Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures (ACI 440.2R-02)

Abstract

This paper reports on the key features of the "Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures" issued by the American Concrete Institute (ACI). Fiber reinforced polymers (FRP) systems have emerged as an alternative to traditional materials and techniques for the strengthening of existing concrete structures to resist higher design loads, correct deterioration-related damage, design or construction error, or increase ductility. Structural elements strengthened with externally bonded FRP systems include beams, slabs, columns, walls, joints/connections, chimneys and smokestacks, vaults, domes, tunnels, silos, pipes, and trusses. Externally bonded FRP systems have also been used to strengthen masonry, timber, steel, and cast-iron structures.
