External strengthening of RC beams using Gigantochloa Levis (Buluh Beting) fiber reinforced composite plate

Synthetic fiber reinforced polymer (FRP) composite is an efficient method for strengthening of reinforced concrete (RC) externally. Unfortunately, the non-renewable, high cost production and environmental harmful of synthetic fibers had increased public awareness towards this issue and hence inevita...

In terms of structural behavior, it was found that the un-strengthened beam without the shear link in the flexure zone (UNST) has shown a reduction in ultimate load of about 6.72% as compared to the control beam (CB).
