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。将钢骨设计在各构件和梁柱结构的中心区域,钢骨的连接过程不连续,主要连接材料为钢筋混凝土。本文以综合试验法,选取4个比例为1/2的装配式混凝土梁柱节点结构,开展节点低周往复荷载试验,并选择2个相同使用工况的梁柱中节点展开对比研究,总结分析了6个试件结构的破坏规律、滞回曲线及承载力变化等,得出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 the assembled concrete structure,the connection method of the nodes in the beam and column is very important,and it is also the difficulty of the design of the current assembled building structure.The steel skel⁃eton is designed in the central area of each member and the beam-column structure.The connection process of the steel skeleton is discontinuous,and the main connection material is reinforced concrete.In this paper,a compre⁃hensive test method is used to select 4 prefabricated concrete beam-column joint structures with a ratio of 1/2,to carry out the low-cycle reciprocating load test of the joints,and to select two beam-column joints under the same working conditions to conduct a comparative study.The failure rule,hysteresis curve and bearing capacity of 6 specimen structures are summarized and analyzed.It is concluded that the stability,design reliability and seismic performance of the joints in the assembled concrete beam and column are good.
