Curvature radius is one of the key design parameters of curved cable-stayed bridges. In order to obtain the influence law of curvature radius on the static and dynamic characteristics of curved concrete cable-stayed bridge with Π-shaped girder, taking a long span curved cable-stayed bridge as the engineering background, one spatial beam and plate mixed finite element model was established. Based on the theoretical model, the influence of the curvature radius on the structural static characteristics and the dynamic characteristics was analyzed by comparing curved cable-stayed bridges with different curvature radius and straight cable-stayed bridge with the same span. The results show that there is a big influence of curvature radius on the static and dynamic characteristics. The research results can provide some reference for the design of similar bridge structures. |
