Abstract
In recent years, with the rapid development of transportation in our country, the study of curved bridges has become more advanced. The static analysis of curved bridges has been almost perfected, but research on the dynamic effects is still immature. In this paper, a five-span continuous curved box girder bridge is used as the subject. The ABAQUS finite element software is utilized to construct the bridge model, while the three-dimensional representation of the tire is created using SolidWorks software. The effects of vehicle speeds, loads, and eccentricity on the dynamic response of a curved bridge deck are studied using a tire model. The research shows that the maximum dynamic deflection in a bridge span increases gradually with the increase of vehicle speeds, but it does not increase in a linear manner. Additionally, the dynamic deflection of the bridge in the mid-span is greater with larger vehicle loads. Furthermore, the dynamic deflection, cross-section moment, and strain response of each span increase as the vehicle eccentricity increases.
