摘 要: 按照钢板和混凝土板的位置关系将钢板-混凝土组合剪力墙分为3类:钢板-外包混凝土组合剪力墙(concrete-steel-concrete composite shear walls, CSC walls)、单侧钢板-混凝土组合剪力墙(concrete-steel composite shear walls, CS walls)和双层钢板-内填混凝土组合剪力墙(steel-concrete-steel composite shear walls SCS walls),结合国内外学者在此领域已做的研究,对其各自的受力特性进行评价。钢板-外包混凝土组合剪力墙和单侧钢板-混凝土组合剪力墙,仅利用混凝土板平面外刚度,未利用混凝土板平面内刚度和承载能力,反而增大了荷载。双层钢板-内填混凝土组合剪力墙,混凝土位于核心区,受到周围钢板约束处于三轴受压状态,同时也能防止钢板过早屈曲,钢板和混凝土的材料性能都得到较大提高。
关 键 词: 钢-混凝土组合结构;屈曲;三轴受压;平面外刚度;双层钢板-内填混凝土组合剪力墙

Abstract: This paper wrote three kinds of steel plate-concrete composite walls that were concrete-steel-concrete composite shear walls (CSC walls), concrete-steel composite shear walls (CS walls) and concrete-steel-concrete composite shear walls (SCS walls) which were classified according to the relative position of steel plate and concrete. On the basis of the present research finished in this field, a comparative analysis of their respective mechanical characteristics was made. Concrete-steel-concrete composite shear walls and concrete-steel composite shear walls make good use of the stiffness out of plane of the concrete plate avoiding buckling of steel plate, but fail to use the stiffness in plane and capability of the concrete plate resulting in load increasing. Concrete-steel-concrete composite shear walls can fully utilize the properties of these two materials because the concrete bond by the steel plate is in triaxial compression and can protect the steel plate from buckling too quickly.
Key words: steel-concrete composite structure; buckling; triaxial compression; the stiffness out of plane; concrete-steel-concrete composite shear walls
