Flexural behaviour of SRG (steel reinforcing grout)-strengthened reinforced concrete beams

This paper presents the results of an experimental investigation of the flexural response of reinforced concrete (RC) beams strengthened with a steel reinforced grout (SRG) system bonded to the tension face with or without the use of mechanical anchors. Test results in terms of failure modes, failure load, load- deflection curves, strain and stress distributions and ductility, presented and discussed in the paper, point out the effectiveness of the SRG composites as strengthening systems of existing reinforced concrete structures.
