The objective of this study was to verify the adequacy of the proposed Seismic Performance Factors for the newly developed Cold-Formed Steel Special Bolted Moment Frames in the AISI S110 Seismic Standard. The FEMA P695 methodology, Qualification of Building Seismic Performance Factors, was used for this purpose. A total of 13 archetype designs, representing two seismicity and two gravity load levels, were designed and analyzed. The computed results from all individual archetypes and four performance groups showed that the proposed seismic performance factors met the acceptance criteria and could provide a sufficient margin against collapse under the maximum considered earthquake.
