A technique which is used to increase the flexural capacity of weak reinforced concrete elements is the addition of a new concrete layer. As a result, a new composite element is produced and its behaviour depends on the connection between the old and the new concrete. As a result, the behaviour of the composite element is controlled by the sliding at the interface. The present paper presents an analytical procedure in order to calculate the sliding distribution at the interface of a reinforced concrete beam which is strengthened with a concrete layer on its tensile or compressive side. A numerical example, based on this procedure, is appended
