Anti-buckling beam-column joint structure easy to replace
The buckling-restrained beam-column joint structure easy to replace comprises a cantilever beam section, a middle beam section, a web connecting piece and an energy dissipation assembly, and the web connecting piece and the energy dissipation assembly are both arranged between the cantilever beam section and the middle beam section; the top of the energy dissipation assembly is lower than the tops of beam wing plates of the cantilever beam section and the middle beam section and used for avoiding an upper floor slab. A through hole is formed in the center of the energy dissipation assembly. The web connecting piece penetrates through the through hole to connect the cantilever beam section and the middle beam section. The energy dissipation assembly and the web connecting piece are attached to beam webs of the cantilever beam section and the middle beam section, and the energy dissipation assembly bears plastic deformation and damage of the structure through out-of-plane buckling deformation of the energy dissipation assembly. The energy dissipation assembly is lower than the main body component, so that the energy dissipation assembly does not make direct contact with the upper floor slab, the performance of the energy dissipation assembly is prevented from being affected by the load of the upper floor slab, disassembly is easy after an earthquake, meanwhile, the web connecting piece is used for restraining out-of-plane yield of the energy dissipation assembly, and the energy dissipation performance of the energy dissipation assembly is improved.
本发明公开了一种易更换的防屈曲梁柱节点结构，包括：悬臂梁段、中间梁段、腹板连接件和耗能组件，腹板连接件和耗能组件均设置在悬臂梁段和中间梁段之间；耗能组件的顶部的高度低于悬臂梁段和中间梁段的梁翼板顶部的高度，用于避让上层楼板；耗能组件的中心具备通孔，腹板连接件穿过通孔连接悬臂梁段和中间梁段；耗能组件和腹板连接件均贴合悬臂梁段、中间梁段的梁腹板，耗能组件通过自身的面外屈曲变形承担结构的塑性变形和损伤。耗能组件低于主体构件，使耗能组件不直接接触上层楼板，从而避免自身的性能受到上层楼板的负载的影响，并且易于在地震之后拆卸，同时使用腹板连接件约束耗能组件的面外屈服，提高耗能组件的耗能性能。
