Abstract

The objective of this investigation is to evaluate the FEMA-356 Nonlinear Static Procedure (NSP), the Sum-Difference procedure, and the Modal Pushover Analysis (MPA) procedure using recorded motions of buildings that were damaged during the 1994 Northridge earthquake. It is found the FEMA-356 NSP and the Sum-Difference procedures typically underestimates the drifts in upper stories and overestimates them in lower stories. The MPA procedure provides estimates of drifts that are better compared to the FEMA-356 NSP and the Sum-Difference procedure. In particular, the MPA procedure is able to capture the effects of higher modes.
