RISBond Durability of FRP Bars Embedded in Fiber-Reinforced Concrete
Publisher: American Society of Civil Engineers
Abstract: A research program was initiated to develop a nonferrous reinforcement system for concrete bridge decks using continuous fiber-reinforced polymer (FRP) bars and discrete, randomly distributed polypropylene fibers. This ...
Experimental Assessment of Shear Transfer Capacity of GFRP Reinforcement Using the Push-Off Test
Publisher: American Society of Civil Engineers
Abstract: The interface shear transfer mechanism in concrete structures has been studied for several decades and its investigation has served as the basis for the provisions of current design specifications. However, most of the ...
Effects of Corrosion of Steel Reinforcement on RC Columns Wrapped with FRP Sheets
Publisher: American Society of Civil Engineers
Abstract: This study investigated the effectiveness of carbon fiber-reinforced polymer (CFRP) sheets in protecting reinforced concrete (RC) columns from corrosion of steel reinforcement. Thirty small-scale RC columns and four midscale ...
Model for Reinforced Concrete Members under Torsion, Bending, and Shear. I: Theory
Publisher: American Society of Civil Engineers
Abstract: A model has been developed that can predict the load-deformation response of a reinforced concrete (RC) member subjected to torsion combined with bending and shear to spalling or ultimate capacity. The model can also be ...
Model for Reinforced Concrete Members under Torsion, Bending, and Shear. II: Model Application and Validation
Publisher: American Society of Civil Engineers
Abstract: A model was recently proposed for predicting the load-deformation response of a reinforced concrete member under torsion combined with bending and shear to spalling or ultimate. This paper shows the application of the model ...
Material Laws of FRP-Strengthened RC Element in Biaxial Tension–Compression

Three-Dimensional Nonlinear Finite-Element Analysis of Prestressed Concrete Beams Strengthened in Shear with FRP Composites
Publisher: American Society of Civil Engineers
Abstract: Nonlinear finite-element (FE) analysis was carried out to investigate the structural response of prestressed concrete (PC) beams strengthened with fiber reinforced polymer (FRP) composites in shear. Development of the FE ...
Nonlinear Finite-Element Modeling of Concrete Bridge Girders Prestressed with Carbon Fiber–Reinforced Polymers
Publisher: American Society of Civil Engineers
Abstract: Concrete beams (girders) prestressed with steel cables are widely used in highway bridges. The prestressed steel cables are prone to area loss due to corrosion. The high stress level and deteriorated bond due to corrosion ...
Numerical Simulation of Partial-Depth Precast Concrete Bridge Deck Spalling
Publisher: American Society of Civil Engineers
Abstract: This paper describes the results of numerical simulations performed to investigate the spalling mechanism observed in several partial-depth precast prestressed concrete (PPC) bridge decks. Corrosion-induced cracking of ...
Reliability Assessment of FRP-Strengthened Concrete Bridge Girders in Shear
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results from an investigation into the reliability of reinforced concrete bridge girders strengthened in shear using fiber-reinforced polymers (FRP). Two expressions for the shear design of ...
