AISC Research: Seismic Evaluation and Retrofit of Concentrically Braced Frames [H3]

Prior to around 1988, concentrically braced frames (CBFs) used for seismic lateral force-resisting systems were not designed to promote ductile response using capacity-based design of the braced-frame beams. AISC recently sponsored a study at the University of Washington to investigate weaker beams in these frames, both to evaluate existing structures and to develop more efficient beam designs. This session discusses the seismic behavior of these systems, recent research, and a seismic retrofit design example of a braced-frame system.
