recommendations! Published in 2018 at "Journal of Wind Engineering and Industrial Aerodynamics"

DOI: 10.1016/j.jweia.2018.01.039

Abstract: Abstract Although vertical central stabilizer (VCS) on long-span cable-supported bridges is one of practical passive aerodynamic countermeasures, the effectiveness of VCS in improving aerodynamic performance is much dependent on the parameters of VCS. Through a… read more here.

DOI: 10.3390/buildings13051279

Abstract: Suspension bridges’ in-plane extended configuration makes them vulnerable to wind-induced vibrations. Vortex shedding is a kind of aerodynamic phenomenon causing a bridge to vibrate in vertical and torsional modes. Vortex-induced vibrations disturb the bridge’s serviceability… read more here.
