Annotation:
The article presents a diagram method of calculation of reinforced concrete slabs. The considered flor slabs were subjected to intensive inflence of climatic conditions of Moscow, as a result of which they received diffrent schemes of damage. The bearing capacity of these plates varied depending on the scheme (section) of the plate damage. At the same time, concrete tests of damaged sections of structures, as well as corrosion-damaged reinforcing bars were performed. The diagrams of concrete deformation of undamaged and damaged areas and the diagrams of stretching of damaged reinforcing bars are obtained. On the basis of experimental diagrams of concrete and rebar deformation, a method of analytical determination of the bearing capacity of the plates was developed.
