Abstract
The purpose of the numerical and analytical studies was to analyze the annual temperature deformations of the long-span coating of the Sports Arena building in Tyumen. The structure of covering is made of 1915 grade aluminum alloy and is operated outdoors. Annual differences in outdoor air temperatures led to significant temperature deformations of the building covering in the transverse direction. Comparison of the obtained calculated values of thermal deformations of the roof trusses with the normative limit values made it possible to conclude that the bearing structure of the covering is poor from the point of view of perception of climatic influences. The use of classic approaches to the design of building coverings inside the thermal circuit makes it possible to significantly reduce the risks of defects and damage to structures during their long-term operation.
