Computer modeling of the thermal stress state of a concrete foundation slab of an educational institution building is considered. To simulate the thermal stress state, the specialized Midas Fea software package is used. The actual tensile stresses in concrete are compared with the maximum allowable values taking into account the equivalent age. It was established that the likelihood of cracking due to sudden changes in temperature is high, which entails the likelihood of destructive processes in concrete. Based on the calculations and modeling of temperature processes in concrete, it is proposed to use surface thermal insulation or to reduce the initial temperature of the concrete mixture in order to reduce the heat transfer rate of the concrete surface.
