摘要
针对4种新型框架连接形式(即钢筋搭接连接、预埋角钢连接、插筋连接和体外钢板连接)进行缩尺模型试验,研究了这4种类型连接的受弯承载力、塑性发展能力、抵抗变形能力及耗能能力.根据屈服弯矩、极限弯矩以及截面弯矩-转角曲线等试验值,对各种类型连接的综合性能进行评价.
In this paper,four new forms of connections,which are connection by lapping of bar,connection by embedded angle steel,connection by inserted reinforcement and connection by external steel plate,in framework are studied by scale model tests. According to the experimental values of yield moment,ultimate moment and the curve of bending moment-rotation,we analyzed the bending capacity,plasticity development capacity,deformation resistance and energy dissipation capacity of these four types of connections.
