Abstract:
Strengthening of concrete structures in situ by bonding steel plates to concrete surfaces through epoxy-resin adhesives is now recognized as an effective and convenient method of improving their performance under service loads and increasing their ultimate strength. This paper presents a critical review of the structural behavior of the plated beams with emphasis on the effects of plating on serviceability and ultimate limit states. Problems of premature bond failure are described, and methods of overcoming such failures and insuring full flexural capacity, ductility, and composite action are reported. Resistance to fire hazards and other relevant design considerations are discussed.
