对3个三层1/4缩尺比的高强钢筋高强混凝土双肢剪力墙进行了低周往复试验,并采用ABAQUS软件对其进行了非线性有限元弹塑性分析,得到了双连梁在弹塑性阶段的内力以及其变化规律。结果表明,有限元分析结果与试验结果吻合良好,表明高强钢筋高强混凝土双肢剪力墙具有一定的抗震性能;增加连梁跨高比可以避免连梁发生剪切破坏,进而增加连梁的延性;与单连梁相比,双连梁具有更好的延性和耗能能力。
Low-cycle reciprocating tests were carried out on three three-layer high-strength concrete high-strength concrete double-limb shear walls with 1/4 scale ratio. The nonlinear finite element elasto-plastic analysis was carried out by using ABAQUS software. Elasto-plastic stage of the internal forces and its variation. The results show that the results of finite element analysis are in good agreement with the experimental results, indicating that the high strength RC high-strength concrete double-wall shear wall has certain seismic performance. Increasing the span-height ratio of the connecting beam can avoid the shear failure of the connecting beam and increase the ductility ; Compared with a single beam, double beam has better ductility and energy consumption.
