Fibre-reinforced polymers in reinforced and prestressed concrete applications: moving forward
(John Wiley & Sons, Ltd.Progress in Structural Engineering and Materials, 2001)
Recent developments in the use of fibre-reinforced polymers (FRPs) in reinforced and prestressed concrete applications are reviewed. The influence of FRP material properties on the design of concrete structures is considered ...
Analysis of concrete beams with partially bonded composite reinforcement
(American Concrete InstituteACI Structural Journal, 2000)
Beams prestressed with partially bonded fiber-reinforced plastic (FRP) tendons have high strength and rotation capacity but cannot be modeled by conventional techniques. Herein, it is assumed that all deformation takes ...
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 ...
Modelling of an unbonded CFRP strap shear retrofitting system for RC beams
(American Society of Civil EngineersASCE Journal of Composites for Construction, 2009)
A retrofitting technique has been developed that uses carbon fiber-reinforced polymer (CFRP) straps to increase the shear capacity of reinforced concrete beams. The vertical straps are not bonded to the beam but are instead ...
Transfer bond stresses generated between FRP tendons and concrete
(Institute of Civil EngineersMagazine of Concrete Research, 1999)
There is a growing interest in the use of new materials in construction. Materials such as fibre-reinforced plastics (FRPs) are lightweight, strong, and, for the most part, non-corrodible. Hence, the use of FRPs as ...
Behaviour of GFRP adhesive pipe joints subjected to pressure and axial loadings
(ElsevierComposites Part A: Applied Science and Manufacturing, 2006)
The corrosion resistance of glass-fibre reinforced polymers (GFRPs) is a key advantage in pipeline applications. Adhesive bonded joints are often used in tensile resistant GFRP pipe systems and the behaviour of small-diameter ...
Nonlinear FE analysis of cracks in tension and shear
(Institute of Civil EngineersMagazine of Concrete Research, 2007-05-01)
Smeared-crack finite element (FE) analyses of reinforced-concrete beams strengthened with prestressed carbonfibre-reinforced polymer (CFRP) shear straps have shown that, at high load levels, the stresses in the straps ...
