Evaluation of Current Nonlinear Static Procedures Using Strong Motion Records
This paper evaluates the current Nonlinear Static Procedures (NSPs) specified in the FEMA-356, ATC-40, and FEMA-440 documents using motions of a reinforced-concrete building that was strongly shaken during the 1994 Northridge earthquake. For this purpose seismic demands — peak roof displacements, floor displacements, and inter-story drifts — estimated from the NSPs are compared with the values "derived" from recorded motions. It is shown that the Capacity Spectrum Methods in ATC-40 and FEMA-440 documents may significantly underestimate the seismic demands. The Coefficient Methods in FEMA-356 and FEMA-440 documents, on the other hand, lead to much better estimates of seismic demands compared to the values "derived" from recorded motions.
