| Abstract: | Composite box girder with corrugated steel webs is a new type of bridge structure. This structure, which can both reduce the weight of dead weight and show all the performances of the other materials, is the substitute of the traditional type of concrete web or the flat steel web. By analyzing the longitudinal stiffness and the axial stiffness of corrugated steel web, the formula of bending resistance is made. And the calculation formula of bearing capacity is deduced according to the research achievements from abroad and domestic. |

| Keywords: | corrugated steel web composite section axial stiffness bending resistance bearing capacity |
