摘　　要：利用ANSYS有限元分析软件对受多个集中荷载作用的薄腹板梁的腹板横向加劲肋进行了弹塑性计算,分析了利用腹板屈曲后强度时,横向加劲肋的受力状态、破坏机理,并提出了横向加劲肋的强度计算公式及其设计方法。In this paper we study nonlinear ability of the transverse stiffeners of the thinned-web beam bearing several concentrated longitudinal strain actions with ANSYS finite element system methodThinking of using post-buckling strength of web plate,we study some facts about transverse stiffeners including strain ability,failure mechanismAt last we make out the formula of strength calculation of the stiffener bearing-load and the design method of the transverse stiffeners

关 键 词：薄腹板梁 屈曲后强度 横向加劲肋 有限单元法
