Self-resetting steel beam column joint with composite energy dissipation mechanism
The invention provides a self-resetting steel beam column joint with a composite energy dissipation mechanism. The self-resetting steel beam column joint comprises two outer restraining plates and an inner rotating plate. The inner end of the inner rotating plate is clamped by the inner ends of the two outer restraining plates, and the inner rotating plate and the outer restraining plates are rotationally connected through a pin shaft; a plurality of energy dissipation steel bars penetrating through the outer restraining plate and the inner rotating plate are arranged around the center of the pin shaft, the outer end of the inner rotating plate is fixedly connected with the steel beam, and the outer end of the outer restraining plate is fixedly connected with the steel column. One end of a prestressed steel strand penetrates through the steel column and is fixedly connected with the steel column through a locking bolt, and the other end of the prestressed steel strand penetrates through the outer end of the inner rotating plate and an end plate of the steel beam and is fixedly connected with the steel beam through a locking bolt; the prestress steel strand provides reset force for the inner rotating plate and the outer restraining plate after rotating displacement occurs. The steel strand is adopted for resetting, the space requirement of the joint is not increased, and normal assembly of the wall and the floor slab can be ensured.
本发明提供一种具有复合耗能机制的自复位钢质梁柱节点，包括两个外约束板和一个内转动板；所述内转动板的内端被两个所述外约束板的内端夹持，并通过销轴转动连接；围绕所述销轴的中心设置有多个穿过外约束板和内转动板的耗能钢棒，所述内转动板的外端与钢梁固定连接，所述外约束板的外端与钢柱固定连接；预应力钢绞线的一端穿过钢柱并通过锁紧螺栓与所述钢柱固定连接，另一端穿过所述内转动板的外端和所述钢梁的端板，并通过锁紧螺栓与所述钢梁固定连接；所述预应力钢绞线为所述内转动板和所述外约束板发生转动位移后提供复位力。本发明采用钢绞线进行复位，未增加节点在空间上的需求，能够确保墙体、楼板的正常装配。
