n this paper, eights one-span single-storey industrial steel building frames with cranes were investigated withthe parameters on frame spans of 20, 26, 32 and 38 m; crane capacities of 100 and 200 kN and constructionlocations in Hanoi and Son La regions. Load cases to be used for design of the frames included dead loads,roof live loads, crane loads, horizontal and longitudinal wind loads, and equivalent horizontal and verticalstatic earthquake loads. Numerous cases of internal force combination were defined in accordance with thecombination coefficients when considering that the earthquake load had a major influence, the wind load had amajor influence and the wind load had the same effect as the other live load activities. As a result, the bendingmoments at the bottom and top of the column combined due to the earthquake load tended to be larger thanthose combined due to the wind load when the span of the frame increases, especially for the case of framesconstructed in the Son La region with strong earthquakes and weak winds. In addition, the weights of the framecolumns and beams designed to withstand the earthquake loads were considerably greater than those designedto the wind loads, depending on the span lengths and relative magnitudes of the earthquakes against winds
