| 摘 要： | 根据对低周反复荷载作用下11根L形截面宽肢框架柱的剪切破坏试验,对L形宽肢柱受剪破坏机理以及水平加载角度、暗柱、截面肢高厚比对L形宽肢柱受剪性能的影响进行研究。试验表明,L形截面宽肢柱斜面受剪承载力高于主轴向;配筋合理的暗柱对L形宽肢柱受剪承载力及延性有提高作用;随截面肢高厚比的增加,试件受剪破坏过程的脆性增加。

| Abstract: | On the basis of the experiment on shear failure of 11 L-shaped section broad-limb frame columns subjected to low cyclic loading,the influence of horizontal looading angle,embedded column and ratio of section width to height on its shear behavior has been analyzed as well a selements'shear failure mechanism.From the results it is indicated that L-shaped section broad-limb-columns have higher shear strength with oblique loads.The embedded column with proper bar would reinforce members'shear strength and ductility.The members'brittleness will rise with ratio of its section height to width increasing inthe process of shear failure. |

| Keywords: | L-shaped section broad-limb column angle of loading embedded column ratio of section height to width shear behavior |
