摘要：

In　this　paper,　nonlinear　finite　element　analysis　of　the　concrete　filled　steel　tubular　(CFST)　frame　with　dampers　is　performed　using　the　ABAQUS　software,　and　the　validity　and　feasibility　of　the　numerical　models　have　been　verified　by　the　comparison　between　experimental　results　and　calculation　results.　The　mechanical　performances　of　the　CFST　frame　with　BRB　and　CFST　frame　have　been　comparatively　analyzed　according　to　the　results　of　numerical　analysis,　and　the　force　analysis　of　whole　process　for　CFST　frame　with　dampers　has　been　done.　Mechanical　properties　of　the　CFST　frame　with　dampers　have　been　studied　in　the　aspects,　such　as　stress　state　of　external　steel　tube,　core　concrete　and　energy　dissipation　devices.　The　result　shows　that:　the　mechanical　properties　of　the　CFST　frame　have　been　enhanced　by　setting　the　BRB　in　the　structure,　whilst　the　development　process　of　plastic　hinge　has　been　delayed,　and　the　seismic　performance　of　the　CFST　frame　has　been　improved　effectively.
