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 ...
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 ...
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) ...
Effects of solution exposure on the combined axial-shear behaviour of unidirectional CFRP rods
(ElsevierComposites Part A: Applied Science and Manufacturing, 2012-04-06)
In fibre reinforced polymer (FRP) prestressed concrete applications, an FRP tendon must sustain high axial tensile stresses and, if cracks occur, additional dowel forces. The tendon may also be exposed to solutions and so ...
Phased Nonlinear Finite-Element Analysis of Precracked RC T-Beams Repaired in Shear with CFRP Sheets
(American Society of Civil EngineersJournal of Composites for Construction, 2012-10-17)
Phased nonlinear finite-element (FE) analyses were carried out to predict the behavior of precracked reinforced concrete (RC) T-beams repaired in shear with externally bonded (EB) carbon fiber–reinforced polymer (CFRP) ...
Rectangular Reinforced Concrete Beams Strengthened with CFRP Straps
(American Society of Civil EngineersJournal of Composites for Construction, 2013-07-13)
Shear deficient reinforced concrete (RC) structures can be effectively strengthened using external prestressed carbon fibre reinforced polymer (CFRP) straps. Due to the presence of the external elastic straps, a strengthened ...
