Abstract
An anchorage system is the most effective method for preventing or delaying the debonding of fiber-reinforced polymer laminates; however, despite extensive studies, the related design information is still unclear and limits its use. The goal of this research, therefore, is to investigate the parameters that affect the debonding strain of CFRP beams secured with different types of anchors. For this purpose, 34 small-scale beams were tested under four-point loading. Two (2) of them were control beams (no FRP, no anchors), 8 were strengthened with FRP at their tension sides, and the remaining 24 were secured with different types of anchor systems (U-wrap, mechanical, or fan). The parameters examined included the compressive strength of the concrete and the number of longitudinal FRPs. It was concluded that these parameters have a considerable effect on the strength of the beams, as well as on the maximum strain of the FRP. The experimental results were compared to the ACI equation and the previous studies to investigate the efficiency of different types of anchors.
