ESTIMATION OF BULGING RESPONSE OF ISOLATED RECTANGULAR WATER STORAGE TANK

Abstract

To investigate the applicability of a mechanical model to estimate the bulging response of an isolated rectangular water storage tank, sweep excitation and scaled real earthquake-wave excitation were performed on a model tank with various liquid levels and its response was measured. A comparison of the response value calculated by the mechanical model and the results of excitation tests showed that the mechanical model is effective in predicting the waveform and peak value response characteristics of the isolated tank.
