Experimental Test Final results Table three consists of the experimental information and specimen test final results associated with groups 1 and two. It involves specimen geometry (d and b), supplies ratio (w and s ), strengthening configuration and material properties (wFRP , tFRP , FRP , EFRP , FRPu ), contribution of CFRP (sheet or KL1333 Epigenetic Reader Domain 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 on the cross-section has no Nourseothricin site influence around the size effect since it has been shown by [28]. Thus, the width in the specimens isn’t viewed as in the discussion in the experimental final results. The failure mode of all tested specimens was in shear, with diagonal tensile fracture of concrete. The crack pattern of specimens with out transverse steel showed a single crack, as illustrated in Figure 4a, whereas various cracks accompanying the primary central crack characterized the specimens with internal steel stirrups (Figure 4b) no matter the CFRP strengthening material (sheet or L-shaped laminate). Table three shows a maximum shear achieve resulting from EB-CFRP sheet inside a specimen without the need of internal steel stirrups (S.S0.2L) of 84 , compared with 13 within a specimen with internal steel stirrups (S.S1.2L). Simply because these two specimens have been from the exact same size (little), this result reveals a considerable lower in EB-CFRP shear acquire because of the presence of steel stirrups. Comparable final results had been observed in 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 enhanced.
