Abstract:A computational study was conducted to examine the seismic performance of steel moment‐resisting frames (MRFs) provided with chevron concentric braces. Such steel systems are widely used for buildings in Japan. Nonlinear finite‐element‐method models were validated against data and observations from previously tested chevron‐braced MRF specimens. The validated models were used to conduct a parametric study to understand how the cyclic‐loading performance of chevron‐braced MRFs may be affected by the torsional a… Show more
