Experimental Test Benefits Table 3 includes the experimental facts and specimen test results linked with groups 1 and two. It incorporates specimen geometry (d and b), materials ratio (w and s ), strengthening configuration and material properties (wFRP , tFRP , FRP , EFRP , FRPu ), contribution of CFRP (sheet or L-shaped laminate) to shear resistance (VFRP ), total nominal shear resistance (Vn ), normalized nominal shear strength at failure (vn = Vn /bd f c ), plus the loss in shear strength with respect towards the smallest beams (loss in vn ). Note that the width in the cross-section has no influence on the size impact as it has been shown by [28]. Therefore, the width of your specimens is not regarded as inside the discussion of your experimental final results. The failure mode of all tested specimens was in shear, with diagonal tensile fracture of concrete. The crack pattern of specimens devoid of transverse steel showed a single crack, as illustrated in Figure 4a, whereas a number of cracks accompanying the primary central crack characterized the specimens with internal steel stirrups (Figure 4b) irrespective of the CFRP strengthening material (sheet or L-shaped laminate). Table 3 shows a maximum shear obtain because of EB-CFRP sheet inside a specimen without the need of internal steel stirrups (S.S0.2L) of 84 , compared with 13 in a specimen with internal steel stirrups (S.S1.2L). Because these two specimens have been of your same size (small), this outcome reveals a substantial reduce in EB-CFRP shear obtain on account of the presence of steel stirrups. Equivalent results were observed inside a study carried out on strengthened RC beams with EB-CFRP by [7]. In specimens with EB-CFRP L-shaped laminate, the maximum shear obtain was 16 in (M.S1.Str), but this improved.
