To evaluate the shear performance of deep beams reinforced with Glass Fiber Reinforced Polymer (GFRP) plate, a test was conducted on 8 specimens. Test variables included reinforcement, shear span ratio, area of reinforcement, and e ective depth. The e ects of the test parameters on the shear strength of the test specimens were evaluated. The test result showed that smaller span ratio leads to larger shear strength, and that increase in the area of reinforcement and e ective length increased shear strength. All test results were compared with strut-and-tie models suggested by ACI 318 and CSA.
