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 ... -
Condition assessment of reinforced concrete bridge decks as conductive media using GPR
(2014-07-07)Bridge and overpass infrastructure are crucial parts of transportation networks that must be adequately maintained to ensure minimal repair costs and traffic disruption. The majority of the bridges and overpasses in North ... -
DEVELOPMENT OF NONLINEAR FINITE DIFFERENCE MODEL FOR CHLORIDE DIFFUSION IN CONCRETE
(2016-07-06)Owing to problems associated with chloride-induced corrosion, the reliable prediction of chloride ingress into concrete is one of the key elements of the durability design and redesign of concrete structures exposed 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 ... -
EFFECT OF COMBINED SHEAR, BENDING AND LOW AXIAL LOAD ON BEHAVIOR OF CONCRETE BEAMS REINFORCED WITH GLASS FIBER-REINFORCED POLYMER BARS
(2021-04-29)This research's main objective was to investigate the effect of combined bending and shear behavior of the concrete beams reinforced with glass fiber reinforced polymer (GFRP) bars subjected to low axial load less than 10% ... -
Experimental and Analytical Behavior of Short Concrete Columns Reinforced with GFRP Bars under Eccentric Loading
(Elsevier, 2017)This paper presents experimental and analytical studies on short concrete columns reinforced with glass fiber-reinforced polymer (GFRP) towards characterizing compressive behavior GFRP bars. The experimental program consisted ... -
Experimental Evaluation of the Bond Dependent Coefficient and Parameters which Influence Crack Width in GFRP Reinforced Concrete
(2013-04-04)Reinforcement of concrete flexural components has been traditionally provided by steel rebar; however, durability concerns and life maintenance costs of this product have powered the emergence of fibre reinforced polymers ... -
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 ... -
Gypsum powder recycled from waste drywalls as a partial cement replacement in concrete
(2020-04-14)This experimental study was divided into three main phases using recycled gypsum powder in concrete aiming to introduce a more sustainable and ecological alternative to traditional concrete, while maintaining adequate ... -
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 ... -
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 ... -
