures. The methodology involves modeling a sample 9-story reinforced concrete building with and without infill walls at the ground level using time history analysis in software. The analysis aims to observe the effects of different support conditions and infill wall modeling on the seismic response of the open ground story structure.
