This study highlights the importance of explicitly recognizing the presence of the floating column in the analysis of building. The earthquake forces developed at different floor levels in a building need to be brought down along the height to the ground by the shortest path, any deviation or discontinuity in this load transfer path results in poor performance of the building. The RCC building models having (G+7) storey without floating columns and with floating column at each storey level, alternate location are considered for the study. The response spectrum analysis and pushover analysis of building is carried out using structural engineering software SAP 2000 and the seismic performance of building with various floating columns location is compared with respect to various parameters.

Keywords: Floating columns, response spectrum analysis and pushover analysis
