description: Now, when designing and building massive concrete and reinforced concrete structures of critical and unique buildings and structures, big attention was paid to the regulation of the temperature regime the construction period. In this paper, pipe cooling was studied as a method for regulating the thermally stressed state.
Tasks that were solved during the research:
1. Description of the algorithm for calculating the temperature regime of a massive concrete structure;
2. Analysis of temperature fields and stresses and deformations in the structure;
3. Calculation of the thermal stress state of the structure under different modes of pipe cooling;
4. Analysis of changes and determination of temperature cracks with changes in the pipe cooling mode;
5. Finding safe modes of concreting objects using cooling systems.
In this masterâs thesis, calculations of the thermal crack resistance of the foundation plate of the reactor department of the Turkish NPP Â«AKKUYÂ» under the influence of pipe cooling on the thermally stressed state. Calculations carried out taking into account the effect of hardening temperature on the thermophysical and deformation normative characteristics of concrete. Based on the results of the analysis of design studies, the optimal technology of pipe cooling of the foundation plate is selected to ensure thermal crack resistance of the structure.
