“…The maximum shear stress s bM is obtained by plugging F, which has been obtained from the above-described structural analysis, into a bond-slip model, which can be borrowed from literature, where there is a rich supply of papers on the bond behavior [1,4,6,7,9,11,12,[16][17][18][19][20][21]37,38].…”

“…Further, many studies were conducted to predict the shear and bending load capacity of FRP that used to strengthen and repair RC beams (Rahimi and Hutchinson, 2001;Al-Zaid et al, 2012;Camata et al, 2007;Yang et al, 2003;Supaviriyakit et al, 2004;Rabinovich and Frostig, 2000). In addition, using FRP as a NSM for strengthening and rehabilitation were proved to be successful in enhancing the shear capacity of RC deep beams (Zhang et al, 2004;Islam et al, 2005;Maaddawy and Sherif, 2009).…”

Studies on the effect of using externally bonded fiber reinforced polymer (FRP) laminates and near surface mounted (NSM) FRP bars on the shear strengthening of reinforced concrete (RC) beams has been widely conducted by various researchers globally. However, an innovative technique using NSM CFRP as anchor bars on the shear strengthening of RC deep beams has never been conducted. Current experimental work on NSM anchor bars has shown good enhancement in the shear capacity for the RC deep beams. This paper presents results obtained from the analytical model of the RC deep beams shear strengthened by NSM CFRP Anchor bars. The study comprises of developing four analytical models using finite element method software ANSYS Version 14. Results of the analytical model and experimental findings were compared for validation. All deep beams were simply supported and subjected to four point bending test with shear span to depth ratio av/d of 0.864. CFRP NSM bars of 5 mm diameter with 450 mm length and spaced at 100 mm (for beams R1 and R2) and 150 mm (for beams R3 and R4) were anchors into their respective beams. Similar properties from the experimental work were adopted for the analytical model. Results from the analytical model such as crack pattern, failure mode and load displacement profile were observed to have good agreement with the experimental findings. Shear capacity shows proximity between the analytical model and experimental results observed at 15 % for beams R1 and R2, and 7 % for beams R3 and R4.

“…The use of Fiber reinforced polymers (FRP) for strengthening reinforced concrete was utilized in construction with their excellent mechanical properties of its strong plasticity, corrosion resistance, tensile and fatigue level [1][2][3]. This provides an excellent material to take the tensile force to strengthen concrete structures in flexure [4][5][6].…”

A total of six beams have been tested to investigate the influence of FRP sheet on the mechanical behavior of concrete beam with different FRP sheet width. In addition, the failure mode of the concrete beam and FRP reinforced concrete beams were also studied by numerical simulation method named Realistic Failure Process Analysis (RFPA). The results indicate that, the loading capacity is increased and maximum deflection of the concrete beam is also increased with the increasing of the FRP sheet width. Moreover, the interfacial debonding easily propagates along the interfacial concrete layer at a load that is below the estimated maximum strength of the FRP-strengthened structure. The maximum strength of the FRP sheet in the experiment was not achieved due to the adhesive layer between the concrete and FRP sheet was not strong enough compared with the numerical simulation result. It showed that the FRP sheet width was considered to be an important factor influence the failure mode and load capacity. So does the interface between the concrete and FRP plate.
