Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
(American Society of Civil Engineers, 2010-03-15)This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ... -
Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment
(American Society of Civil Engineers, 2010-10-30)Concrete-filled fiber reinforced polymer (FRP) tubes (CFFTs) have been introduced as a new system for piles, columns and poles. A simple moment connection based on direct embedment of the CFFT into concrete footings or ... -
Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars
(Canadian Society for Civil Engineering:, 2017-05-31)Current design standards ignore any contribution of glass fiber reinforced polymer (GFRP) bars in concrete in a state of compression. This paper challenged this convention by testing 30 cylinders of 36 MPa concrete to ... -
Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
(CSCE, 2016-08-24)Synthetic fibers, such as glass fibers, in the form of fiber-reinforced polymer (FRP) composites have been extensively used for the repair and strengthening of existing concrete structures in the past three decades. As ... -
Durability of Flax FRPs Exposed to Accelerated Environmental Conditions
(CDCC 2017, 2017-07-19)It is well known that synthetic fiber reinforcements, such as glass fibers, elevate the mechanical properties of polymer materials. Considering the synthetic material’s renewability challenges, natural fibers, such as flax ... -
Effect of Fiber Orientation on Nonlinear Behavior of CFRP Composites
(Sage Publications, 2009-09)Fiber orientation is one of the important parameters that affect strength and ductility of FRP-confined concrete columns. A number of studies have been conducted on various fiber orientations and wrap thicknesses, but have ... -
Experimental Study of Rectangular RC Columns Strengthened with CFRP Composites under Eccentric Loading
(American Society of Civil Engineers, 2010-01-28)This paper presents the results of experimental studies on reinforced concrete columns strengthened with CFRP composites under combination of axial load and bending moment. A total of seven large-scale specimens with ... -
Improved Design-Oriented Confinement Models for FRP-Wrapped Concrete Cylinders based on Statistical Analyses
(Elsevier, 2015-03-15)This paper introduces improved design-oriented confinement models for cylindrical concrete members wrapped with fiber reinforced polymer (FRP) composites based on a rigorous statistical evaluation of a large database. As ... -
Lateral Behaviour of Concrete-Filled FRP Tube Piles
(2017-10-01)Applications of fiber-reinforced polymer (FRP) composite piles are rapidly gaining traction in Canada and around the world. FRP piles offer several advantages compared to traditional piles, the most important of which is ... -
MECHANICAL BEHAVIOUR OF DAMAGED REINFORCED CONCRETE PIPES REPAIRED WITH LAYERED SANDWICH FIBER COMPOSITES
(2021-04-08)Trenchless pipe repair can offer time and cost savings over traditional excavation and replacement of damaged pipes. Conventional repair methods using prefabricated steel liners are not effective due to significant loss ... -
RELIABILITY ANALYSIS OF EXTERNALLY BONDED FRP STRENGTHENED BEAMS CONSIDERING EXISTING CONDITIONS: APPLICATION OF STOCHASTIC FE AND CONDITIONAL PROBABILITY
(2022-08-29)The use of externally bonded (EB) fiber reinforced polymer (FRP) to strengthen existing reinforced concrete flexural members is becoming a more heavily used practice due to the advantages FRP has shown over conventional ... -
Short and Slender Concrete Columns Internally or Externally Reinforced with Longitudinal Fiber-Reinforced Polymer Composites
(2020-07-20)The goal of this thesis was to investigate the behavior of short and slender concrete columns internally and externally reinforced with longitudinal fiber-reinforced polymer (FRP) composites. The study was divided into two ... -
Short Concrete Columns Reinforced with GFRP Rebars under Eccentric Loading
