This paper summarized the current research status of double-steel-layer-concrete composite shear walls.Then,it presented a brief introduction to the experiments of double-steel-layer-concrete com-posite 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 as-pect ratio and width-to-thickness ratio are the most important factors for the initial stiffness of the wall.
