Massive reinforced concrete structures at the construction stage experience a complex stress-strain state due to uneven thermal expansion caused by heat releaseduring the exothermic reaction of concrete. The purpose of the article is to study the main factors that should be taken into account when constructing models forcalculating massive reinforced concrete structures at the construction stage. The main factors determining the temperature and stress-strain state of concrete aresummarized. Recommendations on the compilation of design models, the use of the necessary software, as well as on the establishment of individual parameters set inthese software complexes are made, the admissibility of dividing the associated temperature-strength problem into two subtasks - temperature and strength is shown.The significance of the results obtained are in the possibility of compiling similar computational models with arbitrary dimensions, shape and boundary conditions.
