| Abstract: | Using ansys finite element analysis software,the dynamic characteristic of half-through steel truss self-anchorage suspension bridge is analyzed. Present the accurate modeling method, which can be satisfied for project analysis precision requirement. List the representational vibration characteristics of the new bridge type and analysis it, the result can provide practical dynamic characteristics basis for engineering practice. |
