Abstract

The paper presents an analytical model for estimating the composite action of prismatic reinforced concrete (r.c.) members repaired/strengthened by r.c. jacketing. The model considers the slip at the interface between the existing member and the jacket and establishes the mechanisms mobilized to resist this action thereby supporting composite behavior. An algorithm has been developed for calculating the response taking into account the shear phenomena that appear due to sliding at the interfaces as well as the spacing and penetration of flexure-shear cracks. Results calculated using the analytical model are corroborated with selected experiments from the international literature.
