Durability and Failure Modes of Concrete Beams Strengthened with Polyurethane or Epoxy CFRP
(ASCE, 6/1/2021)Externally bonded carbon-fiber-reinforced polymer (CFRP) composites are increasingly being used for repair of concrete infrastructure. Both the mechanical performance and the long-term durability of such a repair have ... -
Punching Shear Behavior of Synthetic Fiber–Reinforced Self-Consolidating Concrete Flat Slabs with GFRP Bars
(ASCE, 8/1/2021)Glass fiber–reinforced polymer (GFRP)-reinforced flat slabs offer a convenient construction option that is both simple to build and highly resistant to corrosion. The relatively low thickness of the floor plates and absence ... -
Prediction of Concrete Cover Separation in Reinforced Concrete Beams Strengthened with FRP
(ASCE, 8/1/2021)Fiber-reinforced polymers (FRPs) are widely used to enhance the flexural capacity of existing concrete structures subjected to various loading actions. However, when FRPs are applied to structural elements as externally ... -
Large-Scale FRP-Confined Rectangular RC Columns with Section Curvilinearization under Axial Compression
(ASCE, 6/1/2021)A novel technique to improve the effectiveness of fiber-reinforced polymer (FRP) confinement for strengthening rectangular reinforced concrete (RC) columns is to implement section curvilinearization (SC) before FRP wrapping. ... -
Shear Behavior of Post-Tensioned Concrete Beams with Draped FRP Tendons and without Transverse Reinforcement
(ASCE, 8/1/2021)To investigate the shear behavior of post-tensioned concrete beams with fiber-reinforced polymer (FRP) reinforcements, six large-scale post-tensioned beams without transverse reinforcement and with a shear span-to-effective ... -
Effect of Elevated Temperatures on the Mechanical Properties and Relaxation of CFRP Strands
(ASCE, 6/1/2021)Although prestressing carbon fiber–reinforced polymer (CFRP) strands outperform steel strands on different levels, such as strength and durability, their performance under elevated temperatures remains a susceptible design ... -
Flexural Strengthening of Two-Way RC Slabs with Cut Openings Using Textile-Reinforced Mortar Composites
(ASCE, 6/1/2021)This paper presents an experimental investigation on the application of textile-reinforced mortar (TRM) layers as a means of increasing the flexural capacity of two-way reinforced concrete (RC) slabs with cut openings. The ... -
One-Way Shear Strength of FRP–Reinforced Concrete Members Without Stirrups: Design Provision Review
(ASCE, 6/1/2021)The American Concrete Institute recently updated their one-way shear provisions for steel–reinforced concrete (RC), and it is time to consider updating provisions for one-way shear in fiber-reinforced polymer (FRP)-reinforced ... -
Development of a Mechanical Wedge–Barrel Anchor for CFRP Rods: Static and Fatigue Behaviors
(ASCE, 6/1/2021)In this study, a mechanical anchorage for prestressed carbon fiber–reinforced polymer (CFRP) rods was proposed. The proposed anchorage consisted of a steel barrel with a conical hole and three separate aluminum wedges that ... -
Shear Behavior of Brick Masonry Walls Strengthened with Textile-Reinforced Concrete
(ASCE, 6/1/2021)In this study, in-plane shear tests were performed on 20 masonry wall specimens. The research factors considered included the length, height, thickness, fiber material, and number of textile-reinforced concrete (TRC) layers ... -
Torsional Behavior of Circular Concrete-Filled FRP Tubes
(ASCE, 6/1/2021)Concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) have been studied extensively under almost all loading conditions, except torsion. In this pioneering study, six 168-mm-diameter samples were tested in pure ... -
