Abstract:

Non-linear finite element analysis is used to study the elastic stability of cylindrical storage tanks subjected to unsymmetrical loads. These cylindrical shells are assumed to be fixed at the bottom and closed at the top. The storage tanks under study have length to radius (L/R) ratios of 1, 2, and 4; and radius to thickness (R/T) ratios of 500 and 1000. The shells also have rectangular and circular cutouts which are located facing the wind direction (? = 0?), and perpendicular to the wind direction (? = 90?). The sizes of the cutouts considered in this study are 15?, 30?, and 45?. The buckling loads and maximum deflections at the buckling loads are found from the analysis using the ANSYS computer program.
