From Professor Wilfried B. Krätzig. Professor Krätzig writes: "I personally have been engaged in the last 40 years more and more with the design and construction of large reinforced concrete shells, where buckling is not the most urgent issue, rather nonlinear responses combined with local instabilities. [Here is] some information on these works related to the largest shell structures which presently exist on earth: cooling towers."
"Large Shell Structures for Energy Generation – Challenge for Shell Stability: Natural Draft Cooling Towers serve for re-condensation of the worked-off steam in steam power plants. They are presently the world-largest shell structures, made of high-performance reinforced concrete. The world's highest cooling tower in Niederaussem Power Plant raises up to 200m of height, has a bottom diameter of 152m and a wall thickness of about 0.24m. This slide shows two cooling towers at Neurath Power Plant with heights of 190m."
