Abstract
Vibration effect analysis was carried out in order to investigate environmental vibration of the resonance shaking table introduced for high acceleration shaking tests. Based on past ground survey results and design information of shaking table, a detailed three dimensional analysis model was created and wave propagation analysis was performed. The analysis result agreed with the vibration level data measured at the trial operation of the resonance shaking table. The acceleration distribution in the surrounding ground was visualized by volume rendering, the environmental vibration behavior of the surface wave and the body wave was clarified. These results would be utilized for the solution of vibration problems occur in the future.
