Abstract

The protection facilities against the collision of the vehicle should be considered in the design of the bridge by the regulations, but there is no regulation against the collision of the vehicle in the design of the column of underpass. Impact analysis for the column of underpass was performed in order to evaluate the damage of the structure by the collision of the vehicle. Impact analysis was performed according to the various parameters such as material properties of the structure and types and velocities of the vehicle. From the numerical results, the structural damage for the column of underpass by the collision of the vehicle was evaluated and considerations in the design for a column of underpass against the collision of the vehicle were examined.

교량의 교각 설계시에는 설계기준에 의거하여 차량의 충돌에 대비한 적절한 방호시설 등이 고려되고 있으나, 지하차도의 기둥 설계시에는 차량의 충돌과 관련된 규정이 없다. 또한 지하차도의 기둥은 상대적으로 폭이나 두께가 작아서 차량의 충돌에 의하여 큰 손상이 발생할 수 있다. 본 논문에서는 지하차도 기둥에 대한 충돌해석을 통하여 차량의 충돌에 의한 구조물의 손상을 평가하였다. 충돌해석에서는 지하차도 기둥의 물성과 형태 그리고 차량의 속도와 종류 등이 매개변수로 고려되었다. 수치해석 결과 지하차도 기둥이 심하게 손상되는 경우가 있었으며 따라서 지하차도의 기둥 설계시에는 차량 충돌에 대한 적절한 고려가 필요하다.
