| Abstract: | 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. |
