中文摘要：

改进型组合钢板剪力墙（I-CSPW）和防屈曲钢板剪力墙（BR-CSPW）均由边缘框架、钢板和与钢板用螺栓连接的混凝土板构成,但BR-CSPW在混凝土板上预留了比螺杆直径大的孔。进行了两种组合钢板剪力墙的低周反复加载试验,研究了I-CSPW和BR-CSPW在水平往复荷载作用下的破坏模式、承载力、抗侧刚度、耗能能力和延性。利用ABAQUS软件建立有限元模型,通过变化钢板和混凝土板的厚度,考察两种组合剪力墙在水平荷载作用下的承载力、抗侧刚度及混凝土损伤的差异。结果表明,随着钢板厚度增大,I-CSPW的混凝土板损伤发生时间提早,损伤程度增大。相反,钢板厚度的增大却能延迟BR-CSPW的混凝土板破坏。为抑制钢板屈曲,BR-CSPW所需的混凝土板厚度较I-CSPW小。

英文摘要：

Two composite shear wall systems studied herein consist of steel boundary frame and steel plate with reinforced concrete plates attached to both sides by bolts. In the system called ＂innovative＂ composite shear wall （I-CSPW） the bolt hole in the concrete plate is in direct match with the bolt rod, while in the system called buckling-restrained steel plate shear wall （BR-CSPW） there is a gap in between. This paper presents the results of model tests and behavior aspects of the two composite shear walls under cyclic loading including the failure modes, strength, stiffness, energy dissipation capacity and ductility. Analytical models for the shear strength, stiffness and concrete damage of the composite wails are developed by using ABAQUS software. Results indicate that with increase in steel plate thickness the concrete plate damage decreases in BR-CSPW, while in I-CSPW, concrete plate damage occurs earlier and more seriously. Hence to restrain buckling of steel plate, thicker concrete plate should be used in I-CSPW than in BR- CSPW.
