he specification describes a technique for applying high strength fiber fabric to strengthen beams (12) and the connection between beams (12) and either supported platforms (10) or supporting vertical columns (14).Fabric made of high strength fibers such as glass, boron, or carbon, is laid over the connection between a beam (12) and a platform (10), or between a beam (12) and a supporting column (14), 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. Divisional filed as 500855 |
