125. Seismic Performance and Resilience Comparison of Three Designs of a Hypothetical 6-Story Steel Building in Los Angeles: Special Moment Frame (SMF), Base Isolated SMF, and SMF with Viscous Dampers

This paper studies the seismic performance and resilience of three different designs of a hypothetical six-story steel building located at a near-fault site in Los Angeles, California. The three lateral seismic resistance systems evaluated satisfy the requirements of ASCE 7-22 and are: (i) fixed-base Special Moment Frame (SMF or FB-SMF); (ii) SMF base isolated with triple friction pendulums isolators (BI-SMF); and (iii) SMF with fluid viscous dampers (SMF-VD). All three buildings are designed to satisfy the minimum requirements of ASCE 7 for a Risk Category II building.
