AISC Research: Understanding and Improving the Seismic Performance of Chevron Configured Special Concentrically Braced Frames [U5]

Seismic lateral-force-resisting systems have used concentrically braced frames (CBFs) for many years. Chevron-braced (or inverted V-braced) frames are seldom used today because the current beam strength requirements result in very heavy beams. We'll summarize recent experimental and analytical research on beam yielding in chevron braced frames and provides design recommendations and examples.
