초록/요약
The present study determined whether there is collision between girders due to difference in natural period between neighboring vibration systems when a designed earthquake load is applied to a 3-lane 10-span steel box girder bridge with 5-span continuity, which are equipped with friction pot bearings that receive earthquake load, and examined the stability of a formula that calculates the shift of the sliding bearings, which is used in expansion joint design. In addition, this study developed a simple collision evaluation formula directly applicable in determining the possibility of collision.
