| 摘 要： | 以跨高比为参数,进行两组(两种典型截面)8片冷弯薄壁型简支钢梁在循环荷载作用下的试验.研究了试件的破坏形态,对其弯矩-曲率滞回曲线、骨架曲线进行分析,考察其滞回性能、延性、耗能能力等重要抗震性能指标.结果表明:冷弯薄壁型钢梁的荷载-位移滞回曲线比较饱满,没有明显的捏缩现象,具有很好的延性和耗能能力;跨高比和宽厚比会严重影响冷弯薄壁型钢梁的滞回性能和延性.

| Abstract: | Eight thin-walled cold-formed steel beams were in cyclically increased loading conditions during the experiment.It investigated the failure shape,and analysed moment versus curvature hysteretic curves.By the analyses,some important parameters of earthquake resistant capability can be reviewed,such as hysteretic behavior,ductility and energy dissipation.They are listed as follows:The Cold-formed thin-walled steel beams exhibits stable hysteresis behavior up to local buckling,and then shows considerable good ... |
