Application of the theory of compound cores for the assessment of stress pattern in the cross section of a strengthened beam column

Abstract

© Published under licence by IOP Publishing Ltd. The article considers the results of theoretical studies of the stress-strain state of an eccentrically compressed element reinforced with a reinforced concrete cage. The theory of composite rods is used as a theoretical basis. As a result of the solution of the theoretical problem, analytical expressions are obtained for determining the normal stresses in the cross-section of the reinforced element and tangential stresses along the contact seam. The results of the calculations for the proposed approach are compared with the previously performed research results.
