To　solve　the　issues　of　insufficient　bearing　and　energy　dissipation　capacities　of　rocking　bents,　a　double-column　rocking　bent　structure　with　braces　placed　in　chevron　arrangement　is　developed　in　this　study.　The　braces　are　pure　energy　dissipation　ones　or　self-centering　energy　dissipation　ones,　installed　between　the　cap　beam　and　the　foundation　of　the　double-column　rocking　bent　by　connecting　devices.　To　study　the　seismic　performance　of　the　double-column　rocking　bent　structure　with　braces　developed,　its　quasi-static　analysis　is　carried　out　firstly.　Taking　the　double-column　cast-in-situ　bent　and　the　double-column　rocking　bent　as　the　comparative　model,　the　hysteretic　behavior　of　the　double-column　rocking　bent　with　additional　braces　are　investigated;　The　dynamic　time　history　analysis　of　these　bents　is　carried　out　to　explore　the　dynamic　responses　of　the　structures　due　to　the　near-field　symmetrical　pulse,　to　near-field　asymmetrical　pulse　and　to　far-field　non　pulse　ground　motions.　These　results　show　that:　the　double-column　rocking　bent　with　additional　braces　still　behaviors　the　rocking　mechanism,　which　can　effectively　avoid　the　serious　damage　to　the　plastic　hinge　of　column;　at　the　same　time,　the　additional　braces　can　significantly　improve　the　bearing　capacity　and　energy　dissipation　capacity　of　the　bent　and,　reduce　the　displacement　response　of　the　bent;　especially,　the　self-centering　energy　dissipation　braces　can　also　provide　additional　self-centering　force　for　the　bent,　which　can　effectively　improve　the　seismic　performance　of　the　bent.　©　2024　Tsinghua　University.　All　rights　reserved.
