Numerical Analysis on Spanwise Correlation of Vortex-Induced Force of Split Double-Box Beam

Applied Sciences, 2022
The vortex-induced force of bridges is not synchronized along the span direction. The spatial correlation of vortex-induced force becomes obvious when the span of the bridge structure gradually increases, and the mass gradually decreases.
