摘　　要：结合钢箱梁设计工程实践,利用有限元程序ANSYS7.0对钢箱梁顶板、底板开口加劲肋进行了全面的计算分析,模型采用Shell63单元离散,通过计算给出了开口加劲肋的间距、高度对钢箱直梁桥和钢箱弯梁桥受力性能的影响规律,从而达到加劲肋优化设计的目的,为同类桥梁设计提供参考。On the basis of steel box girder design engineering practice, it is conducted a full calculation and a analysis of the stiffeners for steel box girder roof and floor using ANSYS 7.0. It is found that there is apparent regularity between the height and space of the stiffeners and the stressed performance of the straight steel box girder and the curved box girder bridge. Thus it offers an effective method for the optimum design of stiffener.
