This　paper　presents　the　seismic　behavior　of　a　precast　concrete　frame　with　buckling-restrained　braces　(BRBs-PC　frame)　and　analyzes　the　structural　failure　mode　caused　by　the　horizontal　force　of　BRBs.　Two　half-scale　PC　frames,　with　and　without　BRBs,　were　designed　and　tested　using　a　pseudo-static　test.　During　the　test,　the　BRBs-PC　frame　exhibited　a　failure　mode　of　beam-hinge　with　BRBs.　When　the　BRBs-PC　frame　yielded,　the　ratio　of　the　BRB’s　energy　dissipation　to　total　energy　dissipation　was　65%.　Cracks　appeared　on　the　column’s　superimposed　surfaces.　The　ultimate　bearing　capacity　and　energy　dissipation　of　the　BRBs-PC　frame　were　significantly　improved.　©　2022　Taylor　&　Francis　Group,　LLC.
