Seismic Performance Analysis of Continuous Rigid Frame Bridge with High-Piers and Long-Span
The dynamic characteristics of Tukan Wujiang Bridge are analyzed numerically. The bridge, which is still under construction, is a continuous rigid frame bridge with high-piers and long-span in Wulong County, Chongqing, China. A spatial finite element model is established for the bridge with the finite element software ABAQUS. The natural vibration characteristics and effective modal participation mass of the bridge in the built-up case is obtained. The variation of dynamic characteristics of continuous rigid frame bridge subjected to the dynamic earthquake loading is studied, and the number of modes necessary to the vibration mode combination when applying the response spectrum method under the earthquake is obtained. In addition, the seismic response of the bridge is analyzed with both the response spectrum method and the time-history method, and the maximum response of structure under various probability of earthquake is obtained. The results of the two methods are compared. The comprehensive seismic performance of the bridge is analyzed and evaluated. The results show that the seismic performance of the rigid frame bridge satisfies the expected design performance.
