FRP Confined Reinforced Concrete Circular Cross Section Seismic Applications
… by incorporating an FRP confined concrete stress-strain model into a developed Moment-Curvature and PM Interaction software. This software conducts a comparison between traditional steel and FRP confined sections while performing parameter studies on the 28-day unconfined concrete compressive …

Seismic characterization of recycled aggregate concrete
… of RAC behavior under multiaxial state of stresses. The main objective of this research is the characterization of seismic properties of RAC by developing a stress-strain model which can reasonably describe the behavior under both unconfined and confined conditions. An extensive …

Stress-Strain Behavior for Actively Confined Concrete Using Shape Memory Alloy Wires
… material being able to recover large inelastic strains with the application of heat. Due to the extraordinary behavior that these SMAs display, this confining method is classified as “active confinement”, which has been proven to be superior in almost every way to the ordinary passive …

Effect of concrete heterogeneity on FRP-to-concrete bond behaviour
… of concrete heterogeneity. <br/>A 2D mesoscale modelling framework is proposed, integrating the capabilities of generating mesoscale geometric structures with Matlab programming, incorporating the geometry into ABAQUS with Python scripting, and solving finite element (FE) models with ABAQUS. The …

Performance of confined concrete columns under simulated life cycles
… of confinement and ductility. The development of stress-strain models for FRP confined concrete began with the adaptation of steel confinement models then progressed to models specifically developed based on test results from FRP confined specimens. State of the art stress-strain models for FRP …

Polypropylene fiber reinforced concrete in railway crossties
… is relatively weak and brittle under tensile stresses. Inclusion of synthetic polypropylene macro fibers in concrete is known to improve crack resistance and is a feasible solution for prolonging the life of crossties. The present study investigated the performance of synthetic polypropylene …

Behavior, strength and flexural stiffness of circular concrete columns reinforced with FRP bars and spirals/hoops under eccentric loading
La détérioration des structures en béton armé avec des barres d’armature d’acier peut être observée quotidiennement dans les régions à climat agressif. Le renforcement interne en polymères renforcés de fibres (PRF) a démontré sa faisabilité grâce à différents éléments structuraux en génie civil. …
