| Abstract: |
The hybrid girder for a railway cable-stayed bridge consists of the steel-concrete composite girder at the main span and the prestressed concrete (PC) girder at the side span. The two spans are connected by the steel-concrete joint (SCJ) with multiply concrete filled steel cells (CFSC). The mechanical behavior of SCJ is investigated using three-dimensional finite element analysis (FEA). Results show that the internal force can be effectively transferred from the composite girder to the PC girder through CFSC without sever stress concentration. The two bearing plates remain the major force transfer components with the force sharing ratio of 60%, while both the shear connectors and the top concrete slab play important roles with the force sharing ratio of 20% respectively. The unique CFSC with extended force transfer path may improve the mechanical behavior of SCJ and is recommended for the application in the high-speed railway cable-stayed bridge. |
