| 摘 要： | 内置钢板钢筋混凝土组合剪力墙具有良好的抗震性能,目前已在超高层建筑中得到越来越多的应用。采用OpenSees程序对普通钢筋混凝土剪力墙和钢板组合剪力墙试验构件进行模拟分析,验证了建模与分析方法的合理性与准确性,分析结果表明,该方法能够较好地模拟组合剪力墙的弹塑性行为。分析了轴压比和配钢率这两个关键参数对内置钢板组合剪力墙抗震性能的影响。计算结果表明,与普通钢筋混凝土剪力墙相比,内置钢板可以明显提高构件的承载力、延性和滞回耗能;轴压比和配钢率对组合剪力墙的抗震性能有较大影响。

| Abstract: | To improve the seismic performance of shear walls located in the bottom zone of super high-rise buildings,the steel plate-reinforced concrete composite shear wall（SPRCW）has been used in engineering practice increasingly.Comparison of test results based on the traditional reinforced concrete shear wall and SPRCW indicates that the analytical model is reasonable and the inelastic behavior of the SPRCW can be predicted well by the numerical analysis based on OpenSees.The primary parameters include axial load ratio and the ratio of steel plate.Numerical analytical results indicate that compared with the conventional RC shear walls,the lateral load carrying capacity,ductility and energy dissipation capacity of SPRCW are improved significantly.In addition,the axial load ratio and the ratio of steel plate have significant effects on seismic performance of SPRCW. |
