Abstract: A method of anchoring surface mounted strengthening systems to a structural member being repaired/strengthened or connecting the surface mounted strengthening systems to adjacent structural members to provide force-transfer or terminating a surface-mounted strengthening system includes drilling a hole in an existing structural member and inserting a portion of a fiber-reinforced anchor or connector into the hole in the existing structural member. The anchor or connector includes a bundle of fibers/rovings, and the portion includes rovings encapsulated in a pre-cured adhesive to form a reinforced portion having a desired cross-sectional size and shape to be received by the hole. The method further includes splaying free ends of the fibers/rovings at an end of the anchor and adhering the splayed ends of the fibers/rovings onto the surface-mounted strengthening system of the strengthened member or onto adjacent members with adhesive.
