Evaluating the Effect of Non-Uniform Subsidence on Behalf of Steel Cooling Towers under Wind Load

Background/Objectives: This study was aimed to evaluate the effect of non-uniform subsidence on behave of steel cooling towers under wind load. Methods/Statistical Analysis: This study was done through Kato model and tower behave was studied after applying different loads. The tower height is 170 meters above the ground. The maximum radius was 60 meters at the bottom and the minimum radius was 36.5 in the upper part. Then the tower behavior were analyzed under loading in nonlinear static load cases. Findings: The results showed that the steel cooling tower had elastic behavior against the wind but components of lower levels of tower had plastic behaviour and eventually will lead to the destruction of the tower. Also the most tensions occures in the columns. Most effect and increasing of tension occur in columns with increasing the wind load. Balances No 5, 8, 15 are best balances for implementation the stiffener.
