Year: 2025

Type: article

Abstract: To investigate the impact of inhomogeneous wind sites on the aerostatic stability of a long-span suspension bridge in mountainous canyon terrain, this study focuses on such a bridge as its subject. Initially, extensive wind measurements were conducted at the bridge site. The data revealed significant variability in wind speed and angle of attack across the bridge’s span, highlighting the wind’s inhomogeneity. Subsequently, a nonlinear analysis method was developed to model the bridge’s static response to the inhomogeneous wind field, integrating empirical wind data and segment model tests. This method was validated through wind tunnel simulations of the inhomogeneous wind field and comprehensive aeroelastic model tests of the full bridge. The results indicate that the inhomogeneous wind field significantly affects the bridge’s aerostatic stability. These findings offer valuable insights for related studies.
