The article presents the results of an experimental and theoretical study of bent reinforced concrete elements under the action of a static load. Experimental bending elements were brought to destruction and then restored with the replacement of the section of the deformed working reinforcement. Several test slabs were rebuilt with a new section of rebar prestressed. The features of work under load of bent reinforced concrete elements restored after destruction are established.
 
 Performed, on the basis of the general deformation model of the cross section, modeling of the stress-strain state of the restored bending reinforced concrete elements. Comparison of the calculated main parameters of the stress-strain state with their experimental values showed satisfactory convergence.
