Behavior of Slender GFRP Reinforced Concrete Columns
This paper presents an experimental and analytical study on slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars. The experimental program included ten concrete columns with rectangular ... -
Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
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 ... -
Calibration of Reduction Factor for Concrete Columns Strengthened with Unidirectional Fiber-Reinforced Wrapping
Strengthening with fiber-reinforced polymer (FRP) wrapping is a well-established method of retorifiting or upgrading existing concrete columns. The available test data cooreponding to FRP wrapped concrete columns has ... -
Characterization of Combined Longitudinal and Transverse FRPs for Strengthening Concrete Columns
This paper presents the results of a study on the characterization of combined longitudinal near-surface-mounted (NSM) fiber-reinforced polymer (FRP) bars and transverse FRP wraps for strengthening concrete columns. A total ... -
Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment
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
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 ... -
Contribution of Longitudinal GFRP Bars in Concrete Cylinders under Axial Compression
Contribution of longitudinal glass fiber-reinforced polymer (GFRP) bars in concrete columns under compression has been ignored by current design guidelines. This paper challenges this convention by testing 21 concrete ... -
Cumulative Impact Energy Absorption of Sandwich Panels with Foam Cores and Flax FRP Facings
In this paper, the cumulative energy absorption of sandwich panels constructed of foam cores and flax fiber-reinforced bio-based polymer (FFRP) faces is studied. Nine sandwich panels were constructed and tested under varying ... -
Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
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
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
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 ... -
Effects of long shredded rubber particles recycled from waste tires on mechanical properties of concrete
The goal of this research is to study the mechanical properties of recycled rubber particles extracted from scrap tires in concrete to introduce a sustainable waste management system and subsequently to reduce the use of ... -
Enhancing the Interface Friction between Glass Fiber-Reinforced Polymer Sheets and Sandy Soils through Sand Coating
Soil-pile interface friction is an important geotechnical engineering factor to be considered in achieving a safe, cost-effective design. Conventional construction materials such as concrete, steel, and wood exhibit serious ... -
