| 摘 要： | 在纯弯或纯剪分别作用下的工字形焊接板梁,在弹性范围内腹板屈曲时,翼缘会对腹板起约束作用。通过采用柱稳定特微函数的形函数,用伽勒金法计算表明,其翼缘约束作用的大小,是与翼缘和腹板的尺寸有关。

| Abstract: | When a welded I-section plate girder is subjected to bending or shearing,buckling of web in elastic range will be restrained by flanges.Analysis madewith Gatekin's method using characteristic function of buckling of strut as a form function,has shown that the restrint of the flange depends upon the size of the flange and the web. |

| Keywords: | Restraint of flange Buckling of web Factor of stability |
