Seismic Safety Evaluation of High Arch Dams Using Concrete Damage Theory
To reasonably evaluate the seismic behavior of high arch dams, a damage plasticity model is adopted to simulate the dynamic nonlinear behavior of dam concrete for a hydropower station. Combining with the viscous-spring boundary and compressibility reservoir model, the maximum principal stress on upstream and downstream surfaces is obtained. The results show that the effects of material nonlinearity damage on the dynamic response of the arch dam are significant under earthquake load.
