RISThermal Compatibility and Bond Strength of FRP Reinforcement in Prestressed Concrete Applications
Publisher: American Society of Civil Engineers
Abstract: Due to concerns with corrosion, the use of fiber-reinforced polymer (FRP) as a replacement to conventional steel reinforcement has greatly increased over the last decade. However, when considering thermal gradients, many ...
Behavior of Split Timber Stringers Reinforced with External GFRP Sheets
Publisher: American Society of Civil Engineers
Abstract: A large number of timber bridges are at the end of their service life in North America and the prohibitive costs of replacement make owners face the challenge of developing efficient rehabilitation techniques. This paper ...
New Approach for Estimating the Deflection of Beams Reinforced with FRP Reinforcement
Publisher: American Society of Civil Engineers
Abstract: Due to concerns with corrosion, the use of fiber-reinforced polymer (FRP) as a replacement to conventional steel reinforcement has greatly increased over the last decade. Researchers have identified the distinctive mechanical ...
Shear Behavior of CFRP Prestressed Concrete T-Beams
Publisher: American Society of Civil Engineers
Abstract: This paper contributes to the scarce research available regarding the shear behavior of carbon fiber–reinforced polymer (CFRP) prestressed concrete beams. The beams were subjected to four-point bending and tested with ...
Flexural Stiffness and Strength of GFRP-Reinforced Timber Beams
Publisher: American Society of Civil Engineers
Abstract: An experimental program was conducted at the University of Manitoba to test salvaged timber stringers strengthened with glass fiber-reinforced polymer (GFRP) laminates. A total of 20 creosote-treated Douglas Fir beams with ...
Bond Characterization and Interfacial Coefficients at Precast UHPC and Cast-in-Place UHPC Interface
Publisher: ASCE
Abstract: Ultrahigh performance concrete (UHPC) is an advanced composite material that exhibits superior compressive and tensile strengths as well as negligible permeability. Although the mechanical properties of UHPC are extensively ...
Flexural Strength of Posttensioned Timber Beams
Publisher: American Society of Civil Engineers
Abstract: An experimental program was conducted at the University of Manitoba to test salvaged timber stringers posttensioned with external carbon fiber–reinforced polymer (CFRP) bars or steel guy cables. A total of 22 creosote-treated ...
Critical Review of Deflection Formulas for FRP-RC Members
Publisher: American Society of Civil Engineers
Abstract: The design of fiber-reinforced polymer reinforced concrete (FRP-RC) is typically governed by serviceability limit state requirements rather than ultimate limit state requirements as conventional reinforced concrete is. ...
Timber Beams Strengthened with GFRP Bars: Development and Applications
Publisher: American Society of Civil Engineers
Abstract: Repair and rehabilitation of infrastructure is becoming increasingly important for bridges due to material deterioration and limited capacity to accommodate current load levels. An experimental program was undertaken to ...
Effect of Cyclic Temperature and Fatigue Load on the Performance of Bond Strength at High-Strength Concrete–UHPC Interface
Publisher: American Society of Civil Engineers
Abstract: One of the most important components of box beam bridges is the shear key that connects the box beams together. The shear keys in box beam bridges often fail at the interface. In recent years, ultrahigh-performance concrete ...
