RISClosed-Form Solution of the Ductility of Short FRP-Wrapped Rectangular Concrete Prisms under Eccentric Loads
Publisher: ASCE
Abstract: Confinement reinforcement, such as tubes, stirrups, and wraps, can significantly improve the strength and, more importantly, ductility of eccentrically loaded concrete prisms. However, the confinement effect in flexural ...
Influence of River Sinuosity on the Distribution of Conservative Pollutants
Publisher: American Society of Civil Engineers
Abstract: The influence of river sinuosity on the distribution characteristics of pollutants in a wide river is investigated three-dimensionally with a numerical model. It is found that, for a meandering river, the hydrodynamic force ...
Real-Time Monitoring of Early-Age Concrete Strength Using Piezoceramic-Based Smart Aggregates
Publisher: American Society of Civil Engineers
Abstract: It is well known that concrete is the most common type of structural material, and a proper estimation of concrete strength in its early age can provide guidance for staged concrete construction and ensure the load-bearing ...
Physicochemical Properties and Formation Mechanism of Soot in the MILD–OCC Combustion Flame
Publisher: ASCE
Abstract: Coal and methane were mixed and burned in the moderate and intensive low oxygen dilution–oxy coal combustion (MILD–OCC) mode, flame temperature was measured at different flame locations with a rapid insert thermocouple, ...
Multiple-Scale Analysis of a Tunable Bi-Stable Piezoelectric Energy Harvester
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the theoretical modeling and multiple-scale analysis of a novel piezoelectric energy harvester composed of a metal cantilever beam, piezoelectric films, and an axial preload spring at the moveable end. ...
Pore Morphology, Porosity, and Pore Size Distribution in Kaolinitic Remolded Clays under Triaxial Loading
Publisher: ASCE
Abstract: This work aims to investigate the micropore properties of saturated kaolin subjected to triaxial loading. Consolidated drained triaxial compression tests were conducted on both normally consolidated and overconsolidated ...
Disintegration Characteristics and Mechanisms of Carbonaceous Mudstone Subjected to Load and Cyclic Drying–Wetting
Publisher: ASCE
Abstract: Carbonaceous mudstone is a common embankment material with the characteristics of water softening and water disintegration, which often causes the instability of embankments. This paper presents an experimental work on the ...
Characterization of Volumetric Crack Rate and Its Influence on Unconfined Compressive Strength of Red Clay
Publisher: ASCE
Abstract: Desiccation cracking is a common phenomenon for red clay due to alternating wet and dry weathers. The presence of cracks definitely affects the strength of the soil; however, characterizing the development of desiccation ...
Axial Stress–Strain Model of LRS-FRP–Confined Rectangular Concrete Prisms Allowing for the Size Effect and Its Application in Flexural Analysis of Beams
Publisher: American Society of Civil Engineers
Abstract: Large rupture strain fiber-reinforced polymer (LRS-FRP) composites exhibit a large rupture strain exceeding 5%, thereby enhancing the ductility and strength of concrete as a confinement reinforcement with notable energy ...
