摘　　要：以某大跨度双塔钢斜拉桥工程为背景,结合有限元法,对钢箱梁有效分布宽度(或应力不均匀系数)进行计算分析。结果显示,其顶、底板应力不均匀现象明显,设计中应加以考虑。Taking a steel long-span double-pylon cable-stayed bridge project as the background,the article calculates and analyzes the efficient distribution width(or stress non-uniform coefficient) of steel box girders by the finite element method.The result shows the stresses of its top and bed slabs are obviously uneven,which should be considered in the design.

关 键 词：钢桥面板 钢结构 有效计算宽度 有限元
