초록
The speed of vehicles on both straight and curved bridges is crucial, particularly during bridge usage or when raising the bridge for bearing replacement. This study examines the impact of vehicle speeds of 30, 60, and 100 km/hr on the bearings of straight and curved bridges. By conducting time-history analysis considering the centrifugal force of vehicle loads, the effects of vehicle speed on the bearing reactions and displacements were determined. Results show that the reaction and displacement of bearings on straight bridges are less affected by vehicle speed compared to curved bridges, where these effects increase significantly with speed.
