Influence of Fixed End Constraints on the Mechanical Performance of a New Column-Slab Hollow High Pier

The column-slab hollow pier is composed of frame column and thin-walled slab, which is a new pier structure for the design of long-span bridge piers with high intensity. Its force is different from that of solid pier and traditional hollow pier. The connection between the hollow segment and the solid itd on the top of the pier and the connection between the solid segment and the base solid segment is affected by the constraints of the solid segment and the fixed end of the cap. Column plate hollow high pier is a new type of structure, the influence of the fixed end interference stress research is quite scarce, to explore the influence of the fixed end pier interference stress level, this paper USES the finite element model and the bar system finite element entity model of the new column plate fixed end of bridge pier interference stress was analyzed, and provide reference for the design and calculation of the bridge pier.
