Stress Analysis of Prefabricated Skew-to-normal Bridge Structure
Due to the influence of road conditions under the bridge and economic factors,the application of skew-to-normal bridge is more and more widely.The length of each beam in the same span of the skew-to-normal bridge is quite different,and it is usually subjected to the bending-torsion coupling.The stress situation is much more complicated than that of the orthogonal bridge.It is necessary to analyze the stress situation of each beam when designing the bridge.Taking an expressway project in Guangdong as the background,this paper establishes a grillage model of prefabricated skew-to-normal bridge on the expressway for stress analysis,and then guides the design of the skew-to-normal bridge.The feasibility of the prefabricated skew-to-normal bridge in expressway construction is verified through actual project cases,aiming to provide reference for similar projects in the future.
