RISGeneral Analytical Model for the Bond Capacity of NSM FRP-Concrete Joints
Publisher: ASCE
Abstract: Fiber-reinforced polymer (FRP) near-surface mounted (NSM) reinforcement represents an effective solution for strengthening and retrofitting existing concrete structures. As it is embedded into concrete, NSM reinforcement ...
Characterization and Design of Multilayer PBO FRCM Composite Reinforcements for Concrete Structures
Publisher: ASCE
Abstract: Fiber-reinforced cementitious matrix (FRCM) composites can be preferred to other techniques to strengthen reinforced concrete (RC) members. Due to the limited cross-sectional area of textiles in FRCM, multilayer composites ...
Role of the Matrix Layers in the Stress-Transfer Mechanism of FRCM Composites Bonded to a Concrete Substrate
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced cementitious matrix (FRCM) composites represent a newly developed promising technique for strengthening RC structures. The FRCM composites are comprised of high-strength fibers applied to the concrete ...
Advances in Knowledge of the Fracture Properties of Cohesive Materials: Fired-Clay and Tuff Bricks
Publisher: ASCE
Abstract: This paper presents an experimental work aimed at determining the fracture properties of fired-clay and tuff brick, obtained from construction sites of existing buildings and a commercially available fired-clay brick. This ...
Tensile Testing of FRCM Coupons for Material Characterization: Discussion of Critical Aspects
Publisher: ASCE
Abstract: Tensile tests on fabric-reinforced cementitious matrix (FRCM) coupons are used to evaluate the tensile mechanical properties of the composite. Bond tests, typically single-lap shear tests, are used to characterize the ...
Three-Dimensional Numerical Modeling of Single-Lap Direct Shear Tests of FRCM-Concrete Joints Using a Cohesive Damaged Contact Approach
Publisher: American Society of Civil Engineers
Abstract: The bond behavior of fiber-reinforced cementitious matrix (FRCM) composites applied as externally bonded reinforcement is the most critical concern in this type of application. FRCM–concrete joints are generally reported ...
Shear Strength Model for RC Beams with U-Wrapped FRCM Composites
Publisher: ASCE
Abstract: The shear strength of reinforced concrete (RC) elements can be improved by applying externally bonded (EB) fiber-reinforced cementitious matrix (FRCM) composites. FRCM composites are generally U-wrapped around the cross-section ...
Shear Strengthening of RC Beams with U-Wrapped FRCM Composites: State of the Art and Assessment of Available Analytical Models
Publisher: American Society of Civil Engineers
Abstract: Shear strengthening of existing reinforced concrete (RC) members with externally bonded (EB) fabric-reinforced cementitious matrix (FRCM) composites represents an attractive solution with respect to alternative strengthening ...
FRP Strips Externally Bonded to Quasi-Brittle Substrates: Discussions and Advances of Open Research Topics
Publisher: American Society of Civil Engineers
Abstract: In the first part of the paper, a critical review of the fundamental knowledge of the debonding mechanism of externally bonded fiber-reinforced polymer (FRP) composites from a quasi-brittle substrate (such as concrete and ...
Shear Strength Model for Reinforced Concrete Beams with U-Wrapped FRCM Composites Based on the Critical Shear Crack Width Evolution
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new procedure to determine the different shear strength contributions of RC beams strengthened with U-wrapped externally bonded (EB) fiber-reinforced cementitious matrix (FRCM) composites. A main shear ...
