Title: Recent Revisions to Acceptance Criteria for Concrete and Masonry Strengthening Using Externally Bonded FRP Systems (AC125)

Abstract:Although the International Building Code (IBC) refers to the American Concrete Institute - ACI 318 Building Code for reinforced concrete design and to the Masonry Standards Joint Committee Building Code for Masonry Structures (TMS 402/ACI 530/ASCE 5) for masonry building design, neither ACI 318 nor TMS 402/ACI 530/ASCE 5 contain provisions for externally bonded FRP applications. To address this limitation, the International Code Council – Evaluation Services (ICC-ES) published in 1997 the acceptance criteria (AC125) to provide minimum requirements for externally bonded FRP strengthening systems, while meeting the main objectives of the building code, including strength, serviceability, fire safety, and durability. This paper provides the background for the latest revisions to the design criteria section of AC125 to reflect recent FRP knowledge regarding strength and serviceability requirements. These changes align AC125 with ACI 440.2R-08 and ACI 440.7R-10 guidelines, which would provide consistency in evaluation and design requirements of externally bonded FRP composites.
