About need of calculations for the steel framework building in temperature influences conditions

In the article a technique of studying technical condition for steel structures that were damaged by high temperature impact, as well as a climatic effects on building structures due to the difference in ambient temperatures is described. Based on obtained data, there was made a conclusion about technical condition of the structures and possibility or inability to restore their serviceability by repair, reinforcement or replacement. There were conducted a comparative analysis of the results of experimental studies and numerical analysis. The mathematical model makes possible operative prediction for the controlled parameters values of building structures. In the article, examples about practical application of the techniques are described that allow doing technical examination of objects, damaged by temperature influence. The aim of this study is to substantiate the need to make calculations about temperature impacts for buildings with a steel frames and to develop measures to ensure the serviceability of steel structures of buildings and structures in conditions of temperature impact.
