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 ...
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 ...
CFRP prestressed concrete lighting columns
(American Concrete InstituteField Applications of FRP Reinforcement: Case Studies, 2003)
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 ...
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 ...
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 ...
