摘要：

The nonlinear seismic behavior of arch dams with reinforced contraction joints is one of the key topics in arch dam engineering. The behavior of an arch dam model with brittle materials and reinforced contraction joints was investigated in shaking table tests with harmonic loadings and earthquake waves. The same dynamic process was then simulated with the finite element program of ADAP-88 in which the strengthening effect of the contraction joint reinforcement can be considered. The numerical results agree well with the experimental data. The test results show that the contraction joint openings are significantly reduced by the reinforcements and that the arch dam integrity is obviously improved.
