Repair and strengthening of reinforced concrete structures using CFRPs

Abstract

CFRPs offer a high strength lightweight alternative strengthening strategy to traditional methods using concrete overlays and/or steel plates in bridge engineering applications. In addition, the use of CFRPs may offer a viable retrofit/repair strategy in the case of damaged structures, where this damage may be significant. This paper reports on the performance of CFRP-based strategies for the repair and strengthening of two 40% scale continuous flat slab bridge models with significant damage arising from prior static testing to incipient collapse conditions. In addition, the performance after repair using a CFRP scheme of a RC beam-slab-column subassembly, following severe high-load cyclic t..
