Self-resetting supporting assembly type friction connection joint and performance design method thereof
The invention relates to a self-resetting supporting assembly type friction connecting joint and a performance design method thereof. The connecting joint comprises a joint plate, a connecting lug plate, a connecting flange, a high-strength bolt and a friction plate. Through friction sliding connection, the limit axial force of the self-resetting support is irrelevant to the limit stroke, the situation that when structural deformation is large, the self-resetting support transmits a large load to a connecting joint and a main body structure is avoided, a beam column of the main body structure and a joint area of the beam column are protected, meanwhile, higher energy dissipation capacity is provided for the structure, and the energy dissipation effect is improved. The connecting joint is simpler in structure and high in assembly degree; the limit axial force of the self-resetting support and the pre-tightening force, the energy-dissipating capacity, the activating force, the limit stroke after activation and the bearing capacity of the connecting joint are easy to adjust; the invention further provides a performance-based design method comprehensively considering the whole-process cooperative work of the self-resetting support and the connection node, and the method can be directly used for engineering design.
本发明为一种自复位支撑装配式摩擦连接节点及其性能化设计方法，连接节点包括节点板、连接耳板、连接法兰、高强螺栓和摩擦片；本发明通过摩擦滑移连接，实现了自复位支撑的极限轴力与极限行程不相关，避免结构变形较大时自复位支撑传递较大荷载到连接节点和主体结构，对主体结构的梁柱及其节点域起到了保护作用，同时为结构提供更强的耗能能力，所述连接节点在构造上更加简单，装配化程度高；本发明实现了自复位支撑极限轴力和所述连接节点预紧力、耗能能力、激活力、激活后极限行程以及承载能力易于调整；本发明还提出了综合考虑自复位支撑和连接节点全过程协同工作的性能化设计方法，能够直接用于工程设计。
