Abstract

This paper presents an experimental study on the influence of fiber-reinforced polymer (FRP) anchor configuration on the behavior of FRP plates externally bonded on concrete members. Single shear pull-off tests were conducted on 33 test specimens that were designed with different carbon FRP anchor configurations. The effects of embedment depth, and number and configuration of FRP anchors were examined. Results indicate that all of the investigated parameters influence the peak load capacities of carbon FRP plate, with particularly significant influences on the second peak load capacity. Load-slip behaviors of FRP plates are significantly influenced by the number and configuration of anchors. Distribution and magnitude of the longitudinal FRP plate strains recorded at the initial and second peak load capacities of anchored plates are affected by the anchor configuration. FRP plates with a longitudinal anchor configuration develop higher maximum strains than those of plates with a transverse anchor configuration.
