Experimental Study on Shear Interaction of Carbon Fibre Reinforced Polymer (CFRP) and Transverse Steel Stirrups on Shear Strengthened RC Beams

Multitudes of research has been done to study the behavior of FRP on the shear
strengthening of RC beams, but yet the guidelines for FRP design are still very
questionable in terms of the design optimization. There is yet a conclusive model that
can accurately represents the actual effect of FRP on the shear contribution to the RC
structure. This program was carefully designed and instrumented to present more data
to the pool of research on this topic by studying different parameters that affects the
FRP shear contribution, particularly on the steel stirrups ratio, FRP ratio and effect of
different wrapping schemes. Hence, ten rectangular beams were assembled with
different internal steel stirrups spacing of 200mm, 150mm and 100mm, further
reinforced with variable width of FRP strips and wrapping scheme of either U-wrap or
side bonded.
