| 摘 要： | 运用有限元ANSYS程序,重点分析了在均布荷载下,横向加劲肋对钢梁的整体稳定承载力的影响。通过对横向加劲肋不同布置情况的钢梁构件的计算,将得到的钢梁整体稳定临界承载力数值与同条件下没设加劲肋时的钢梁承载力进行对比,得出了加劲肋与钢梁整体稳定承载力提高系数η的规律,提出了考虑横向加劲肋影响时简支钢梁在均布荷载作用下整体稳定性计算公式。

| Abstract: | In this paper, the Finite Element Method is applied to analyse the effect of horizontal stiffening rib on stabih'ty of steel beam under the uniformly distributed loads. Considering different shapes of horizontal stiffening ribs, the paper gets the beam's stable carrying capacity. By comparing the results with those without horizontal stiffening ribs, the enhancing coefficient 77 is presented in this article to measure the horizontal stiffening rib's contribution to the overall stabih'ty of the beam,and the corresponding estimate formula of stable capacity with the horizontal rid is given. |
