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。
Built-in steel reinforced concrete composite shear wall has good seismic performance, has been in the ultra-tall buildings more and more applications. The OpenSees program was used to simulate the experimental components of common RC shear wall and steel plate combined shear wall, which verified the rationality and accuracy of the modeling and analysis methods. The analysis results show that this method can well simulate the combined shear Elastic plastic behavior of the wall. The effects of the two key parameters of axial compression ratio and steel rationing on the seismic performance of the combined shear wall with built-in steel plates are analyzed. The calculated results show that the built-in steel plate can obviously improve the bearing capacity, ductility and hysteretic energy consumption of the RC shear wall compared with the ordinary RC shear wall. The axial compression ratio and steel ration have a great influence on the seismic performance of the RC shear wall .
