The Application Study of Non-Linear Dynamic Contact Model of Arch Dam with Contraction Joints

Abstract

Based on the theory of contact force, 3-D frictional contact non-linear dynamic contact model was put forward. It got across to search contact face, and ensure contact state. In succession, it asked for contact force under satisfying contact condition and dynamic balance condition. With the earthquake loading, the model simulates opening, closing and sliding of arch dam with contraction joints.
