摘　　要：为研究铸钢节点连接装配式型钢混凝土复合墙的破坏机理和抗震性能,对1∶2缩尺的型钢混凝土复合墙试件进行了拟静力试验,通过改变墙体的内置型钢类型,对比分析其在低周往复荷载作用下的破坏过程、破坏模式、滞回特性、抗剪承载力、变形能力、墙体损伤以及耗能能力等,试验结果表明:焊接结构用铸钢节点强度和刚度大、安全性高,可以应用于型钢混凝土复合墙的现场装配式连接中;型钢混凝土复合墙均发生整体剪切破坏,其抗剪承载力、耗能和变形能力较钢筋混凝土复合墙均有较大程度的提高.结合工程实际,给出了型钢混凝土复合墙的现场装配方案.To study the failure mechanism and seismic performance of prefabricated steel reinforced concrete composite walls with steel castings,quasi-static tests were carried out on steel reinforced concrete composite walls with a scale of 1∶2.The steel reinforced concrete composite walls under low cycle reciprocating loads were contrastively analyzed on failure processes,failure modes,hysteretic characteristics,shear capacity,deformation capacity,wall damage and energy dissipation capacity by changing their built-in steel types.The experimental results showed that the steel castings used for welded structures have high strength,stiffness and safety,and can be applied to the on-site prefabricated connections of steel reinforced concrete composite walls.The overall shear failure occurred in steel reinforced concrete composite walls,and their shear capacity,energy dissipation and deformation capacities were greatly improved compared with those of reinforced concrete composite walls.In combination with engineering practice,an on-site assembly scheme for steel reinforced concrete composite walls was given.
