Abstract

This paper proposed the design bending moments of cantilever slabs with KL-510 load according to span length of long span decks. Their span length range is from 6.0 to 12.0 meter, and length of cantilever slabs is from 30 to 50 percent of their span length. The effects of orthotropic concrete decks, stiffness of steel girders and multiple lane loading factors (MLLF) were reflected in the design bending moments. The proposed design bending moments of cantilever slabs were compared to the design bending moments with DB-24 load.

본 연구에서는 현행 도로교설계기준의 KL-510 하중을 적용하여 장지간 바닥판의 내측 지간에 따른 캔틸레버 바닥판의 설계휨모멘트를 제안하였다. 장지간 바닥판의 내측 지간은 6.0~12.0m 범위를 대상으로 하였고, 캔틸레버 바닥판의 길이는 내측 지간의 30~50%를 적용하였다. 설계휨모멘트의 결정을 위해 바닥판의 직교이방성, 거더의 강성, 그리고 다차로재하계수의 영향을 반영하였으며, 이를 기존의 DB-24 하중에 대한 설계휨모멘트와 비교하였다.
