Shear Strengthening of RC Beams with FRCM: What Do We Know So Far?
Shear failure of reinforced concrete (RC) beams is an undesirable mode of failure due to its sudden and brittle nature and thus needs to be carefully evaluated when planning a strengthening intervention. The use of fiber reinforced polymer (FRP) composites has shown to be capable of providing an adequate increase in shear strength. However, in recent years, there is interest in developing new techniques in which the positive attributes of FRP are utilized but some of its drawbacks are overcome. Among these techniques, fiber reinforced cementitious matrix (FRCM) composites, in which the organic resins are replaced by inorganic mortars, have shown promising results. In this paper, a bibliographical review of the available literature on FRCM shear strengthening of RC beams is carried out. Two available design models are evaluated using a database compiled by the authors. The review shows that FRCM is able to provide an increase in strength and performance comparable to RC beams strengthened with FRP. However, the models are not able to accurately predict the behavior of FRCM strengthened beams.
