RISDevelopment of Emergency Track Beam Alignment for Rapid Track Beam Replacement of Straddle Monorail Transit
Publisher: American Society of Civil Engineers
Abstract: Prestressed concrete (PC) track beams are the important component of straddle monorail transit systems. To ensure the normal operation of straddle monorail transit, a type of prefabricated steel track beam, termed an ...
Effect of the Late-1990s Change in Tropical Forcing on Teleconnections to the Amundsen–Bellingshausen Seas Region during Austral Autumn
Publisher: American Meteorological Society
Abstract: Tropical sea surface temperature (SST) and associated precipitation, acting as diabatic heat forcing, has far-reaching climatic impacts across the globe through exciting poleward-propagating Rossby waves. It is found that ...
Time-Dependent Properties and Model Analysis of Rheology for Fresh Sulphoaluminate Cement Paste Evaluated by Electrochemical Impedance Spectroscopy
Publisher: American Society of Civil Engineers
Abstract: In this paper, the time-dependent properties of rheological parameters (τ0, η, A) and electrochemical parameters (Rb) are investigated by preparing sulphoaluminate cement pastes with different water-to-cement ratios (W/C) ...

Air Flow Modeling in a Prototype Sanitary Sewer System
Publisher: American Society of Civil Engineers
Abstract: Modeling air movement in sewer systems is important because of its importance in addressing sewer odor issues and pipe corrosion. In this study, a steady-state model was developed for simulating the air pressure and movement ...
Effect of Different Lime-Anhydrite Ratios on the Hydration Process of Sulfoaluminate Cement
Publisher: ASCE
Abstract: In this paper, the influence of lime-anhydrite (L/A) ratio on the strength development, cement hydration, and setting time of calcium sulfoaluminate cement (CSA) is systemically investigated. Based on Raman spectroscopy ...
Viscoelastoplastic Constitutive Model for the AC Lower Surface Layer Considering Time-Varying Characteristics during the Intelligent Compaction Process
Publisher: American Society of Civil Engineers
Abstract: Intelligent compaction (IC) technology based on the continuous compaction control (CCC) technology enables real-time monitoring, evaluation, and feedback of compaction quality. However, the lack of a viscoelastoplastic ...
Analysis of Crack Microstructure, Self-Healing Products, and Degree of Self-Healing in Engineered Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: In this paper, self-healed cracks of engineered cementitious composites (ECC) are observed by optical microscope and scanning electron microscopy, and self-healing products of ECC are analyzed by X-ray diffraction technology. ...
Camera Calibration Method Exploiting Reference Images and Roadway Information for Traffic Applications
Publisher: American Society of Civil Engineers
Abstract: A video-based traffic flow detection system requires calibration of cameras to generate accurate estimates of vehicle speed. Traditional manual calibration methods cannot satisfy this requirement because calibration has ...
