RISPore Structure Characters and Oxygen Permeability Interpreted by Katz–Thompson Model of Fly Ash Concrete
Publisher: ASCE
Abstract: The relationship between the characteristics of concrete pore structures and intrinsic permeability was investigated. The concrete pore structure incorporating fly ash was characterized by parameters including total porosity, ...
Nanoscale Effect on Ultrathin Gas Film Lubrication in Hard Disk Drive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the current thickness of the gas film between the slider and the disk in Hard Disk Drive is already only one order of magnitude larger than the diameter of gas molecules, the nanoscale ...
Isothermal Adsorption Model of Cyclic Water Vapor Adsorption and Desorption for the Whole Range of Relative Humidity for Concrete Material
Publisher: American Society of Civil Engineers
Abstract: AbstractThe water vapor adsorption isothermal model for concrete materials enables the analysis
of microstructural characteristics and an understanding of the material’s hygroscopic
performance. In this study, the cyclic ...
Exploring the Role of Cellulose Nanocrystal in the Hydration and Microstructure of Cement-Based Materials
Publisher: American Society of Civil Engineers
Abstract: AbstractNanocellulose, as an excellent performance, widely sourced, and naturally renewable
nano-reinforced material, shows great application potential in cement and concrete.
This study explored the role of cellulose ...
Experimental Investigation of Lubricant Flow Properties Under Micro Oil Supply Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lubricant flow properties of polyalphaolefin (PAO) oil have been experimentally investigated based on a ball-on-disc configuration under micro oil supply condition. The oil pool shape and central ...
Vibration Control of Stay Cables of the Shandong Binzhou Yellow River Highway Bridge Using Magnetorheological Fluid Dampers
Publisher: American Society of Civil Engineers
Abstract: The Shandong Binzhou Yellow River Highway Bridge is a three-tower, cable-stayed bridge in Shandong Province, China. Because the stay cables are prone to vibration, 40 magnetorheological (MR) fluid dampers were attached to ...
Uniform and Pitting Corrosion Modeling for High-Strength Bridge Wires
Publisher: American Society of Civil Engineers
Abstract: Cable inspections revealed that severe corrosion of steel wires is one of the main failure mechanisms of cables. Accelerated corrosion experiments were conducted to evaluate the variation in the uniform and pitting corrosion ...
Development of High-Strength and High-Ductility ECC with Saturated Multiple Cracking Based on the Flaw Effect of Coarse River Sand
Publisher: ASCE
Abstract: This study developed a high-strength and high-ductility engineered cementitious composite (HSHD-ECC) using coarse river sand (RS) for the first time. Within this newly developed ECC, saturated multiple cracking was achieved ...
Energy Harvesting Using a Torsional Mode L-Shaped Unimorph Structure: Modeling and Experimental Investigations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous studies have proved that the piezoelectric L-shaped beam-mass structure is a good candidate to harvest energy from ambient mechanical vibration. However, most researches merely focused on bending mode of the ...
Convolutional Neural Network Algorithm–Based Novel Automatic Text Classification Framework for Construction Accident Reports
Publisher: ASCE
Abstract: Construction sites remain one of the most hazardous workplaces globally. To improve workplace safety in the construction industry and reduce the personal injuries and socioeconomic impacts resulting from workplace accidents, ...
