Damage Threshold of Near-Cross-Ply Tubes Used in Concrete-Filled FRP Tubes Loaded in Flexure
(ASCE, 2020)Concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) have been studied extensively, but a lingering question remains regarding the vulnerability of the exposed tube to accidental damage or vandalism. In this paper, ... -
Post-Tensioned Concrete Beams Strengthened in Shear Using Fiber-Reinforced Polymer Laminates and Patch Anchors
(ASCE, 2020)Strengthening concrete bridges using fiber-reinforced polymers (FRPs) in flexure, shear, and torsion is limited by the occurrence of premature FRP debonding which often controls the degree of strengthening possible using ... -
Seismic Behavior of Square and Circular Concrete Columns with GFRP Reinforcement
(ASCE, 2020)This paper presents results from tests on seven reinforced concrete square columns under simulated seismic loading and demonstrates their satisfactory behavior even when axial load is high. All seven specimens were confined ... -
Global Energy Balance–Based Debonding Modeling of NSM FRP-Strengthened Concrete Beam
(ASCE, 2020)An important advantage of the near surface mounted (NSM) technique for concrete beam strengthening over the externally bonded reinforcement technique is its higher resistance to debonding failures. Despite the increased ... -
Experimental In-Plane Shear Capacity of Clay Brick Masonry Panels Strengthened with FRCM and FRM Composites
(American Society of Civil Engineers, 2019)Unreinforced masonry (URM) buildings, largely found in Euroasian regions, are particularly vulnerable to in-plane shear failures during seismic events due to the poor shear capacity of masonry walls. In the case of historical ... -
A Recalibration of the Crack Width Bond-Dependent Coefficient for GFRP-Reinforced Concrete
(American Society of Civil Engineers, 2019)Serviceability requirements can often control the design of glass fiber–reinforced polymer (GFRP)-reinforced concrete flexural members due to the lower stiffness of GFRP than of steel. ACI Committee 440 crack control ... -
Compressive Behavior of Brick Masonry Columns Confined with Steel-Reinforced Grout Jackets
(American Society of Civil Engineers, 2019)In this study, a new type of composite comprised of steel cords embedded in a mortar matrix—referred to as steel-reinforced grout (SRG)—is explored for use in the confinement of masonry columns. This paper presents the ... -
Flexural Strengthening of RC Beams with Steel-Reinforced Grout: Experimental and Numerical Investigation
(American Society of Civil Engineers, 2019)This paper presents an investigation, both experimental and analytical, on RC beams that are strengthened in flexure using externally bonded steel-reinforced grout (SRG) composites. An experimental investigation was conducted ... -
Effect of Temperature on Bond Behavior of Externally Bonded FRP Laminates with Mechanical End Anchorage
(American Society of Civil Engineers, 2019)The use of mechanical anchorage systems can delay or prevent premature failure of RC structures with externally bonded fiber-reinforced polymer (EB-FRP) laminates. This work reports the results of an experimental program ... -
A Simple Method for the Determination of the Bond-Slip Model of Artificially Aged Joints
(American Society of Civil Engineers, 2019)The durability of adhesively bonded fiber-reinforced polymers (FRP) and concrete substrates has been the subject of recent studies. The degradation of bonded interfaces conjugated with other factors that affect the interface ... -
Novel Ductile FRP System for Concrete Reinforcement: Concept and Experimental Characterization
(American Society of Civil Engineers, 2019)This paper presents a novel design concept for fiber reinforced polymer (FRP) composites consisting of three-dimensional (3D) printed cores and FRP helical skins as a means of ensuring adequate ductility relative to the ... -
In-Plane Shear Characterization of Composite GFRP-Foam Sandwich Panels
(American Society of Civil Engineers, 2019)Shear walls, diaphragms, and shear web structures are generally subjected to in-plane shear loading. Only a small number of test data regarding the in-plane shear behavior of glass fiber–reinforced polymer (GFRP) sandwich ... -
Performance of Eccentrically Loaded Reinforced-Concrete Masonry Columns Strengthened Using FRP Wraps
(American Society of Civil Engineers, 2019)This paper presents an experimental study that investigates the behavior of reinforced masonry (RM) columns strengthened using carbon fiber-reinforced polymer (CFRP) wraps under eccentric axial loading. Nine half-scale ... -
Influence of Anchor Size on Anchored CFRP Systems
