Monitoring thermal stress state during concreting of massive foundation structures for high-rise buildings

The article outlines the core principles of monitoring the thermal stress state during the concreting of massive concrete structures, using the foundation systems of high-rise buildings in a planned complex in Saint Petersburg as a case study. The study aims to develop methods for controlling the thermal stress state during concreting by establishing criteria for concrete crack resistance. To achieve this goal, calculations of temperature fields in the concrete structure during the hardening phase were performed, and crack resistance criteria were determined. The key findings of this research can be applied to the design and construction of massive foundation systems for unique buildings and structures.
