摘要

为解决薄钢板剪力墙受力上的缺陷，提出一种预应力索网抑制屈曲薄钢板剪力墙(CN-SPSW)，它的工作原理为在钢板两侧交错布置预应力拉索，由拉索内预应力产生的回复力约束钢板面外变形.利用ABAQUS对单层单跨预应力索网抑制屈曲钢板剪力墙的抗剪性能进行数值模拟，分析在水平方向低周往复加载作用下，构件的抗剪性能及耗能能力.研究表明：索网为柔性约束，抑制较厚钢板的面外变形效果较弱，但对于大宽厚比的钢板剪力墙，预应力索网抑制构件的存在仍可显著减少钢板面外变形.针对宽厚比λ=1 000的CN-SPSW，相较于同尺寸的钢板剪力墙，其峰值承载力提高18%，耗能能力提高47%.参数分析表明索网抑制构件宜用于宽厚比λ大于600的钢板剪力墙中.

Abstract

To optimize the mechanical performance of steel plate shear wall (SPSW)

a novel buckling restrained steel plate shear wall (CN-SPSW) was proposed. In the CN-SPSW

prestressted cable nets were placed on the either side of infill panels to restraint the early buckling

and the out-of-plane deformation would be restricted by the panel's pre-tension. A non-linear finite element model was established via ABAQUS software package to study the hysteretic behavior of CN-SPSWs. The results show that the cable net is a kind of flexible buckling-restrained member

and it can reduce the out-of-plane deformation of infill panels significantly. Compared with the steel plane shear wall

peak bearing capacity and energy dissipation capacity of CN-SPSW are increased by 18% and 47% respectively with a width-to-thickness ratio of 1 000. Parameter analyses suggest that prestressted cable nets should be applied to SPSW whose width-to-thickness ratio is more than 600.
