RISFlutter Stability and Mechanisms of Long-Span Truss Girder Bridges in Mountainous Areas under Various Angles of Attack
Publisher: American Society of Civil Engineers
Abstract: Abstract The sensitivity of flutter performance to the angle of attack (AoA) poses a significant
challenge for the aeroelastic safety of long-span truss bridges in complex mountainous
wind environments. This paper investigates ...
Buffeting Forces on Static Trains on a Truss Girder in Turbulent Crosswinds
Publisher: American Society of Civil Engineers
Abstract: Experiments were conducted in a wind tunnel with scaled models to investigate the aerodynamic characteristics of a train on a steel truss girder. Simultaneous surface pressure measurements were conducted under two turbulent ...
Aerodynamic Mechanism of Double Vertical VIV Lock-In Regions of the Triple-Box Girder
Publisher: American Society of Civil Engineers
Abstract: AbstractLong-span bridges exhibit low stiffness and natural frequencies, making them particularly
susceptible to vortex-induced vibrations (VIV). This study, based on a long-span suspension
bridge, investigates the performance ...
Experimental Study of a Wind Field in a Long-span Bridge Site Located in Mountainous Valley Terrain
Publisher: American Society of Civil Engineers
Abstract: The Baling River Bridge is a long-span bridge located in a special mountainous area. The site has a very complicated wind field that is representative of many cases in west China. A terrain model that simulates the practical ...
