装配式建筑剪力墙结构抗震性能分析

Analysis of Seismic Performance of Prefabricated Shear Wall Structures

为深入分析装配式建筑剪力墙结构的抗震性能,文中对比分析3种剪力墙结构试件的荷载-位移曲线、刚度退化曲线、延度性能以及耗散性能。结果表明,随着加载位移的增加,装配式剪力墙承受的荷载水平表现为先近似线性增加,然后快速降低再缓慢降低的变化规律;装配式剪力墙的刚度退化曲线呈现出近似正态分布的的变化规律;柱截面结构尺寸越小,装配式剪力墙的延性性能越好,轴压比越大,装配式剪力墙的延性性能越好;柱截面尺寸越大,装配式墙体结构试件的屈服性能越强,轴压比越小,装配式墙体结构试件的屈服性能越强。

In order to deeply analyze the seismic performance of prefabricated shear wall structures,the load-displacement curves,stffness degradation curves,ductility properties and dissipation properties of three kinds of shear wall structures were compared in this paper.The results show that with the increase of loading displacement,the load level of the assembled shear wall increases approximately linearly at first,then decreases rapidly and then slowly.The stiffness degradation curve of the prefabricated shear wall shows an approximate normal distribution.The smaller the section size of the column,the greater the ductility and axial compression ratio,the greater the ductility of the prefabricated shear wall.The larger the column section size,the stronger the yield performance of the prefabricated wall structure specimen,the smaller the axial compression ratio,the stronger the yield performance of the prefabricated wall structure specimen.
