Abstract
The hybrid girder cable-stayed bridge of railway has been applied in the design of the Yongjiang Bridge, it is first used in our country as yet. The mechanical performance of the steel-concrete joint as the key position of the hybrid girder cable-stayed bridge determine its safety and durability. Based on the background of a bridge in Zhejiang Province , the spatial finite-element model of model and actual bridge is developed to study the mechanical performance and verify the feasibility of design method of the model. As it turned out, the model can better reflect the stress of actual bridge. The trend of the stress of the key plates of its is basically identical. The steel-concrete joint can perfectly accomplish the transmission of the stress function. Bearing plate plays a vital role in the stress transfer, the function of the PBL shear connector near the bearing plate is obvious.
