Dynamic Analysis on Continuous Steel Truss Girder of Combined Bridge

By means of Midas Civil, a software of finite element model, some steel truss combined bridge was discrete simplified to develop a finite element model; then followed by an analyses on both the dynamic property of the model, which results in the values of vibration mode and natural frequency of vibration, and the dynamic properties of railway-section as well as combined bridge, so that the transformation rule and actual stress situation of the combined bridge can be well learned.
