Abstract
A technique for applying high strength fiber fabric to strengthen beams and the connection between beams and either supported platforms or supporting vertical columns is disclosed. Fabric made of high strength fibers such as glass, boron, or carbon, is laid over the connection between a beam and a platform, or between a beam and a supporting column, and impregnated with an epoxy resin or other polymer matrix. The fabric may be additionally fastened to the structural member using adhesives, fabric fasteners, or bolts. The invention is particularly well suited for retrofitting bridges, freeway overpasses, parking structures, and the like to prevent failure during an earthquake.
