This is a three-part recorded webinar series from August 15 - 17, 2017.
Externally bonded fiber-reinforced polymer (FRP) systems have been used to strengthen and retrofit existing concrete structures around the world since the mid-1980s. 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 were developed as alternatives to traditional external reinforcing techniques such as steel plate bonding and steel or concrete column jacketing. Guidelines from ACI 440.2R-17, “Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures,” and ACI 440.7R-10, “Guide for the Design and Construction of Externally Bonded Fiber-Reinforced Polymer Systems for Strengthening Unreinforced Masonry Structures,” will be discussed.
Part 1 introduces fiber reinforced polymer (FRP) materials, the many externally bonded FRP strengthening systems, and construction guidelines.
Part 2 covers the design of externally bonded FRP systems for flexural strengthening, shear strengthening, confinement, and other engineering considerations.
Part 3 focuses on FRP systems used to strengthen unreinforced masonry structures.
