Abstract

In Japan where the earthquake occurs frequently, it is very important to examine bucking strength of large thin tanks under seismic excitations, but few data for the buckling of tank filled with fluid are found because of the difficulty of experiments. In this research, experiments of cylindrical containers filled with water storage are conducted. The compression stress and the buckling deformation tanks are investigated in these experiments using small tanks made from polyester sheets.
