Abstract

In the proposed article, using computer modeling based on the finite element method, an enclosing structure is investigated, the reinforcement of which is made by using a steel cage. The aim of the study is to analyze the effect of the adopted amplification option on the change in the temperature field in the thickness of the enclosing structure. As part of the study, two models of the enclosing structure were considered: the first – with a reinforced steel cage, the second – without reinforcement. As a result of the analysis of the results obtained, the need for additional thermal engineering calculations of enclosing structures, when performing their reinforcement, was shown. It was also pointed out that in this case, the reinforcement elements of the enclosing structure, which further increase its thermal heterogeneity, are recommended not to be divided into similar fragments, since they can influence each other, which leads to a change in the temperature field in the structure. In the case of division into similar fragments, the calculation results obtained may not be correct, since this effect may be significant in the accepted amplification variant.
