Investigating The Seismic Response of Structural Walls Using Nonlinear Static and Incremental Dynamic Analyses

Abstract

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special structural walls. Performance of the model walls are evaluated through static pushover and incremental dynamic analyses. Results show superior performance of the bearing wall system, which is in odd with small response modification factor given in the current design codes.
