RISModeling Debonding Failure in FRP Flexurally Strengthened RC Members Using a Local Deformation Model
Publisher: American Society of Civil Engineers
Abstract: Reinforced concrete (RC) beams and slabs can be strengthened by bonding fiber-reinforced polymer (FRP) composites to their tension face. The performance of such flexurally strengthened members can be compromised by debonding ...
Pullout Strength Models for FRP Anchors in Uncracked Concrete
Publisher: American Society of Civil Engineers
Abstract: Mechanical anchorage can delay or even prevent premature debonding failure in externally bonded fiber-reinforced polymer (FRP) composite strengthening systems. A promising type of anchor made from FRP, which is known as a ...

Seismic Performance of Large-Scale RC Eccentric Corner Beam-Column-Slab Joints Strengthened with CFRP Systems
Publisher: ASCE
Abstract: Eccentric corner beam-column joints of existing reinforced concrete (RC) frames, in which the beam axes are eccentric to the column axis, can be highly vulnerable to brittle joint shear failure under earthquake loading. ...
Durability and Long-Term Performance of FRP-to-Concrete Joints under Environmental Conditioning: Experimental and Analytical Study
Publisher: ASCE
Abstract: The external bonding of fiber-reinforced polymer (FRP) composite plates and sheets to the tensile surface of reinforced concrete structural elements is a viable retrofitting technique. The performance of such strengthened ...
Experimental Study on the Confinement of Concrete Cylinders with Large Rupture-Strain FRP Composites
Publisher: ASCE
Abstract: Large rupture strain (LRS) fiber-reinforced polymer (FRP) composites, typically formed from polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fibers, generally exhibit ultimate rupture strains >5%. ...
FE Modeling of CFRP-Repaired RC Beams Subjected to Fatigue Loading
Publisher: American Society of Civil Engineers
Abstract: A constitutive model is developed for fiber-reinforced polymer (FRP)-to-concrete bond for fatigue loading. The model is verified against available test data with a framework developed for further calibration as new data ...
Behavior and Effectiveness of FRP Wrap in the Confinement of Large Concrete Cylinders
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental investigation on the strength and behavior of large 250 mm diameter concentrically loaded unreinforced fiber-reinforced polymer (FRP) confined concrete cylinders. In this ...
FE Modeling of FRP-Repaired Planar Concrete Elements Subjected to Monotonic and Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: In this paper, a nonlinear finite-element model is developed for the analysis of plane stress members, such as RC beams and walls, strengthened either unidirectionally or bidirectionally with fiber-reinforced polymer (FRP) ...
Experimental Investigation on FRP-to-Timber Bonded Interfaces
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental study on fiber-reinforced polymer (FRP) to timber bonded interfaces. A series of tests on 86 single shear FRP-to-timber joints is reported, of which the test parameters ...
