The bridge vibration problem would be highlighted due to flexibility of bridge when traffic is run on the long-span & high-tower continuous rigid-frame bridge. The finite-element (FE) software of bridge-vehicles coupling vibration theory was utilized to analyze traffic load influence on bridge vibration. It is found that the vehicle accelerations are varied greatly in the middle of mid-span and edge of side-span and vehicle bodies are plunged. According to the evaluating indicator of comfort level, people feel sea-sickness when vehicles run in design speed with fundamental frequency. Due to fundamental frequency of body in different speed, the sea-sickness feel will be stronger with lower speed. The impact action can be decreased by the increase number of vehicle-line load, and it is affected by the distance of vehicle-line load.

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.

A structure model of three-span continuous rigid frame bridge was constructed based on the finite element method. At first, the modal analysis was performed to get the natural frequencies and periods. The dynamic characteristics of the bridge structure were summarized, and some improvement measures are suggested to overcome the shortcoming for the bridge structure. Then, seismic response analysis was carried out based on the EL-Centro wave. The input excitations adopted the combination of vertical wave plus longitudinal wave, or vertical wave plus lateral wave. Based on the two excitation cases, some useful results were obtained, which include internal forces, displacements, accelerations time-history curves of the critical sections for the bridge structure. And some commentates about the time-history curves are given. At last, some helpful conclusions are drawn based on the calculation and analysis above. The calculation methods and results in this paper can provide some referenced information for the engineering design.

The Impact

The aseismatic performance of long span continuous rigid-frame bridge is an important but difficult research topic. To explore the impact of pier height and reinforcement ratio on long span continuous rigid-frame bridge’s aseismatic performance, Midas/Civil bridge Finite Element program is used to construct the three-dimensional model of a continuous rigid-frame bridge in this research. Fiber element and plastic hinge are used in pier simulation. Through the adjustment of pier height and ratio of reinforcement, the internal force, displacement and plastic rotation of bridge pier’s critical sections are analyzed under the action of seismic loading. Thereby, the impact of pier height and plastic hinge on such bridge’s aseismatic performance is obtained. It is shown that: maximum displacement, bending moment and plastic rotation increase at pier cap with pier height, indicating that pier height has strong impact on seismic response. And with increasing reinforcement ratio, the bending moment and yielding moment at pier cap and base both increase. Therefore, suitable pier height and reinforcement ratio should be selected for better aseismatic performance.
