Real-Time Aerodynamics Hybrid Simulation: A Novel Wind-Tunnel Model for Flexible Bridges
Publisher: American Society of Civil Engineers
Abstract: Despite rapid development in computational fluid dynamics, semiempirical analyses based on parameters identified from spring-mounted sectional models are still widely used to examine wind-induced effects on bridges. In ...
Active Simulation of Transient Wind Field in a Multiple-Fan Wind Tunnel via Deep Reinforcement Learning
Publisher: ASCE
Abstract: The transient wind field during a nonsynoptic wind event (e.g., thunderstorm downburst) presents time-varying mean and nonstationary fluctuating components, and hence is not easy to be reproduced in a conventional ...
Influence of Three-Dimensional Distortion on the Unsteady Lateral Force of a Train on a Streamlined Deck under Crosswinds
Publisher: ASCE
Abstract: This study aims to investigate the influence of turbulent three-dimensional (3D) and distortion effects on the unsteady lateral buffeting force of trains on a streamlined deck and propose a closed form equation for the 3D ...
