摘要
分析了预制装配式框架结构在地震韧性方向的发展现状,探讨其在减震及可恢复功能结构方向的主要节点及连接形式的抗震研究进程,并提出一种新型可恢复功能全装配钢筋混凝土框架节点。新型节点主要由可更换损伤可控钢制铰和钢管约束核心区组成,可将节点的塑性铰外移至梁端的耗能铰上,引导结构形成合理失效模式,在“强节点弱构件”的抗震理念下,实现装配式框架结构的震损可修复功能。
The development status of prefabricated frame structures in the direction of seismic resilience were discussed,the seismic research progress of their main joints and connection forms in the direction of seismic decrease and recoverable function were discussed,and a new fully assembled reinforced concrete frame joints with structural reparability was proposed.The new joint is mainly composed of replaceable steel energy dissipation hinge and steel pipe constraint core area.The plastic hinge of the joint can be moved to the energy dissipation hinge of the beam end to guide the structure to form a reasonable failure mode.Under the seismic concept of "strong connect and weak member",the structural reparability after earthquake-induced damage of the prefabricated frame structure could be realized.
