Study on the integrated dynamic characteristics of a concrete gravity dam

The dynamic tests on an integrated model and a model with contraction joints were carried out in order to study on the seismic performance of Jinanqiao concrete gravity dam.Considered the influence of contraction joints and hydrodynamic pressure,the dynamic responses on the conditions of empty reservoir and full one of the concrete gravity dam are obtained.The results of tests are compared with ones of 3-D finite element analysis for the concrete gravity dam.Both of results are in good agreement.
