Two reinforcement methods and their behavior when applied to reinforced concrete girders in buildings

Abstract

The present paper deals with the flexural strength of girders reinforced by two different methods, as the following part of the research work on the bearing behavior of reinforced concrete structural elements. The first method uses the reinforced concrete to strengthen the girder under the floor construction, in both sides and at the bottom. The second consists in attaching two thin sheets to the sides of the girder, also under the floor construction. Both methods have been proven efficient, and the paper follows with a description of the beams and reinforcements tested, their behaviour and their failure mode and information is given on the different testing stages together with some of the conclusions.
