ABSTRACT
Over the past 35 years, much research has focused on the buckling of Natural Draft Concrete Cooling Towers, primarily in the form of hyperboloids of revolution. Most of this work was stimulated by the failures of cooling tower shells in Great Britain and also by the increasing height of new towers. The goal of this paper is to review some relevant publications and to present new results. We have chosen to focus attention on one of the most widely studied shells, the Trojan Tower outside of Portland Oregon USA, situated on the Columbia River. The Trojan Tower still stands, even though its accompanying power plant ceased generating power in late 1992.
