레일-거더 상호작용을 고려한 자기부상철도 강재침목의 응력해석

초록

The previous analytical model which consists of rail and sleeper may not be able to consider the additional deformation of sleeper induced by the girder deflection. Therefore, in this paper, we use an analytical model which contains a girder to consider the rail-girder interaction. The analytical results show that the maximum stresses of the sleeper can be 1.1 ~ 1.5 times larger for the most of load combinations but smaller in the case of load combinations in which concentration load is included when the rail-girder interaction is considered than not considered.
