摘　　要：利用有限元程序ANSYS计算了192组有横向加劲肋的薄腹板简支梁。通过对计算结果的分析验证了《钢结构规范》(GB50017-2003)中对薄腹板梁腹板横向加劲肋设计规定的正确性,并补充了部分设计建议,完善了利用腹板屈曲后强度的工形简支梁腹板横向加劲肋的设计方法,供设计人员参考。In this paper 192 groups of girder model with the transverse stiffener were calculated with ANSYS finite element system software. It proves that the designing rules about the transverse stiffener in the Code for design of steel structures （GB50017-2003） are proper. And we also make some improvements on the design of the transverse stiffener in the use of the strength after bending of the transverse stiffener. The conclusions can provide useful reference for structure engineers.
