中文摘要：

为了避免钢板混凝土组合剪力墙中钢板出现剪切屈曲,同时也能调整结构的刚度,通过在钢板上开竖缝,基于ANSYS有限元程序,分析钢板边长比、高厚比及侧向混凝土板厚度对未开缝钢板混凝土组合剪力墙的极限承载力和刚度的影响;研究钢板边长比、高厚比、侧向混凝土板厚度及缝间小柱高宽比对开缝钢板混凝土组合剪力墙抗剪承载能力和初始刚度的影响,比较开缝和不开缝钢板混凝土组合剪力墙的抗剪性能.结果表明：混凝土板作为侧向约束的存在显著地提高了钢板混凝土剪力墙的极限承载力;钢板开缝后其极限承载力虽有所降低,但通过改变开缝特征调节了其极限承载力和初始刚度;边长比、高厚比和钢板开缝显著地影响剪力墙的极限承载力.

英文摘要：

As a new type of shear wall,steel plate-concrete composite shear wall can avoid shear yielding and adjust stiffness of structure by opening vertical slits.This paper conducts a finite element simulation by ANSYS,and effects of span-to-height ratio,height-to-thickness ratio and the thickness of concrete panels on the ultimate capacity and stiffness of steel plate-concrete composite shear wall without slits are studied.Meanwhile,effects of span-to-height ratio,height-to-thickness ratio,the thickness of concrete panels and height-to-thickness ratio of columns between slits on shear walls with slits are analyzed,and the shear properties are compared between shear walls without slits and shear walls with slits.It is indicated that the ultimate capacity of steel plate-concrete composite shear walls is evidently improved by constraint effects of concrete panels;the ultimate capacity is reduced after opening slits,but the ultimate capacity and initial stiffness can be adjusted by changing characteristics of opening slits;the and ultimate capacity of shear walls is evidently affected by span-to-height ratio,height-to-thickness ratio and the thickness of concrete panels.
