The contribution towards the nominal shear resistance resulting from EB-FRP is provided by the following formula: VRFRP = A FRP h FRP . f f wd (cot + cot )sin . S FRP (13)Inside the new prediction model, f f wd represents the productive tensile strength in EB-FRP intercepted by the shear crack and is determined by the strengthening configuration as follows. 1. Full-wrap configuration f f wd = f f wd,c = k R at f FRPu kR =R 0.five 50 two – R(14) (15)R 50 mm0.five R 50 mmwhere f f wd,c = FRP tensile strength for full-wrap configuration, at = 0.eight, and R = chamfer radius. 2. U-wrap configuration with anchorage system f f wd = k a f f wd,c . 3. U-wrap configuration f f wd = min f f bwd , f f wd,c . eight. Comparison of Experimental Results with Prediction Models of Codes and Design Recommendations Table 7 presents a comparison among experimental EB-FRP contributions to nominal shear resistance Vexp along with the prediction models Vpred in the AB928 References thought of design guidelines. Note that the information in the specimens, such as geometry, strengthening configuration, material properties, and a few outcomes, have currently been displayed in Tables three and six for the experimental studies carried out by the authors and these from the literature, respectively. Figure 8 examines the accuracy on the prediction models by comparing the FRP contribution as predicted (Vpred ) together with the corresponding experimental value (Vexp ). The diagonal within the figure designates the 0 tolerance line, indicating an ideal prediction (Vpred = Vexp ). The points above the line are overestimated predictions (Vpred Vexp ), i.e., around the non-conservative (unsafe) side, whereas those within the decrease component are around the conservative ((-)-Blebbistatin Autophagy secure) side (Vpred Vexp ).
