Investigation on Buckling Behavior of Cylindrical Liquid Storage Tanks Under Seismic Excitation: 2nd Report — Investigation on the Nonlinear Ovaling Vibration at the Upper Wall

Abstract: When a thin walled cylindrical liquid storage tank suffers a large seismic base excitation, buckling phenomena such as elephant foot bulge at the bottom portion and nonlinear ovaling vibration at the upper portion shows nonlinearity between the input and response level and suddenly occurs for the excessive input level, thus will be called as “nonlinear ovaling vibration” hereafter in this paper, may be caused. In the 1st report, the elephant foot bulge phenomena and the liquid pressure effects were investigate… Show more

“…The buckling at the top of a tank due to earthquakes has frequently been attributed to the sloshing component of the hydrodynamic response of the tank-liquid system [13]. However, both Morita et al [12] and Natsiavas and Babcock [9] proved that this buckling mode arises mostly from the impulsive action of the hydrodynamic response of the liquid; the sloshing action may contribute to the occurrence of this type of buckling, but it is not the main cause.…”
