 Summary:
 Wind actions can be dissolved into two components: steady or mean action, and gust or variable action. The first component produces static load on structure, but the second produces dynamic load. The dynamic component depends on meteorological data for gusts in certain region, and on internal characteristics of the structure. Dominant design approach is to treat wind action generally as a static load. This may be unjustified for high, slender, and flexible structures like steel towers. The paper is analysing the response of a specific steel tower structure on wind actions using static approach first, and then superimposing static and dynamic load. FEM was used as a method of analysis. Results and recommendations for further treatment of similar structures are given as a conclusion.
