| Abstract: |
| At present, when computing the wind-induced response of the large-scale cooling tower, the obtained wind pressure distribution is imposed on the tower structure to perform structural analysis, and the variety of wind load caused by the deformation of cooling tower is not considered, which may result in some error. In this paper, the analysis of wind-induced responses of the large cooling tower based on the iterative method is studied, in which the advantages of computational fluid dynamics (CFD) and finite element method (FEM) are combined in order to improve the accuracy, and the influence of the air inside the tower and the water distribution system on the structural response is discussed. The comparative study between results obtained from the code regulations and the proposed iterative method is conducted, their difference becomes larger with the increment of the average wind speed. |
