description: Object of research: In this work, the calculation of the thermal stress state of the concrete foundation slab of the reactor compartment of a certain nuclear power plant during the construction period is carried out. Reinforced concrete foundation slab made of B30 concrete, thickness 2.6m, width 10.5m. The slab rests on a layer of concrete preparation B12.5 on a soil base. The outside air temperature is 15Â°C, concrete mix 20Â°C.Â The purpose of the work: The purpose of this work is to obtain the results of taking into account the fact that in the process of heat release of massive concrete and reinforced concrete structures in the calculations of the thermal stress state and crack resistance during the construction period. It is also necessary to carry out calculations of the thermal crack resistance of a massive slab with an updated technological change in the heat release of concrete over time.Â The tasks of the work were: Task This dissertation is reduced to the analysis of calculations using the TERM program for a concreted massive foundation slab. The relevance of the topic is due to the fact that the use of reinforced concrete in the construction of critical buildings requires solving the problem of thermal crack resistance of massive monolithic structures erected in conditions both favorable and contrary to temperature.Â The novelty of the final work: analysis of the theory of heat release described by I. D. Zaporozhets, which is still relevant today, as well as its adjustments for contributions to events for the departure of concrete. The practical sensitivity of the master's thesis results in the analysis of temperature changes and the thermal stress state of a concrete structure.In the master's work, the fundamental slab of the nuclear power plant reactor compartment is restored as an object prepared to determine the thermally stressed state as a critical structure.
