ABSTRACT:
An anchorage system for structural reinforcement of surface bonded reinforcing sheet, plate or shell made of fiber reinforced plastic (FRP) or steel or other metallic or non-metallic materials is disclosed. The anchorage system comprises an anchor tube or solid rod with a circular outer surface and a lock-down means provided along the longitudinal axis of the tube or rod. The lock-down means can be either an anchor bolt mounted through the center of the anchor tube or rod or an anchor strap pressed against the circular surface of the tube or rod into the members to be reinforced. The FRP reinforcing sheet, plate or shell is bonded to the surface of the structural member, and optionally, the supporting member, and passes underneath the outer circular surface of the tube or rod. The tube or rod is held securely by the lock-down means which, in turn, compresses and holds in place the FRP sheet against the surface of the structural member.
