Performance of Flat Slab Structure Using Pushover Analysis

Abstract

Performance Based Seismic Engineering is the modern approach to earthquake resistant design. It is a limit-state based design approach extended to cover complex range of issues faced by structural engineers. Flat slabs are becoming popular and gaining importance as they are economical as compared to beam-column connections in conventional slab. Many existing flat slabs may not have been designed for seismic forces so it is important to study their response under seismic conditions and to evaluate seismic retrofit schemes. In this paper we have discussed the results obtained by performing push over analysis on flat slabs by using most common software SAP2000. A (G+7) frame having 5 bays is considered for analysis. It is observed that the performance point of flat slab is more as compared to conventional building.
