Abstract
A method of reinforcing a structural member comprises positioning a shell around the structural member, placing a force dampening material around an exterior of the shell and securing the force dampening material around the shell. In certain arrangements, the method further includes at least partially filling a space defined between the structural member and the shell with a filler material. In some embodiments, the filler material comprises a concrete, a grout, an epoxy, combinations thereof and/or the like. In one embodiment, the shell comprises a fiber reinforced polymer (e.g., CFRP, GFRP, aramid fibers, epoxy, other resins, etc.). In alternative embodiments, the methods additionally includes placing one or more layers of fiber reinforced polymer around the shell prior to placing a force dampening material around an exterior of the shell. In some embodiments, the layer of fiber reinforced polymer comprises CFRP, GFRP or any other type of fiber reinforced polymer.
