The use of fiber-reinforced polymers (FRP) for the repair and seismic retrofit of existing concrete and masonry structures is continually growing. An integral part of the FRP solution is the use of FRP anchors as anchors can delay unwanted premature debonding failure. Anchors can also help to transfer forces from the FRP to adjacent structural elements. FRP anchors comprise two main components, namely (i) a portion embedded into the concrete or masonry member, and (ii) a splay portion that is connected to the FRP strengthening. It is the splay portion of the anchors which is considered in this paper as there has been very little research conducted to date in this area. A series of tests is therefore reported and a design formula is proposed.
