Abstract

An analytical algorithm for solving the nonlinear bending deformation of a thin-walled hollow bridge pier under the action of water flow considering the fluid-structure coupling effect, is proposed. Initially, The kinematic equation and the dynamic equation on the wetted surface of the structure are established by using the united Lagrangian-Eulerian(ULE) method. Afterwards, based on nonlinear bending theory of elastic shell and potential flow theory, the coupled mathematical model of a flexible pier and surrounding water, is presented. Finally, in a specific example, comparative study is conducted between the analytical solutions and the numerical solutions computed by ANSYS combined with CFX (two-way coupling) in ANSYS Workbench, and the analytical algorithm is verified to be feasible.
