Dynamic Characteristic Analysis of Long Span Cable-Stayed Pipeline Bridges

In this paper, the dynamic characteristic of a new type of structure long span cable stayed pipeline bridge is investigated from the establishment of the dynamic analysis model, comparison between the computed results and the test results, comparision with common calbe stayed bridges. The conclusion indicated that the initial internal force caused by the dead weight of the cable stayed pipeline bridge has a great influence on the dynamic characteristics of the bridge. The dynamic characteristics of the cable stayed pipeline bridge are different from that of the cable stayed bridge, although having similar structural type.
