［摘要］针对银川绿地中心型钢混凝土柱钢筋较多、部分钢筋穿透型钢，造成节点构造复杂、施工难度大等缺点，结合工程实际设计了两种不同于标准做法的构造措施，进行了缩尺构件的抗震性能试验，对比分析三种不同构造措施的型钢混凝土柱在低周往复荷载作用下的破坏形态、滞回曲线、骨架曲线、承载力、刚度退化、耗能能力等。结果表明，三种不同构造措施的型钢混凝土柱承载力相差不大，耗能性能相当。设计的两种代替构造措施可以应用于工程。

Abstract: In view of the fact that there are many steel bars in the steel reinforced concrete columns of Yinchuan Green Space Center and some steel bars penetrate the steel, which has the disadvantages of complicated joint structure and difficult construction. Combined with engineering practice, two  structural measures different from the standard were designed and the seismic performance test of the scale members was carried out. The failure modes, hysteresis curves, skeleton curves, bearing capacity，stiffness degradation and energy dissipation capacity of steel reinforced concrete columns with three different structural measures under low cycle reciprocating load were compared and analyzed. The results show that the bearing capacity of steel reinforced concrete columns with three different structural measures is not much different, and the energy dissipation performance is almost the same. Therefore, the two alternative construction measures designed  can be applied to engineering.
