Nowadays, designers are able to create an accurate and complex engineering design by effective mathematical models. The paper describes the numerical analysis of cooling tower carried out by a finite element method. The FEM analysis was performed with Lusas software. The cooling tower represents the real structure located in Kozienice, Poland. During the calculations, different load cases based on wind tunnel tests were taken into account. The evaluation of the influence of different wind directions and configuration of obstacles on internal forces and displacements were analyzed. Proper dimensions, material proprieties and method factors were applied to the model. In the further part, the dynamic evaluation was presented. The Eigen modes with corresponding values and shapes were created and described. Estimation of impact of dynamic wind action on the object will be also released. Time history of amplitude and displacements was attached. As a result of the dynamic studies, the dynamic evaluating indicator was calculated.
