RISAutomated Identification of Pavement Structural Distress Using State-of-the-Art Object Detection Models and Nondestructive Testing
Publisher: ASCE
Abstract: The rapid identification of structural damage in pavements remains a challenging issue. This paper proposes an automatic identification method that combines nondestructive testing, the ground penetrating radar (GPR), and ...
Project Management in the Chinese Construction Industry: Six-Case Study
Publisher: American Society of Civil Engineers
Abstract: Originating from the West, project management was introduced into China after the country’s economic reforms in the 1980’s and has since spread quickly throughout the whole country, particularly in the construction industry. ...
New Model for Simulating Hydrologic Processes under Influence of Surface Depressions
Publisher: American Society of Civil Engineers
Abstract: Surface depressions significantly influence hydrologic processes. In traditional semidistributed models, however, the entire area is connected to the outlet of a watershed and surface depressions are often lumped as a ...
Modified Calculation Model for Segment Floating in Slurry Shield Tunnel
Publisher: ASCE
Abstract: Concrete remains the most commonly used material for lining segments in shield tunnels. Extensive segment floating can easily result in segment dislocation, crack damage, and water leakage. Based on the river-crossing ...
Influence of Zonal Variation of the Subtropical Westerly Jet on Rainfall Patterns and Frequency of Heavy Precipitation Events over East Asia
Publisher: American Meteorological Society
Abstract: Understanding the effects of zonal variation of the East Asian subtropical westerly jet (EAWJ) on spatial features of heavy precipitation events requires characterization of the shape, orientation, position, and scale of ...
Characteristic Differences of CrIS All-Sky Simulations of Brightness Temperature with Different Microphysics Parameterization Schemes
Publisher: American Meteorological Society
Abstract: Influences of cloud liquid water, cloud ice, rain, snow, and graupel on all-sky simulations of the Cross-track Infrared Sounder (CrIS) brightness temperature (TB) are assessed for the 399 data assimilation (DA) channels. ...
Explainable Machine-Learning Model for Rapid Damage Assessment of CFST Columns after Close-In Explosion
Publisher: ASCE
Abstract: In the present study, the dynamic response and damage of concrete-filled steel tubular (CFST) columns under close-in explosion were numerically studied. An extensive parametric study was carried out to investigate the ...
Hydration Hardening of Early Strength Low-Heat Cement under a Low-Pressure Environment
Publisher: American Society of Civil Engineers
Abstract: The limited early strength of low-heat cement (LHC) restricts its extensive application. This work compared the hydration degree, hydration products, and pore structure of the early strength of low-heat cement (ESHLC) in ...
Green Fabrication of Superhydrophobic Zeolite Coating on Cement-Based Material Surfaces to Improve Water-Resistant and Anticorrosion Properties
Publisher: ASCE
Abstract: Constructing a superhydrophobic coating on cement-based materials’ surface can effectively inhibit the invasion of external water and corrosive ions. However, current strategies of fabricating superhydrophobic coatings ...
Modeling the Deterioration of Inductive Loops
Publisher: American Society of Civil Engineers
Abstract: Inductive loop detectors have been widely used in transportation system, particularly to monitor the performance of highway systems such as traffic flow, speed, and vehicle classification. Accurate data are dependent on ...
