内置型钢的装配式RC梁柱节点抗震性能研究
Research on seismic performance of prefabricated RC beam-column joints with embedded steel sections
摘要
Abstract
The connection form of beam-column joints is a key factor influencing the seismic performance of prefabricated building structures.To simultaneously meet seismic performance requirements and enable efficient construction,this paper proposes a novel connection form for prefabricated reinforced concrete beam-column joints with embedded steel sections.A full-scale precast edge-joint specimen and a corresponding cast-in-place edge-joint specimen were fabricated and tested as a control group under pseudo-static loading.The research results show that:the joint exhibited a beam-end plastic hinge failure mode;the load-displacement curve demonstrated favorable fullness,reflecting good ductility and energy dissipation capacity;shear failure was effectively prevented in the joint core region,achieving the"strong joint,weak component"seismic design objective.关键词
