| Abstract: | Combine with the concept designing of the prestressed concrete truss bridge, the response of the truss bridge subjected to static load was analyzed based on the stiffness matrix and ANSYS finite element numerical model. By the analysis of the deformation and stress of the web members and chord members, mechanical characteristics of the bridge were researched. Optimized design program of truss bridge was proposed. |
