Experimental Test Outcomes Table 3 includes the experimental info and specimen test benefits linked with groups 1 and 2. It consists of specimen geometry (d and b), components ratio (w and s ), strengthening configuration and material properties (wFRP , tFRP , FRP , EFRP , FRPu ), Fenbutatin oxide Parasite 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 for the smallest beams (loss in vn ). Note that the width with the cross-section has no influence on the size effect because it has been shown by [28]. Consequently, the width on the specimens is not regarded inside the discussion from the experimental benefits. The failure mode of all tested specimens was in shear, with diagonal tensile fracture of concrete. The crack pattern of specimens without the need of transverse steel showed a single crack, as illustrated in Figure 4a, whereas various cracks accompanying the main Loracarbef supplier central crack characterized the specimens with internal steel stirrups (Figure 4b) regardless of the CFRP strengthening material (sheet or L-shaped laminate). Table three shows a maximum shear acquire as a result of EB-CFRP sheet inside a specimen without having internal steel stirrups (S.S0.2L) of 84 , compared with 13 within a specimen with internal steel stirrups (S.S1.2L). Because these two specimens were in the identical size (modest), this result reveals a considerable decrease in EB-CFRP shear achieve because of the presence of steel stirrups. Comparable final results have been observed within a study carried out on strengthened RC beams with EB-CFRP by [7]. In specimens with EB-CFRP L-shaped laminate, the maximum shear acquire was 16 in (M.S1.Str), but this increased.
