Non-laminated FRP Strap Elements for Reinforced Concrete, Timber and Masonry Applications
(American Society of Civil EngineersJournal of Composites for Construction, 2010-05-11)
Advances in material technology allow for the exploration of new structural forms and systems. In recent years, fiber-reinforced polymers (FRPs) have emerged as candidate materials for civil engineering applications, and ...
External prestressed carbon fiber-reinforced polymer straps for shear enhancement of concrete
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2002)
The use of fiber-reinforced polymers (FRPs) for the strengthening and repair of existing concrete structures is a field with tremendous potential. The materials are very durable and, hence, ideally suited for use as external ...
Time-Dependent Behavior of RC Beams Retrofitted with CFRP Straps
(American Society of Civil EngineersJournal of Composites in Construction, 2010-07-16)
A retrofitting technique that uses prestressed unbonded carbon-fiber-reinforced polymer (CFRP) straps to provide additional shear capacity has previously been shown to be successful under short-term static loading conditions. ...
Water, salt water and alkaline solution uptake in epoxy thin films
(WileyJournal of Applied Polymer Science, 2013-05-10)
As a means of characterizing the diffusion parameters of fiber reinforced polymer (FRP) composites within a relatively short time frame, the potential use of short term tests on epoxy films to predict the long-term behavior ...
Uptake induced swelling and thermal expansion of CFRP tendons
(Institute of Civil EngineersProceedings of ICE, Structures and Buildings, 2009)
Carbon-fibre-reinforced polymer (CFRP) tendons can be used as a corrosion-resistant alternative to steel for reinforcing or prestressing concrete in aggressive marine environments. The design lives of many civil marine ...
Efficient CFRP strap configurations for the shear strengthening of RC T-beams
(American Society of Civil EngineersASCE Journal of Composites for Construction, 2009)
A prestressed carbon fiber-reinforced polymer (CFRP) strap retrofitting system has been found to significantly enhance the shear capacity of existing reinforced concrete beams. In previous studies, the CFRP straps were ...
Experimental behavior of reinforced concrete beams strengthened with prestressed CFRP shear straps
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2007)
One promising means of increasing the capacity of existing shear-deficient beams is to strengthen the structure using external prestressed carbon fiber reinforced polymer (CFRP) straps. In this system, layers of CFRP tape ...
Flexural Fatigue Performance of CFRP Prestressed Concrete Poles
(Multi-Science PublishingAdvances in Structural Engineering, 2012-04-24)
Carbon fibre reinforced polymer (CFRP) prestressed concrete poles offer a durable, light-weight alternative to conventional steel-reinforced or prestressed concrete poles. In particular, the corrosion resistance of the ...
Precracked RC T-beams Repaired in Shear with Prestressed CFRP Straps
(American Concrete InstituteACI Structural Journal, 2013-09-01)
The results of an experimental and numerical investigation involving unstrengthened reinforced concrete (RC) T-beams and precracked RC T-beams strengthened in shear with prestressed carbon fiber-reinforced polymer (CFRP) ...
