Self-resetting concrete column base joint with replaceable energy consumption assembly
The invention relates to a self-resetting concrete column base joint containing a replaceable energy dissipation assembly. The self-resetting concrete column base joint comprises a vertically-arranged prefabricated reinforced concrete column assembly, the replaceable energy dissipation assembly and a foundation assembly. The top face of the foundation assembly is connected with the prefabricated reinforced concrete column assembly through SMA ribs. The periphery of the bottom of the prefabricated reinforced concrete column assembly is connected with a replaceable energy dissipation assembly through energy dissipation connecting steel bars. One end of the SMA rib is pre-embedded in the foundation assembly, and the other end of the SMA rib penetrates through the prefabricated reinforced concrete column assembly and is anchored; the tail ends of the energy consumption connecting steel bars stretch out of the prefabricated reinforced concrete column assemblies and are fixedly provided with replaceable energy consumption assemblies. The replaceable energy dissipation assembly comprises two symmetrically-arranged friction energy dissipation assemblies and two symmetrically-arranged yield energy dissipation assemblies, each yield energy dissipation assembly comprises an energy dissipation swing plate perpendicular to the mounting face of the yield energy dissipation assembly, and the energy dissipation swing plates are connected with the top face of the foundation assembly. The device has the advantages of being good in anti-seismic performance, energy-saving, environment-friendly, convenient to construct, replaceable, self-resetting and the like.
本发明涉及一种含有可更换耗能组件的自复位混凝土柱脚节点，包括竖直设置的预制钢筋混凝土柱组件、可更换耗能组件及基础组件；所述基础组件的顶面通过SMA筋连接预制钢筋混凝土柱组件；所述预制钢筋混凝土柱组件底部四周通过耗能连接钢筋连接可更换耗能组件；所述SMA筋一端预埋在所述基础组件内，另一端穿过预制钢筋混凝土柱组件并锚固；所述耗能连接钢筋末端伸出预制钢筋混凝土柱组件并固装可更换耗能组件；所述可更换耗能组件包括两个对称设置的摩擦耗能组件和两个对称设置的屈服耗能组件，屈服耗能组件包括垂直于其安装面的耗能摆动板，耗能摆动板与基础组件的顶面连接。本发明具有抗震性能好、节能环保、施工便捷、可更换自复位等优点。
