Abstract: The contraction joints have to be modeled if the open-close effects of joints on the dynamic response of high arch dam are studied.Based on the strain rate-dependant damage constitutive model,the dynamic response and the damage characteristics are studied for the arch dam model with and without considering the opening-closing effects of joints.The analysis show that arch dam model without modeling contraction joints can give reasonable dynamic response results based on the nonlinear concrete model.
