A comparison study is presented of the analysis of ring sections of cylindrical tower structures subject to the effects of temperature gradient and wind loading. Five different assumptions were made regarding section stiffness, reflecting a number of approaches from U.S. and European practice, which lead to computations of a wide range complexity. Results indicate that deflections and crack widths can only be predicted realistically if the sensitivity of temperature effects to stiffness is considered. The interaction between temperature effects and wind loading can be neglected. Regarding structure strength, redistribution of moments due to cracking increases the carrying capacity and should be considered. Suggestions are made regarding choice of assumpions for analysis which strikes a reasonable compromise between reality and simpliticy.
