Blikcharsky Z. The stress end strain state of reinforced- concrete constructions in aggressive environment at action of loading

The research results of corrosion of concrete, armature and of reinforced concrete beams experimental and theoretical at simultaneous action of aggressive environment and loading of different intensity are given. The characteristics of corrosion and changes of the cross-section form of the compressed concrete elements and reinforced concrete beams at action of loading are examined. It is offered to use the calculation of cross section which has the undamaged internal concrete and external layer of the concrete partly degraded by corrosion with the diminished descriptions of strength at the calculation of strength of the compressed concrete elements and reinforced concrete beams. Calculation methods of reinforced concrete beams on the basic of deformation model with the use of real diagrams.
