【摘要】：为研究预制外墙挂板对钢筋混凝土剪力墙结构抗震性能的影响,进行了6个单层双肢剪力墙足尺试件的拟静力试验.通过对比试件的受力过程和破坏形态,研究预制外墙挂板-剪力墙结构的受力机理和抗震性能、外墙挂板对剪力墙抗侧刚度的影响以及轴压比的不同是否会影响外墙挂板对剪力墙抗侧刚度的贡献作用,验证外墙挂板与剪力墙之间连接构造的合理性.研究结果表明:带有预制外墙挂板的剪力墙试件的承载力和延性均高于纯剪力墙试件;在一定范围内,轴压比越大,外墙挂板对剪力墙抗侧刚度的影响越小;外墙挂板与剪力墙之间的平面外连接是否可靠,有待进一步分析研究.
[Abstract]:In order to study the effect of prefabricated external wall slabs on seismic behavior of reinforced concrete shear wall structures, quasi-static tests of six single-story two-leg shear wall full-scale specimens were carried out.The mechanical mechanism and seismic behavior of prefabricated external wall slab-shear wall structures are studied by comparing the stress process and failure patterns of the specimens.The influence of the external wall hanging board on the lateral stiffness of the shear wall and whether the difference of axial compression ratio will affect the contribution of the external wall hanging board to the lateral stiffness of the shear wall is verified to verify the rationality of the connection construction between the external wall hanging board and the shear wall.The results show that the bearing capacity and ductility of shear wall specimens with prefabricated external wall hangers are higher than those of pure shear wall specimens, and the greater the axial compression ratio is, the less the influence of external wall hanging panels on the lateral stiffness of shear walls is.Whether the outer-plane connection between the external wall and the shear wall is reliable or not needs further analysis and study.
