North American design guidelines for concrete reinforcement and strengthening using FRP:...

Abstract

This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. For new construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). For repair and upgrade, strengthening of concrete members with externally bonded FRP laminates or near surface mounted (NSM) bars has received remarkable attention. Th
