为研究带约束拉杆钢板-混凝土组合剪力墙的抗震性能,制作10个钢板之间采用八螺母螺栓连接的钢板-混凝土组合剪力墙试件并对其进行拟静力试验,研究试件的破坏模式、变形能力及耗能能力,得到试件的滞回曲线、承载力、骨架曲线、刚度退化曲线、位移延性系数以及累计耗能曲线等,分析高宽比、约束拉杆间距、钢板厚度、核心混凝土厚度、轴压比及边缘增设型钢对试件抗震性能的影响。结果表明:钢板之间采用八螺母螺栓连接可行,带约束拉杆钢板-混凝土组合剪力墙抗震性能较好,随高宽比降低、约束拉杆间距减小、钢板厚度增大、核心混凝土增厚及边缘增设型钢,其抗震性能增强;端部增设型钢可显著提高试件承载力;减小约束拉杆间距可显著提高试件的延性。
In order to study the seismic performance of the steel-concrete composite shear wall with restrained tie bar, a steel-concrete composite shear wall specimen with eight nuts bolted between 10 steel plates was fabricated and subjected to quasi-static tests. The deformation, the energy dissipation capacity, the hysteresis curve, the bearing capacity, the skeleton curve, the stiffness degradation curve, the displacement ductility coefficient and the cumulative energy dissipation curve of the specimen were obtained. The aspect ratio, the restraining rod spacing, the thickness of the steel plate, Influence of core concrete thickness, axial compression ratio and edge profiled steel on the seismic behavior of specimens. The results show that it is feasible to use eight-nut bolt connection between the steel plates. The shear wall with restrained tie bar-concrete composite shear wall is better. As the aspect ratio decreases, the spacing of restraining tie bar decreases, the thickness of the steel plate increases, The addition of section steel to the edge enhances the seismic performance of the specimen. The additional section steel at the end can significantly increase the bearing capacity of the specimen, and the reduction of the restraining rod spacing can significantly improve the ductility of the specimen.
