ABSTRACT
Fibre Reinforced Polymer (FRP) anchors have been shown to be effective for delaying or even preventing premature debonding failure in concrete structures strengthened with externally bonded FRP. The application of the FRP anchors can improve the loading capability and ductility of the strengthened structure, thus enhancing its seismic resistance. Masonry structures are very common worldwide, but little research has been conducted on the performance of FRP anchors embedded in masonry structures. This study focuses on the behaviour of FRP anchors embedded in clay bricks. One of the differences between brick units and common concrete prism specimens is that the former usually has smaller dimensions. This paper reports an experimental study on FRP anchors under pull-off loading. The experimental results indicate that FRP anchors made from folded pre-wet fibre sheet can efficiently improve the anchorage performance. The size of the anchor hole has significant influences on the performance of anchorage.
