Abstract：Lots phenomena of pounding damage between the superstructures of the bridge occurred in the earthquake. Lots of models used to simulate impact effect between bridge superstructures are presented, which include impact-restitution method, Lagrange multiplier method and contact-element method. The contact-element method includes the linear spring model, Kelvin model, equivalent Kelvin model, updated Kelvin model, Hertz model, Hertz-damp model, 3D contact-friction model and nonlinear viscoelastic model. The advantages, disadvantages and application scope of various models are compared. And the influence factors of pounding are summarized.
