The Role of Geometric Imperfections in the Collapse of a Cooling Tower

Effects of geometric imperfections in the form of the meridians of hyperboloidal cooling towers are re-assessed. It is shown that even moderate imperfections induce hoop stresses in the vicinity of the imperfection that are of the same order of magnitude as the meridional stresses that would occur in this same area of the perfect shell.
