- Abstract
The effect of the wind load is predominant on the tall and large structures like cooling tower. The study on the deformation of the critical sections of the shell element in the large structures like cooling tower has been skipped on most of the previous research. This paper presents the ovalization pattern of the cooling tower shell in different mode shapes when subjected to axisymmetric wind loading. This paper studies two different models of cooling towers: the 1st model is located in Andal West Bengal, India which is fully hyperbolic in shape, and the 2nd model is the modification of the 1st cooling tower which has the cylindrical portion above the throat level of the 1st cooling tower. Simulation of the cooling tower has been done using the finite element software ABAQUS, the wind load that has been described in the relevant Indian Standard Code has been expressed in terms of Fourier series using the advanced options available in the software. The cross-section distortion of the cooling tower shell in the nonlinear range of the elasticity in different mode shapes has been studied. A comparison of the two types of cooling tower models in terms of stress, displacement and strain is made in this study.
