Abstract
Fibre reinforced polymer (FRP) anchors made from rolled or folded fibres have been shown to be an effective technology for delaying or even preventing premature debonding failure in concrete structures strengthened with externally bonded FRP. It would naturally be expected that the use of FRP anchors can improve the earthquakeresistance of FRP strengthened structures by increasing its loading capacity and ductility especially the latter. This study explores the application of FRP anchors in seismic strengthening of clay brick walls. One unique feature of such a system is that the brick unit has smaller dimensions compared to common concrete specimens. This paper reports an experimental pull out study of these FRP anchors. Test parameters included anchor construction, the diameter of the anchor, and the size of predrilled holes in clay brick. The experimental results indicate that FRP anchors can be designed to achieve high loading capacities and hence can be effectively used to prevent or delay FRP debonding failure. The results also indicate that the geometry of the anchor system has a significant effect on its loading capacity.
