Abstract: |
This paper includes an experimental program to study the shear behavior of concrete beams reinforced in shear with fiber glass reinforced polymer GFRP and carbon fiber reinforced polymer CFRP stirrups manufactured onsite. A total of six specimens were tested to study several parameters including the type of FRP material used to manufacture the stirrups, the angle of inclination of the stirrups and the thickness to bend radius ratio (r/t) of the stirrups. The experimental results showed that the ultimate strength of beams reinforced with carbon fiber stirrups is significantly higher than that of beams reinforced with fiber glass stirrups for the same area, for the same area increasing the diameter increases the failure load and strains in the stirrups while decreasing the thickness decreases the failure load and strains in stirrups, due to the reduction of the stress concentration at the corners of the stirrups and that increasing the inclination angle of the stirrups with the horizontal increases the strain in the stirrups and ultimate strength. |
