Energy Dissipation Behavior and Simplification Analysis of Eccentrically Braced Frames Guan Kejian Wang Xinwu Peng Shaomin Ph. D.,School of Civil Engineering & Architecture, WUT, Wuhan 430070,China.Eccentrically braced frame is one of perfect lateral resistant systems. In the paper, the features and varieties of eccentrically braced frames are concluded. A kind of simplified calculation method is put forward, which could be used at the preliminary design stage.steel structure; energy dissipation behavior; eccentrically braced frame system
