RISLargest Experimental Investigation on Size Effect of Concrete Notched Beams
Publisher: ASCE
Abstract: This work presents an experimental study performed to investigate the effect of the size of the specimen on the fracture response of geometrically similar concrete notched beams. To the best of the authors’ knowledge, this ...
FRP-Masonry Debonding: Numerical and Experimental Study of the Role of Mortar Joints
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymers (FRP) composites are used as supplementary reinforcement to increase the in-plane shear capacity or to provide out-of-plane load-carrying capability of masonry walls and to modify the collapse ...
Size Effect on Shear Strength of Reinforced Concrete: Is CSCT or MCFT a Viable Alternative to Energy-Based Design Code?
Publisher: ASCE
Abstract: After sketching the history of the size effect models for the shear strength of reinforced concrete (RC) in design codes, the energy-based size effect law (SEL), recently incorporated into the American Concrete Institute ...
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 ...
Width Effect in FRP–Concrete Debonding Mechanism: A New Formula
Publisher: ASCE
Abstract: This paper presents the results of an experimental work aimed at determining the effect of the width of a steel fiber-reinforced polymer (FRP) composite on the load-carrying capacity of a composite–concrete interface. ...
Compressive Behavior of Brick Masonry Columns Confined with Steel-Reinforced Grout Jackets
Publisher: American Society of Civil Engineers
Abstract: In this study, a new type of composite comprised of steel cords embedded in a mortar matrix—referred to as steel-reinforced grout (SRG)—is explored for use in the confinement of masonry columns. This paper presents the ...
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 ...
Simulation of Bond Behavior of FRP–Concrete Joints Using the Lattice Discrete Particle Model
Publisher: American Society of Civil Engineers
Abstract: The premature debonding phenomenon of fiber-reinforced polymer (FRP) composites, when externally applied to an RC structure, prevents this technology from fully exploiting its ability of increasing the strength of the ...
