Four halls with various dimensions and gable roofs were subjected to characteristic loads in compliance with the Eurocode and to wind loads, using two approaches. In the first case, standard provisions were followed, while in the second, CFD wind flow simulation was performed in the RWIND 2 program. Based on the results, it was proven that the structures designed according to standard provisions provide approximately 50% reserve of load-bearing capacity, compared to the same structures loaded according to the experimental numerical approach. When evaluating theresults obtained, it was noticed that the location of the most stressed cross-sections of the structual elements differs, depending on the loading method used. This fact is most likely related to the adopted RAS k-ε turbulence model, which has numerous averages, but is the most advantageous model in terms of the time spent on simulation.
