The wind load on the building depends on its shape and size, type of terrain, climatic region and a number of other factors. In accordance with Russian standards for buildings with a high level of responsibility, it is required to determine the wind load either experimentally in a wind tunnel, or using numerical simulation by solving three-dimensional problems of fluid dynamics. The article presents the results of the numerical determination of aerodynamic coefficients for the building of the steelmaking shop, made using the Abaqus software package. The steelmaking shop has a complex shape in plan and uneven in height, it is a particularly dangerous production facility and refers to structures with a high level of responsibility. The aerodynamic coefficients on the walls and roof of the steelmaking shop obtained by CFD analysis are represented. The different meshes are analyzed. Regulatory method to calculate aerodynamics coefficient also may be adopted for this building. The values of the coefficients by regulatory procedure are on average greater than those numerically obtained. The wind load does not have a significant effect on the framework of the steelmaking shop, since the efforts from the wind load are not more than 10% of the maximum total effort in the elements, while the efforts from the crane load are up to 45% of the total effort, and from the technological loads up to 50% of the total effort. So, using the regulatory procedure for bearing capacity analysis of framework of the steelmaking shop is also possible.
