RISFatigue Performance and SCF Calculation Method of CFST K-Joints with Array-Arranged and Circular-Arranged Internal Studs
Publisher: American Society of Civil Engineers
Abstract: To reveal the mechanism by which internal studs enhance the fatigue resistance of concrete-filled steel tubular K-joints (CFST K-joints) and to develop a method for calculating the stress concentration factor (SCF) of CFST ...
Effect of Skeleton Networks on the Bearing Capacity of Large Stone Porous Asphalt Mixes Using the Discrete Element Method
Publisher: ASCE
Abstract: Large stone porous asphalt mixes (LSPMs) have the characteristics of large gaps, large content of coarse aggregate, and large particle size of coarse aggregate. Compared with the traditional asphalt-treated base (ATB), ...
Asphalt-Mixture Force Chains Length Distribution and Skeleton Composition Investigation Based on Computational Granular Mechanics
Publisher: ASCE
Abstract: In asphalt mixtures, external loading transfer paths can be deemed as force chains. The force chains difference can be used to evaluate skeleton structure. In this study, various asphalt mixture virtual specimens were ...
Design of Ultrathin-Seal Asphalt Pavement: Influence Analysis Based on the DEM and Mesoscopic Compaction
Publisher: American Society of Civil Engineers
Abstract: An ultrathin seal serves as a preventive maintenance technology. The design method predominantly relies on engineering experience and lacks a theoretical foundation. In order to investigate the impact of aggregate size, ...
