Absract. Construction and operation of buildings and structures are always accompanied by the appearance of various defects and damages of building constructions. Solving such problems makes it possible to provide required mechanical safety performance and durability in the further usage. The article describes the state of normative documents in the field of repair and strengthening of reinforced concrete structures, it reasons the development a new code of rules "Concrete and reinforced concrete structures. Rules of repair and strengthening" devoted to designing the repair of concrete and reinforced concrete structures as a whole, and strengthening heavy concrete structures of buildings and facilities of different purposes. The main provisions and key requirements of the new standard are presented. The developed code of rules will enable specialists to make reasonable solutions determining the volume of repair required for reinforced concrete structures, design rehabilitation measures as well as to provide the economic efficiency within the reduction in operation cost and extend inter-maintenance periods for existing and newly constructed buildings and structures.
Key words: code of rules "Concrete and reinforced concrete structures. Rules of repair and strengthening", reinforced concrete structures, repair, strengthening, durability, defects, damages, standardization. - REFERENCES
