The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without cutouts are considered, one open at the top and the other closed at the top. The cylinders with cutouts are closed at the top. The present investigation finds the buckling loads of circular cylinders with and without cutouts. The cutouts are placed in the windward direction and at right angles to the windward direction with the rectangular cutout openings making angles of 15 degree and 30 degree at the center of circular cross-section.
