摘　　要：在试验研究的基础上,分析双层钢板-内填混凝土组合剪力墙结构的受力特点,建立了带初始缺陷的有限元数值计算模型,并与试验结果进行了对比;通过有限元数值模拟,分析了轴压比、高宽比、宽厚比等主要参数对剪力墙滞回性能的影响规律及其特征.研究结果表明,高宽比、宽厚比、轴压比对双层钢板-内填混凝土组合剪力墙受力性能均有影响,轴压比是影响承载能力的主要因素,而高宽比与宽厚比是影响初始刚度的主要因素.This paper summarized the current research status of double-steel-layer-concrete composite shear wails. Then, it presented a brief introduction to the experiments of double-steel-layer-concrete composite shear wall. Based on the experimental study of double-steel-layer-concrete composite shear wall, the hysteretic behavior of the wall was analyzed and the finite element model with initial imperfections was es- tablished. Compared with the experimental results, the FEM model was verified to be efficient. Through numerical analysis, the influence of several parameters, including the high aspect ratio, the width-to-thick- ness ratio and the axial compression ratio, on the hysteretic behavior of the wall was explored. The numer- ical results have shown that all the 3 parameters have effects on the mechanical performance of the wall, the axial compression ratio is the most important factor for the loading capacity of the wall and the high aspect ratio and width-to-thickness ratio are the most important factors for the initial stiffness of the wall.
