Steel Reinforced Grout for Strengthening of RC T-section Beams Deficient in Shear
الملخص
numerous causes. Thus, proper strengthening and rehabilitation techniques are required
to restore the strength and extend the service life of the structures. Steel reinforced
grout (SRG) has recently been introduced as an efficient and economical strengthening
solution, however, the study on its application for the strengthening of shear-deficient
RC beams is scarce. Thus, this paper is aimed to investigate the efficacy of SRG for
shear strengthening of RC beams with the focus on SRG/stirrups interaction. Six T-cross
section beams were grouped into three series based on their internal shear reinforcement
ratio and tested under three-point bending. Each series comprised of one reference
and one SRG-strengthened beam. The test results revealed that SRG laminates are an
effective technique to increase the shear capacity of RC beams. Up to 71% increase in
the load-carrying capacity of the strengthened beams was achieved. The increase in the
internal shear reinforcement has shown to reduce the shear-strengthening performance
of SRG.
