The objective of this investigation is to evaluate the FEMA-356 Nonlinear Static Procedure (NSP), the Modal Pushover Analysis (MPA) procedure, and the "Sum-Difference" procedure using recorded motions of a building that was damaged during the 1994 Northridge earthquake. For this purpose, displacements and drifts from these procedures are compared with the values "derived" from the recorded motions. It is found that the FEMA-356 NSP and the "Sum-Difference" procedure typically underestimates the drifts in upper stories when compared to the recorded motions. Among the four FEMA-356 distributions considered, the "Uniform" distribution led to the most excessive underestimation indicating that this distribution may be unnecessary. The MPA procedure, in general, provides much-improved estimates of the response 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.
