Abstract:Thin wall hollow high pier is suitable for a variety of complex terrain and has considerable flexibility, which can better deal with the deformation of superstructure. At the same time, its hollow structure can greatly reduce the engineering materials and its own weight, and is widely used in high pier bridges. In this paper, the spatial beam element model of pier body is established by using ANSYS software. Considering the influence of temperature effect, the changes of pier top displacement and pier bottom bending moment caused by the consideration of geometric nonlinear characteristics of thin-walled hollow high pier are analyzed. This paper lays a certain foundation for the structural safety control of thin-walled hollow high pier in the design process, which can be used as a reference for similar bridges.
