在试验研究的基础上，用非线性有限元分析软件 MSC.Marc 对高阻尼混凝土带钢板暗支撑双肢剪力墙进行了低周反复荷载下的数值模拟，并分析了轴压比、配钢率、高宽比和连梁刚度等对高阻尼混凝土带钢板暗支撑双肢剪力墙承载力和变形性能的影响规律.分析结果表明，数值模拟结果和试验结果吻合较好，当轴压比大于0.4时，高阻尼混凝土钢板暗支撑双肢剪力墙的延性显著下降，相对暗支撑配钢率为0.96~6.73时，能较好地改善双肢剪力墙的极限承载力.连梁跨高比、高宽比主要影响双肢剪力墙的承载力和变形性能.研究结果对高阻尼混凝土暗支撑双肢剪力墙的地震弹塑性计算具有一定的参考价值.

Based on the existing experimental data,a finite model of HDCSW with steel plate concealed bracing under low-cycle load was established reasonably with nonlinear finite element analysis software MSC.Marc.The influence of axial compression,steel ratio,height-width ratio and span-depth ratio on the capacity and deformation performance of HDCSW with steel plate concealed bracing was analyzed systemi-cally.If the axial compression ratio is greater than 0.4,the ductility of HDCSW with steel plate concealed bracing will be obviously decreased.When the relative ratio of the steel plate concealed bracing is between 0.96 and 6.73,it will improve the ultimate bearing capacity of HDCSW with steel plate concealed bracing. The height-width ratio and span-depth ratio have a major effect on the capacity and deformation perform-ance.The research results of HDCSW with steel plate concealed bracings have a certain reference value with elastic-plastic calculation under seismic.
