Anchorage and tension-stiffening effect between near-surface-mounted CFRP rods and concrete

The specimen was designed to study the specific problems of NSM: reduction of contact surface area between filling material and concrete and eccentricity of FRP rods. The rods were 12-mm-diameter carbon-epoxy pultruded FRP. The experimental results indicate that NSM technique gives satisfactory results for both anchoring and reinforced concrete flexural member strengthening.
