The paper presents experimental research results of prestressed shells’ operation features taking into account temperature load effect on the preliminary structure state. It is established that with an increase in temperature loads on the structure, the degree of tension in the prestressed structure changes downward. In accordance with the research carried out, with a change in temperature loads, the prestressed shell’s stress state decreased from 25% to 100%, depending on the temperature gradient. Thus, at a temperature gradient of 10°C in all models the prestressing indicator decreased by 1.25-1.35. At a temperature of 20°C, the indicator decreased by 1.67-1.75. At a temperature of 30-40°C, the indicator decreased by 2.35-5.98. At a temperature of 50-60°C, the prestressing in the structure on temperature loads decreased by 100%. Thus, the research results of the temperature load effect on the structure will allow to use prestressing in shell structures in more detail. It will be possible to use the results in construction and design, to improve the structure’s strength properties. This will allow to build a technology intensive structure effective for the operational environment. However, this research can positively enlarge previous research in this direction.
