SOME STRENGTHS FOUNDATION SLABS.

Various ways of strengthening foundation slabs are analyzed in relation to cases when, after the construction of foundation slabs, as a result of project adjustments, the load on them increases. An example of the implementation of the reinforcement of the foundation plate in the case of an increase in the number of storeys of the building from 10-14 floors to 17 is given. The effectiveness of various ways of strengthening foundation slabs is investigated by the example of the regional children’s clinical hospital under construction in Tver. The methods of reinforcement of foundation slabs are conditionally divided into two groups within the framework of constructing a finite element computational model. The first group includes methods that compensate for the lack of upper stretched reinforcement of the foundation plate by sticking on the surface of problem areas of steel or carbon fiber tapes. The second group includes a method that redistributes bending forces in the foundation plate from more loaded to less loaded sections. Methods of modeling of sub-columns in the computing environment of the LIRA-CAD software complex are investigated
