摘要
在低屈服点钢板剪力墙体系中,内嵌钢板使用低屈服点钢,周边框架使用普通钢材。采用数值方法研究低屈服点钢板剪力墙在单调荷载作用下的抗剪性能和在反复周期荷载作用下的滞回性能。对内嵌钢板的屈服强度和高厚比进行参数分析,用于研究其对结构抗震性能的影响;分析显示低屈服点钢板剪力墙有很好的变形能力和耗能性能且能减小对主框架的影响。
In the LYP steel plate shear wall system, the low yield point (LYP) steel is selected for the infill panel while the boundary frame is constructed by conventional structural steel. The seismic resistant characteristics of low yield point (LYP) steel shear wails are examined in the reported research. The effects of height-to-thickness ratio and yield strength on the shear buckling of LYP steel plates are examined in this paper. Excellent deformation and energy dissipation capacity were obtained for the LYP steel shear walls.
