In this article a method of Finite Element modeling the roof of a stadium in SCAD Office as a three-dimensional structure is considered. The stress-strain state of the supporting framework of the roof is analyzed paying attention to different loads contribution. Following the results of the investigation the shape of the roof is optimized by the criterion of metal consumption.
