This study analytically examined wind-load effects on bridges supported by temporary bearings during bearing replacement, a stage in which structural stability can decrease. Straight and curved three-span steel composite box-girder bridges were analyzed under wind speeds of 20–50 m/s for four bearing types. Findings show that F-support temporary bearings may experience significant instability, with the possibility of collapse even under a single wind-load event.
