This paper deals with the influence of the shape of covering at smokestack to the resultant of load from wind effects. Calculation according to current standard takes into account only size of the wave-height of shaped sheets regardless of the shape of the waves, which leads in some cases to a substantial increase of the coefficient of force. The aim of this paper is to determine the equivalent coefficient of force for a cylindrical shape smokestack, which is covered with corrugated iron. The flow around smokestack is designed in software Ansys Fluent using the DES model. The calculated coefficient of force for the real roughness of a smokestack is compared with the values specified in the standard.
