RISNumerical and Experimental Investigation on Vortex-Induced Vibration Suppression of a Self-Anchored Suspension Bridge with a Central-Slotted Box Girder
Publisher: American Society of Civil Engineers
Abstract: In this study, the vortex-induced vibration (VIV) performance, mechanism, and control of a self-anchored suspension bridge with the central-slotted box girder (CSBG) under the operating wind velocity of the bridge were ...
Experimental Investigation on High-Mode Vortex-Induced Vibration of a Flexible Stay Cable in Smooth Flow
Publisher: ASCE
Abstract: With the increase in the main spans of cable-stayed bridges, the wind-induced vibration, especially the high-mode vortex-induced vibration (VIV) of the long stay cables has become a concern for many researchers. In this ...
Mechanism and Aerodynamic Countermeasures of Vortex-Induced Vibration of a Cable-Stayed Bridge with Narrow Π-Shaped Girder Sections
Publisher: ASCE
Abstract: In this study, the investigations on the mechanism and aerodynamic countermeasures (ACs) of vortex-induced vibration (VIV) for a narrow Π-shaped girder (NG) section with the aspect ratio of B/D = 5 (B is the width and D ...
Aerodynamic Interference Effects on Vortex-Induced Vibration of Two Parallel Railway– and Highway–Cable-Stayed Bridges with Triple-Separated Decks
Publisher: ASCE
Abstract: In this study, wind tunnel tests were carried out to study the vortex-induced vibration (VIV) characteristics of two parallel long-span railway– and highway–cable-stayed bridges with triple-separated parallel decks. ...
Staggered-Supported Steel Anchor Box System for Cable-Stayed Bridges
Publisher: ASCE
Abstract: This paper presents a novel anchorage structure for stay cables to reduce the load on the concrete pylon. Called the staggered-supported steel anchor box (SS-SAB), this anchorage structure provides self-balancing of the ...
