| 摘 要： | 在剪力作用下,当钢梁腹板高厚比较大时,腹板会沿主压力方向发生屈曲,从而降低钢梁承载力,为此提出了在腹板主压应力方向设置斜向加劲肋,以提高腹板的抗屈曲能力.对腹板设置斜向加劲肋的简支钢梁及在梁长四分点设置或不设置加劲肋的平腹板简支钢梁进行了跨中集中荷载作用下的静力试验,对其受力性能进行了分析,着重探讨了设置斜向加劲肋工字钢梁的腹板局部屈曲性能、屈曲形式、屈曲后强度和承载能力.试验研究表明,腹板设置斜向加劲肋工字钢梁具有优异的屈曲后能力,钢梁的极限承载能力大大提高. |
| 关 键 词： | 钢梁 试验 局部屈曲 斜向加劲肋 承载能力 |

| Abstract: | When the ratio of height to thick of girder web is relative large,the web will buckle along main pressure direction under shear force and the bearing capacity of the girder will be decreased consequently.The girder web with inclined stiffeners along the main pressure direction was put forward in order to advance buckling strength of the web.The experiment for the steel girder with inclined stiffeners and the normal plane web steel girder with or without stiffeners at quarter of length under concentrate load... |
| Keywords: | girder experiment local buckling inclined stiffeners bearing capacity |
