	A methodological approach is proposed for detecting the behavior of welded structures under thermomechanical influences with high reliability of results using computer modeling experiments. A series of samples were produced from a batch of rolled angle bars with dimensions of 25x25x4. By applying standardized methods on the certified electro-hydraulic testing complex STM-100, experimental investigations of the mechanical characteristics of VSt3ps steel were conducted both at room temperature and within the range of technological and fire temperatures. The obtained results were subjected to statistical analysis, and an input data array for the ultimate strength and yield strength of VSt3ps steel was formed within the temperature range from +20 to +450°C. It was found that the research results follow a normal distribution law. The scattering of values for the ultimate strength is 2.1%, and for the yield strength is 2.6%, which is significantly lower than the information provided by Ukrainian National Standard and quality certificates of the material.
