RISConcrete Damage Plasticity Model for Modeling FRP-to-Concrete Bond Behavior
Publisher: American Society of Civil Engineers
Abstract: The technique of externally bonding fiber-reinforced polymer (FRP) composites has become very popular worldwide for retrofitting existing reinforced concrete (RC) structures. Debonding of FRP from the concrete substrate ...
Effective Cross Sections of Asymmetric Rings on Cylindrical Shells
Publisher: American Society of Civil Engineers
Abstract: Rings or ringbeams are often used to stiffen cylindrical tanks, silos, towers, and pressure vessels. A ring acts together with the axisymmetric shell to form a composite structure. The structural analysis of such a composite ...
Anchorage Strength Models for FRP and Steel Plates Bonded to Concrete
Publisher: American Society of Civil Engineers
Abstract: External bonding of steel plates has been used to strengthen deficient reinforced-concrete structures since the 1960s. In recent years, fiber-reinforced polymer (FRP) plates have been increasingly used to replace steel ...
Stresses in Inclined Planar Silos
Publisher: American Society of Civil Engineers
Abstract: This paper presents an approximate solution for the stresses in an inclined planar silo. The solution may be applied to the design of inclined rectangular silos with a large aspect ratio and to the design of mining tunnels. ...
Shear Capacity of Fiber-Reinforced Polymer-Strengthened Reinforced Concrete Beams: Fiber Reinforced Polymer Rupture
Publisher: American Society of Civil Engineers
Abstract: A recent innovation in shear strengthening of reinforced concrete beams is to externally bond fiber-reinforced polymer (FRP) composites. Many studies have been undertaken on this strengthening technique. These studies have ...
Factors Affecting the Ultimate Condition of FRP-Wrapped Concrete Columns
Publisher: American Society of Civil Engineers
Abstract: Fiber reinforced polymer (FRP)-wrapped circular concrete columns under axial compression usually fail as a result of FRP rupture in the hoop direction. The average measured hoop strain in the FRP jacket at failure of such ...
Shear Strength Model for FRP-Strengthened RC Beams with Adverse FRP-Steel Interaction
Publisher: American Society of Civil Engineers
Abstract: RC beams shear strengthened with externally bonded fiber-reinforced polymer (FRP) U strips or side strips usually fail owing to debonding of the bonded FRP shear reinforcement. Because such debonding usually occurs in a ...
Effect of Geometric Discontinuities on Strains in FRP-Wrapped Columns
Publisher: American Society of Civil Engineers
Abstract: Extensive research on fiber-reinforced polymer (FRP) confinement strengthening for concrete columns has led to a good understanding of, and accurate models for, circular columns subjected to axial load. This research is ...
Finite-Element Modeling of Intermediate Crack Debonding in FRP-Plated RC Beams
Publisher: American Society of Civil Engineers
Abstract: Intermediate crack-induced debonding (IC debonding) is a common failure mode of RC beams strengthened with externally bonded fiber-reinforced polymer (FRP) reinforcement. Although extensive research has been carried out ...
Behavior of FRP-Confined Circular RC Columns under Eccentric Compression
Publisher: ASCE
Abstract: Strengthening of reinforced concrete (RC) columns through lateral confinement with a fiber-reinforced polymer (FRP) jacket has become an increasingly popular technique over the last two decades. To enable the safe and ...
