“…Most FRP shear reinforcement for concrete members has been studied as a means of retrofitting. Hawileh et al [6] and Al-Tamimi et al [7] suggested techniques that involved externally bonding carbon fiber reinforced polymer (CFRP) laminates or sheets to reinforced concrete members. Hassan and Rizkalla [8] researched the bonding strength of FRP plates that were either embedded or attached to the exterior of concrete members.…”

This paper presents the shear capacities of concrete beams reinforced with glass fiber reinforced polymer (GFRP) plates as shear reinforcement. To examine the shear performance, we manufactured and tested a total of eight specimens. Test variables included the GFRP strip-width-to-spacing ratio and type of opening array. The specimen with a GFRP plate with a3×2opening array showed the highest shear strength. From the test results, the shear strength increased as the strip-width-to-strip-spacing ratio increased. Also, we used the experimental results to evaluate whether the shear strength equations of ACI 318-14 and ACI 440.1R can be applied to the design of GFRP shear reinforcement. In the results, the ACI 440 equation underestimated the experimental results more than that of ACI 318.

“…Many experimental programs and numerical studies investigated different strengthening techniques in which multiple arrangements of FRP plates and sheets were used [10][11][12][13][14][15][16][17][18][19]. Among them, Akbarzadeh and Maghsoudi [10] experimentally investigated the performance of continuous high-strength reinforced concrete beams externally strengthened with CFRP and GFRP sheets.…”

“…However, experimental data have shown that CFRP length has no significant effect on structural behavior when the length of the CFRP is more than 60% of the span length of the beams [7,8]. Al-Tamimi et al [9] investigate flexural behaviors of RC beams strengthened with CFRP plates having different ratio of CFRP plate length to shear span and end anchorage system. In their paper, the beams with reduced amount of CFRP plate length and end anchorage show similar performance to the beam with http://dx.doi.org/10.1016/j.conbuildmat.2015.05.007 0950-0618/Ó 2015 Elsevier Ltd.
