Seismic Design Factors for Steel Moment Frames with Masonry Infills: Part 2

In this second part, archetypical steel moment frames with masonry infills are evaluated using the ATC-63 methodology, which is a systematic procedure for the determination of seismic design factors of structural systems. The ATC-63 methodology is briefly reviewed. Procedures in the ATC-63 methodology are specialized for application to infilled steel moment frames. Results from the ATC-63 evaluation of the archetypical infilled steel moment frames are presented, and are used to propose seismic design factors and design guidelines for steel moment frames with masonry infills. The applicability of the proposed seismic design factors and guidelines for reinforced concrete infilled frames is discussed.
