This paper describes the technique of increasing beam strength by means of externally applied reinforcing steel plates, bonded by means of epoxy-resin adhesive. Test methods, application data, and some indication of preferred resin formulation are given. Steel plates are bonded to the beams by means of epoxy-resin paste adhesive. During curing of the resin the plates are held in place by clamps and/or bolts. This provides an inexpensive method of restoring or upgrading the strength of damagaed or substrength concrete bridge and similar beams. To date, results have proved entirely satisfactory, but possible dangers of corrosion on the steel-concrete interface are being investigated. Further work is foreseen that will employ new materials and methods of application and enlarge the scope of the process. (Author)
