The problem of strengthening the building structures of operated buildings and structures is relevant in a developing economy. The design of strengthening and the structural analysis of strengthened structures is especially difficult when strengthening is performed under load, since it is necessary to take into account the stress-strain state of the original structure. The article presents the results of an experimental and theoretical study of bent reinforced concrete elements, strengthened under load by an increase in the cross section by building up additional concrete in the compressed zone. On the basis of the general deformation analytical model, a technique for strengthened under load bending concrete elements is proposed, based on our own experimental studies, the proposed technique is verified.
