RISFine Temperature Effect Analysis–Based Time-Varying Dynamic Properties Evaluation of Long-Span Suspension Bridges in Natural Environments
Publisher: American Society of Civil Engineers
Abstract: Structural modal parameters are greatly sensitive to ambient temperatures. Therefore, false identification of damages may arise in vibration-based health monitoring. In this paper, the dynamic properties of long-span ...
Multiscale Modeling and Simulation of Concrete Free Deformation under the Influence of Environmental Temperature and Humidity
Publisher: American Society of Civil Engineers
Abstract: AbstractThe variation of environmental temperature and humidity alters the distribution of
moisture and heat fields in concrete, thereby affecting the time-varying performance
induced by shrinkage and creep of the concrete. ...
3D Cellular Automata–Based Numerical Simulation of Atmospheric Corrosion Process on Weathering Steel
Publisher: American Society of Civil Engineers
Abstract: In order to reproduce the atmospheric corrosion process of weathering steel (WS), a three-dimensional (3D) cellular automata (CA) based method is proposed. Firstly, the atmospheric corrosion mechanism of WS is described. ...
Terrestrial Laser Scan Planning for Bridge Structures at Complex Sites
Publisher: American Society of Civil Engineers
Abstract: AbstractTerrestrial laser scanning (TLS) planning for scanning (P4S) of bridge structures
in complex environments often faces challenges such as algorithm convergence issues,
inefficient panoramic scanning, and time-consuming ...
