| Abstract: | The two kind of three-dimensional finite element model is established and the natural frequency and modes are calculated,additionally the influence of primary structural parameters to the self-vibration characteristics is analyzed through the application of the finite element analysis software,and analyse self-vibration characteristics of the bridge comparing with a coequal span tied arch bridge.The calculating results and conclusions of the paper can offer the related technical parameters and basic data for the design certification,construction,health detection and maintenance in working conditions. |
