摘　　要：针对装配式混凝土结构,梁柱中节点连接方式至关重要,也是当前装配式建筑结构设计的难点。文章以综合试验法,选取4个1/2比例装配式混凝土梁柱中节点,进行对比试验,开展低周往复荷载试验,重点研究和分析节点区域加劲腹板厚度和开孔影响,研究该节点的受力特性及抗震性能。总结分析了4个试件结构的破坏规律、滞回曲线及承载力变化等,发现装配式混凝土梁柱中节点的稳定性、设计可靠性及抗震性能较好。For prefabricated concrete structures,the connection mode of beam and column joints is very important,which is also a difficult point in the structural design of prefabricated buildings.In this paper,we use the comprehensive test method that choose four of half precast concrete beam and column joints were selected for comparison test,and low-cycle reciprocating load test was carried out to focus on the study and analysis of the influence of stiffening web thickness and hole opening in the joint area,so as to study the stress characteristics and seismic performance of the joints.The hysteretic curve and bearing capacity change of four specimens are summarized and analyzed.It is found that the stability,design reliability and seismic performance of the joints in the precast concrete beams and columns are better.
