- Steel box continuous curved beam with its big span, little section, esthetical sculpt, is adopted generally by municipal projects.
- Applying the theory of curved beam FEM,a practical method of structure analysis of curved bridge is build when considering the sidelong support.
- The formulas for calculation of normal stress under complicated loads in a compo-site curved beam with general sectional shape are derived.
- Meanwhile, the springback potential energy principle is applied to calculate the springback deformation of a pure bending of curved beam.
- In this paper, the formulas for internal forces of skew curved beam bridges with arbitrary skew degrees are derived by using the principle of force-method in structural mechanics.
- The method for analyzing ultimate load capacity of steel curved beam with degenerated three-dimensional solid virtual laminated beam element is presented.
