摘　　要：通过对装配整体式混凝土框架梁-柱边节点的低周反复荷载试验,研究其破坏形态和破坏机理,分析了构件受力的滞回曲线、骨架曲线、延性系数等抗震性能指标,并对节点安全性进行评判。试件满足"强柱弱梁"、"强剪弱弯"和"强节点、强锚固"的要求,具有良好的延性、整体性及耗能能力,抗震性能良好。试验为装配整体式钢筋混凝土框架结构体系的推广应用提供试验论证,促进装配整体式混凝土结构的发展。Through the low cyclic loading test on a beam-column exterior joint of assembled monolithic concrete frame structure,this paper studied on its failure mode and failure mechanism,analysed the aseismic behaviour indexes of hysteresis curve、skeleton curve、ductility factor ect,and gave evaluation on the safety of the joint.The specimen satisfied the requirements of ＂strong column weak beam＂、＂strong shear weak bending＂ 、＂strong joint 、strong anchoring＂,its ductility、integrity and energy dissipation capacity are well.These show that it has a good seismic behavior.This test could give a experiment proof on the popularization and application of assembled monolithic reinforced concrete frame structure system and will promote its development.
