INVESTIGATION OF VELOCITY RESPONSE SPECTRUM PREDICTION FORMULA FOR SLOSHING DAMAGE EVALUATION OF WATER RECEIVING TANK

Abstract

 In this study, in order to evaluate the sloshing damage of water receiving tanks during an earthquake, we evaluated a pseudo-velocity response spectrum prediction formula for natural periods of 1 to 5 seconds corresponding to the fundamental sloshing natural period of water receiving tanks in the Kanto region. As a result of obtaining the pseudo-velocity response spectrum prediction formula by two-stage regression analysis, we were able to evaluate the observed values with high accuracy. Furthermore, using the obtained prediction formula, we evaluated the pseudo-velocity response spectrum and sloshing wave height of the receiving tank and evaluated the damage of the receiving tank container for the scenario earthquake.
