RISPath-Dependent Stress–Strain Model for FRP-Confined Recycled Brick Aggregate Concrete
Publisher: ASCE
Abstract: Fiber-reinforced polymer (FRP) confinement has shown promise as an alternative method aimed at enabling the structural use of recycled brick aggregate concrete (RBAC) in columns. To facilitate practical applications, an ...
Compressive Behavior of FRP–UHPC/ECC–Steel Double-Skin Tubular Columns under Eccentric Loading
Publisher: American Society of Civil Engineers
Abstract: Hybrid double-skin tubular columns (DSTCs), which consist of an outer fiber-reinforced polymer (FRP) tube, an inner steel tube, and a concrete annular layer between the two tubes, possess many advantages, such as high load ...
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 ...
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 Different-Sized FRP-Confined Square Compound Concrete Columns Containing Recycled Concrete Lumps
Publisher: ASCE
Abstract: A new concrete recycling method is to crush demolished concrete into distinctly large recycled concrete lumps (RCLs), which are in a direct mix with fresh concrete, leading to the so-called compound concrete. Not only can ...
Concrete-Filled Multicellular Steel-Tube Shear Walls with FRP Tubes Embedded in CFST: Concept and Seismic Performance
Publisher: ASCE
Abstract: In this study, a new composite shear wall is proposed, which consists of fiber-reinforced polymer (FRP)-confined concrete cores embedded in the concrete-filled steel tubular (CFST) columns as boundary elements of concrete-filled ...
Structural Behavior of RC Foundation Connections for Hybrid FRP-Concrete-Steel Double-Skin Tubular Columns under Constant Axial Compression and Lateral Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: During an earthquake, the casualties and economic loss due to infrastructure failure, such as bridges, are prohibitive. In addition, the deterioration in the steel reinforcements in bridges due to corrosion issues leads ...
Compressive Behavior of Concrete Incorporating Clay Brick Fines Added by Paste Replacement Method
Publisher: ASCE
Abstract: Urbanization in China has been producing a huge quantity of construction and demolition waste, of which clay brick waste accounts for a substantial proportion. For reducing waste disposal, the clay brick waste has been ...
Hybrid FRP–Concrete–Steel Double-Skin Tubular Columns: Creep Behavior and Compressive Behavior after Sustained Loading
Publisher: American Society of Civil Engineers
Abstract: Hybrid fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular columns (DSTCs), which consist of an inner steel and an outer FRP tube, with the space between the two tubes filled with concrete, are a promising ...
Concrete Cover Separation in FRP-Plated RC Beams: Mitigation Using FRP U-Jackets
Publisher: American Society of Civil Engineers
Abstract: Concrete cover separation is a common failure mode of RC beams strengthened with a fiber-reinforced polymer (FRP) plate externally bonded to the tension face (FRP-plated RC beams). This failure mode initiates at the critical ...
