| Abstract | The main objective of this study is to impr ove the knowledge in the seismic analysis and design of concrete gravity dams thr ough experimental and numerical works. This study is divided into two main works: experi mental and numerical seismic analyses of concrete gravity dam and development of BEM for nonlinear dynamic analysis. In the first part, the shaki ng table tests were conducted on two small-scale models (Model#1 and Model#2) of a concrete gravity dam, which has been planned for the construction with the recommendation of th e peak ground acceleration of the maximum credible earthquake of 0.42g. The development of bentonite-concrete mixture material, which matches the similitude requirements between the prototype and the model, is discussed. Two types of excitation, resonance test and ambient test, were conducted to investigate the resonant frequency, the maximum failure acceler ation and the crack initiation/propagation. In both models, large amplification was observed at around 24~28 Hz. The crack initiated at the slope changi ng point and then propagated around the neck area. The crack failures were occurre d at the base acceleration of 0.55g~0.65g. |
