Abstract

An experimental investigation was conducted to investigate the effects of railings on the torsional vortex-induced vibration (VIV) of a single-box girder bridge. This study undertakes a comparative analysis of the torsional VIV characteristics of a bridge girder in two configurations: with railings and without railings, and provides a detailed analysis of the periodic wake flow features. The results show that the VIV characteristics of the bridge, including the initial wind speed, the peak vibration amplitude, and the lock-in range, are significantly influenced by the presence of railings. Flow field visualization tests reveal that, compared to the bare girder, the girder with railings generates larger-scale vortex structures in the wake and exhibits an altered vortex shedding mode.
