剪力墙系统常用于高层建筑结构中抵抗侧向荷载。复合钢板剪力墙(CSPSW)系统具有承载力高、延展性好、耗能能力强等特点,越来越多的用于钢结构中以抵抗侧向荷载。介绍了钢板剪力墙(SPSW)和复合钢板剪力墙(CSPSW)的相关试验。对两个1/3缩尺抛光试样进行焊接和测试,试验剪力墙系统由混凝土填充圆形中空截面(CHS)钢管柱、钢梁和SPSW或CSPSW组成。对试验结果进行分析和总结,结果显示SPSW和CSPSW系统具有良好的延展性和耗能能力。SPSW系统主要用于抵抗侧向荷载作用下薄壁钢板屈曲产生的薄膜张力引起的层间剪力。CSPSW系统中附加在钢板两侧的混凝土加固(RC)镶嵌板主要用于确保复合材料的性能,防止钢板屈曲。与SPSW系统相比,CSPSW系统的承载力和耗能能力显著增强。
Shear wall systems are commonly used in high-rise buildings to resist lateral loads. The composite steel plate shear wall (CSPSW) system has the features of high bearing capacity, good ductility and strong energy dissipation capability, and more and more used in steel structures to resist lateral loads. The related experiments of steel plate shear wall (SPSW) and composite steel plate shear wall (CSPSW) are introduced. Two 1/3 scale polished specimens were welded and tested. The test shear wall system consisted of concrete filled circular hollow section (CHS) steel columns, steel beams and SPSW or CSPSW. The test results were analyzed and summarized, the results show SPSW and CSPSW system has good ductility and energy consumption. The SPSW system is mainly used to resist the interlayer shear force caused by the film tension caused by the buckling of the thin-walled steel plate under lateral load. Concrete reinforcement (RC) panels attached to both sides of the steel sheet in the CSPSW system are primarily used to ensure the composite’s properties and prevent buckling of the steel sheet. Compared with the SPSW system, CSPSW system significantly enhance the carrying capacity and energy consumption.
