RISBehavior of Concrete Columns Confined by Fiber Composites
Publisher: American Society of Civil Engineers
Abstract: External confinement of concrete by means of high-strength fiber composites can significantly enhance its strength and ductility as well as result in large energy absorption capacity. The confinement mechanism may include ...
Behavior of Ultrahigh-Performance Concrete Confined by Fiber-Reinforced Polymers
Publisher: American Society of Civil Engineers
Abstract: Over a decade of studies have demonstrated the benefits of ultra high performance concrete (UHPC) in terms of damage tolerance, energy absorption, crack distribution, and deformation capacity. However, little information ...
Stress-Strain Model of Ultrahigh Performance Concrete Confined by Fiber-Reinforced Polymers
Publisher: American Society of Civil Engineers
Abstract: The application of ultrahigh performance concrete (UHPC) as an alternative to conventional concrete has grown rapidly in recent years. However, to date, little is known about the confinement behavior of UHPC, knowledge ...
Control of Plastic Shrinkage Cracking of Concrete with Carbon Fiber-Reinforced Polymer Grids
Publisher: American Society of Civil Engineers
Abstract: Five different configurations of carbon fiber-reinforced polymer (FRP) grids were tested for the control of plastic shrinkage cracking of concrete using carbon FRP rods with two different spacings, two configurations of ...
Closure to “Behavior of Concrete Columns Confined by Fiber Composites” by Amir Mirmiran and Mohsen Shahawy

Experimental Investigation of Cyclic Behavior of Concrete-Filled Fiber Reinforced Polymer Tubes
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled fiber reinforced polymer (FRP) tubes (CFFT) have in the last decade been used as girders, beam columns, and piles. The focus of research, however, has been exclusively on their monotonic behavior, with ...
Flexural Creep Tests and Modeling of Concrete-Filled Fiber Reinforced Polymer Tubes
Publisher: American Society of Civil Engineers
Abstract: An experimental and analytical investigation was made into the flexural creep behavior of concrete-filled fiber reinforced polymer (FRP) tubes (CFFT). While creep effects reduce the flexural stiffness of CFFT specimens, ...
Cyclic Behavior of Hybrid Columns Made of Ultra High Performance Concrete and Fiber Reinforced Polymers
Publisher: American Society of Civil Engineers
Abstract: The unique features of ultra-high-performance concrete (UHPC) in damage tolerance, energy absorption, and deformability were combined with the superior performance of concrete-filled fiber-reinforced polymer (FRP) tubes ...
Creep Analysis of Axially Loaded Fiber Reinforced Polymer-Confined Concrete Columns
Publisher: American Society of Civil Engineers
Abstract: An analytical model is developed to study the time-dependent behavior of concrete-filled fiber reinforced polymer (FRP) tubes (CFFT) and fiber-wrapped concrete columns (FWCC) under sustained axial loads. The model utilizes ...
Damage Assessment of FRP-Encased Concrete Using Ultrasonic Pulse Velocity
Publisher: American Society of Civil Engineers
Abstract: Since concrete members with fiber-reinforced polymer (FRP) reinforcement are not as ductile as conventional structures, and since concrete in retrofitted members is often covered and not readily available for visual ...
