Paper Title:
Seismic Damage Analysis of RCC Gravity Dams Using 3D Nonlinear FEM
  Abstract

The earthquake-resistance performance of gravity dam is an important indicator of dam safety. The earthquake-resistance performance of non-overflow monolith for Guanyinyan gravity dam is evaluated in this paper. First of all, the three-dimensional finite element model of dam is established by ABAQUS software. And then, the seismic response of gravity dam is analyzed by nonlinear finite element method, while the concrete damage plasticity constitutive model is adopted to describe the tensile characteristic of concrete. The seismic response and the damage evolution of dam are obtained. The results show that the dam has formed a crack-like band damage area at the end of earthquake, which are located in the dam along the dam-foundation boundary near the upstream face. At last, according to the results of simulation, the safety and the damage range are investigated.
