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

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Different performance of bearing walls 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 system and building frame system designed as ordinary and special shear walls. Performance of the model walls are evaluated through static pushover and incremental dynamic analyses. Results show the superior performance of bearing wall system, which shows justification for possible increase in the response modification factor of this sytsem in the design codes.
