Abstract
Since earthquake resistance performance required for a dam during large-scale earthquakes is to ensure reservoir functions, a spillway gate is important associated facility to satisfy the earthquake resistance performance. However less actual observation records on dynamic behavior of the gates during earthquakes than those of dams has been collected before, therefore the behavior enough for evaluation of the earthquake resistance performance of the gates are not identified.
Based on such background, in this research, the vibration tests and the earthquake observations for gates of a concrete gravity dam, which aim to obtain basic information on the dynamic behavior of the gates during earthquakes, were implemented. And then, the eigenvalue analysis by using the three-dimensional FEM Model and the simulation of the earthquake observation records were implemented, and the analysis model to be applicable for the evaluation of the earthquake resistance performance of the gates was developed based on the results of the simulation.
