SHEAR STRENGTHENING REINFORCED CONCRETE BEAMS WITH FIBER-REINFORCED POLYMER: ASSESSMENT OF INFLUENCING PARAMETERS AND REQUIRED RESEARCH

This paper focuses on shear strengthening of reinforced concrete (RC) beams with externally bonded fiber-reinforced polymer (FRP) composites. Its aims are to synthesize findings of the research studies conducted to date, and to examine and analyze the parameters that have the greatest influence on the shear behavior of RC members strengthened with externally bonded FRP. Over 100 tests were considered in the synthesis. Several conclusions were drawn from this work and are discussed. It was found that the parameters related to the properties of the FRP and to those of the shear steel reinforcement are not the only ones having an influence on the shear behavior of RC members strengthened with externally bonded FRP. The shear span ratio a/d, longitudinal steel reinforcement ratio, and geometry of the member also have influence on the shear behavior of these members and deserve further investigation. An experimental parametric study with close variable control is recommended.
