Evaluation of Seismic Collapse Performance of Steel Special Moment Resisting Frames Using FEMA P695 (ATC-63) Methodology
This paper summarizes a study focused on evaluating the collapse performance of steel Special Moment Frames (SMFs) by application of the FEMA P695 methodology. In this study, archetypes that comprise 3-bay special SMFs and serve as lateral load resisting system of buildings ranging from 1 to 20 stories are designed using ASCE 7-05 and AISC 341-05 provisions. Nonlinear models are developed using recent advances in structural component modeling, with structural component parameters extracted from a steel component database. These models are analyzed to predict the collapse capacity of each design, and the adjusted collapse margin ratios (ACMR) are evaluated and compared to acceptance criteria. It was found that SMFs designed in accordance with present seismic provisions provide an acceptable margin of safety with the exception of a performance group that contains tall moment resisting frames designed for high seismic zones using the response spectrum analysis procedure.
