000012685 520__ $$2eng$$aAn understanding of the buckling behaviour of cooling towers in response to changes in shell geometry is of paramount importance. In this paper, a linear eigenvalue buckling analysis is presented for various cooling tower shell geometries. The shell is subjected to increasing wind speed, and the critical wind speed (at which the shell first buckles) and corresponding buckling mode are observed, as the geometric parameters of the shell are varied through the practical range for industrial cooling towers. It is observed the variation of critical wind speed with cooling-tower height is similar to the Euler buckling curve for axially-loaded struts. There appears to be a certain optimum throat-height to total-height ratio (about 0.75) at which the critical wind speed is a maximum. The critical wind speed is observed to vary linearly with the cooling tower thickness, and non-linearly with shell-diameter parameters. The results may be used as a basis for the preliminary design of cooling towers against wind-induced instability.
