【摘要】：通过两组钢板夹芯混凝土组合剪力墙的拟静力试验,对双向压弯荷载作用下钢板混凝土组合剪力墙的承载能力、变形能力和破坏模式进行研究,获得了试件的典型破坏形态、滞回曲线、骨架曲线、延性系数以及耗能能力等,分析面外弯矩的变化对结构力学性能的影响。研究表明:在双向压弯作用下,试件的破坏形态主要是压弯破坏;试件滞回曲线不够饱满,耗能能力一般;面外弯矩越大,试件的抗侧承载力及耗能性能越差;试件进入塑性阶段后,面外位移显著增加,呈发散趋势;试件底部截面基本满足平截面假定。
[Abstract]:Through the quasi-static test of two groups of steel plate sandwich concrete composite shear walls, the load-bearing capacity, deformation capacity and failure mode of steel plate concrete composite shear walls under biaxial compression and bending load are studied, and the typical failure modes of the specimens are obtained. The hysteretic curve, skeleton curve, ductility coefficient and energy dissipation capacity are analyzed. The results show that the failure mode of specimens under biaxial compression and bending is mainly compression and bending failure. The hysteretic curve of the specimen is not full enough and the energy dissipation ability is general; the larger the out-of-plane bending moment, the worse the lateral bearing capacity and energy dissipation performance of the specimen, and the more obvious the out-of-plane displacement increases after the specimen enters the plastic stage, the more divergent the out-of-plane displacement is. The bottom section of the specimen basically meets the assumption of flat section.
