New mechanics-based confinement model and stress–strain relationship for analysis and design of concrete columns wrapped with FRP composites
The analysis and design of concrete columns wrapped with fiber-reinforced polymer (FRP) composites require the mathematical equation of stress–strain relationship and the ultimate conditions (i.e., stress and strain) ... -
Numerical Modeling of the Lateral Behavior of Concrete-Filled FRP Tube Piles in Sand
In this study, a numerical model is developed to study concrete-filled FRP tube (CFFT) pile behavior and interactions with foundation soil under lateral loading. The model, based on nonlinear finite element analysis (NFEA) ... -
Parametric study of the flexural behaviour of sandwich panels with flax FRP faces and foam cores using finite element analysis
To meet the growing demands for increased sustainability in infrastructure, it is important to consider the use of more environmentally-friendly materials, such as plant-based fibre-reinforced polymers (FRPs). Plant-based ... -
Partial-Composite Behavior of Sandwich Beams Composed of Fiberglass Facesheets and Woven Fabric Core
In this study, thin-walled sandwich composites made of glass fiber-reinforced polymer (GFRP) facesheets and a three-dimensional (3D) woven fabric core were studied. A total of 30 small-scale sandwich beam specimens were ... -
Performance of High-Modulus Near-Surface-Mounted FRP Laminates for Strengthening of Concrete Columns
This study investigates the performance of high-modulus near-surface-mounted (NSM) fiber-reinforced polymer (FRP) laminates in strengthening of existing concrete columns. The focus of this study is on the compressive and ... -
Post-impact residual strength and resilience of sandwich panels with natural fiber composite faces
In this paper, the post-impact residual flexural behavior of sandwich panels with flax fiber-reinforced polymer (FFRP) faces and polyisocyanurate (PIR) foam cores is investigated experimentally. The faces were manufactured ... -
Recycled gypsum powder from waste drywalls combined with fly ash for partial cement replacement in concrete
Recent developments towards sustainable infrastructure have motivated more environmentally conscious construction practices. The concrete industry is known to have a large carbon footprint, which can be decreased by reducing ... -
Reliability-Based Evaluation of the Stiffness Reduction Factor for Slender GFRP Reinforced Concrete Columns
The stiffness of concrete columns is adjusted by a factor referred to as the stiffness reduction factor or the stability resistance factor when utilizing the simplified second-order moment magnification method for designing ... -
Residual Behavior of Sandwich Panels with Flax FRP Faces and Foam Cores after an Impact Event

Second-order Analysis of Slender GFRP Reinforced Concrete Columns Using Artificial Neural Network
Analysis of slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars is required for design and optimization purposes. Finite element, finite difference, and analytical-numerical tools were ... -
Self-Healing Concrete: A Review of Recent Research Developments and Existing Research Gaps
Self-healing materials are defined as the materials that are able to partially or completely restore their original functionality after they have been damaged. In cementitious materials, such as concrete, this concept is ... -
Self-healing of Engineering Cementitious Composite with Crystalline Admixture Under Different Exposure Conditions
Self-healing mechanisms in concrete can promote healing of cracks with the material produced through the concrete itself. Engineered Cementitious Composites (ECC) is a special category of HighPerformance Fiber Reinforced ... -
Shear and Bending Behaviour of Short-span Steel-reinforced Concrete-filled FRP Tubes with ±55◦ Fiber Orientation
In this study, steel-reinforced concrete-filled ±55◦ glass-fiber-reinforced-polymer (GFRP) tubes (CFFT) are examined under monotonic loading to understand their shear behaviour. A total of three test specimens with three ... -
Short Concrete Columns Reinforced with GFRP Rebars under Eccentric Loading
In this paper, the compressive performance of short concrete columns reinforced with glass fiber-reinforced polymer (GFRP) composite rebars is evaluated. A total of fourteen 500 mm long concrete specimens with square ... -
Simplified Material Model for Concrete Containing High-Content of Tire-Derived Coarse Aggregate under Compression Loading
The flexible properties of the shredded rubber tires give rubberized concrete desirable properties such as lower relative density, and better dampening ability, higher toughness, and improved deformability resulting in an ...
