Energy-Based Seismic Design of Buckling-Restrained Braces

摘要

Energy-based seismic design procedure for framed structures with buckling-restrained braces is proposed.The cross-sectional area of braces required to meet a given target displacement is obtained by equating thehysteretic energy demand to the accumulated plastic energy dissipated by braces. The design procedurewas applied to 3- and 8-story framed structures with buckling-restrained braces. According to analysisresults, the mean values for the top story displacement correspond well with the given performance targetdisplacements.
