Abstract
Flexural Performance of RC Beams Strengthened by Carbon Fiber Reinforced Polymer (CFRP) Laminates
Highlights
The degradation of infrastructure in and around the world requires urgent attention in the form of replacement, rehabilitation or repair
There were two main failure modes for the beams strengthened, i.e. snapping and debonding of CFRP sheets, and shear cracks propagated toward the loading point accompanied by debonding of the CFRP sheets from the concrete
Beams B3: The preloaded concrete beams B3 strengthened with one layer of CFRP fabric, failed due to yielding of steel followed by rupture of fabric and crushing of concrete at mid-span
Summary
The degradation of infrastructure in and around the world requires urgent attention in the form of replacement, rehabilitation or repair. Bonded FRP laminates and fabrics can be used to increase the capacity of corroded beams as well as its shear and flexural strength (Ashour et al 2004). These FRP laminates which are manufactured as sheets or strips by pultrusion are typically made of unidirectional or bidirectional carbon or glass fiber epoxy bonded to concrete structures. While many studies have addressed external strengthening of undamaged concrete members with having various spacing of the wrappings, design considerations such as member cross-section, stirrup and reinforcement ratio, and level of strengthening , little or no information exist on repair of previously damaged members.
