Experimental Investigation of Skew Wind Effects on Vortex-Induced Vibration of Typical Bridge Decks
Guangzhong Gao, Pengwei Zhang, Wenkai Du +3
This study explores the skew wind effects on vortex-induced vibration (VIV) of two typical bridge decks-a closed-box girder and a twin-edge girder-through spring-suspended oblique…
A Closed-Form Design Method for U-Shaped Springs in Aeroelastic Modeling of Truss-Girder Suspension Bridges
Guangzhong Gao, Wenkai Du, Yanbo Sun +3
Aeroelastic model testing is essential for evaluating the wind resistance performance of long-span suspension bridges. In these models, truss girders are commonly modelled by a dis…
A novel real-time aeroelastic hybrid simulation system of section model wind tunnel testing based on adaptive extended Kalman filter
Wenkai Du, Guangzhong Gao, Suhan Li +3
Elastically-supported section model tests are the most basic experimental technique in wind engineering, where helical springs are commonly employed to simulate the two-degree-of-f…
Griffin Plots of vortex-induced vibrations: revealing self-similarity for quick estimation from transient displacement responses
Guangzhong Gao, Suhan Li, Jianming Hao +3
Griffin plot relates the peak amplitudes of vortex-induced vibration to structrual mass-damping parameter, known as the Scruton number. Griffin plot serves as a fundamental tool in…
