Abstract

An example of a high-rise building behavior calculation shows that weather deformations of concrete have a significant contribution to changing the behavior of vertical load-bearing elements - columns and walls. The phenomenon of different shrinkage of concrete/steel pillars and concrete core due to the shrinkage and creep of concrete over time is pointed out. These shrinkages may have negative consequences on the usability of the structure, the filling elements, the installation in the building, etc. The calculations are made using a budget model developed by the author as a part of the more detailed paper on the analysis of the rheological properties impact in complex composite structures with layered finite elements.
