【摘要】：设计制作了2片2层单跨缩尺比为1∶3的装配式钢管混凝土组合剪力墙,主要考虑墙体设置竖向拼缝对其抗震性能的影响,通过对试件进行低周反复荷载试验,分析了结构的破坏形态、变形性能、滞回曲线、刚度退化及耗能能力。结果表明:装配式钢管混凝土组合剪力墙的主要破坏形态为弯剪破坏,可以分为弹性、弹塑性和软化三阶段;墙体竖向拼缝处是由水平封闭U形筋与矩形箍筋环内插入纵筋进行连接,试验测得拼缝处的滑动位移均小于0.02mm,基本没有错动,说明该构造措施可行;竖向拼缝的存在对组合剪力墙整体受力性能、承载力以及耗能、延性、刚度等抗震性能没有明显影响,其构造措施满足墙体受力要求。
[Abstract]:Designed and produced 2 pieces of 2 layer single span scale is 1: 3 assembled steel pipe concrete composite shear wall, mainly considering the influence of the vertical seam wall set on its seismic performance, through the cyclic loading test of specimen, analysis of failure form, structure deformation, hysteretic curve, stiffness degradation and energy dissipation capacity. The results showed that the main failure form of assembled steel pipe concrete composite shear wall for flexural shear failure, can be divided into elastic, elastic-plastic and softening stage three; wall vertical seams is closed by the level of U shaped reinforcement and rectangular stirrups are connected into longitudinal reinforcement ring, sliding displacement test the seams are less than 0.02mm, basically no fault, indicating that the structure of feasible measures; the vertical seam of composite shear wall overall mechanical properties, bearing capacity, ductility, energy dissipation, stiffness and seismic performance of the structure has no obvious effect. The measures meet the force requirements of the wall.
