초록

지중구조물에 많이 사용되는 파형강판 콘크리트 합성단면은 단면의 어려움으로 인하여 아직까지 보수적인 설계방법을 적용하고 있다. 본 연구에서는 LRFD와 LSD의 두가지 한계상태 설계방법을 사용하여 합성단면의 휨과 압축에 대한 소성해석을 실시하고자 하였다. 실험결과에 대한 분석결과 압축강도는 LRFD 해석값이 보다 안전측으로 해석되었으며, 강판의 강재비 보다는 콘크리트 압축강도의 영향이 큰 것으로 분석되었다. 휨강도는 LSD에 의한 해석치가 실험결과와 잘 일치하는 것으로 분석되었으며, 강판 인장강도의 영향을 받는 Hogging moment는 연결부 등의 영향에 의해 강도증가율이 감소하였으나, Sagging moment는 강재비에 따라 선형적으로 증가하는 것으로 분석되었다.

For the composite section of corrugated steel sheet and concrete, which is often used in soil structures, a conservative design method based on the ultimate strength state is still applied due to the difficulty of the analysis of compatibility condition. In this study, plastic analysis was performed on the flexural and axial strength of the composite section using two limit state design methods, LRFD and LSD. As a result of the analysis of the experimental results, the LRFD analysis value was interpreted as a conservative results for compressive strength, and it was analyzed that the effect of the concrete compressive strength was greater than the steel ratio of the steel plate. The flexural strength was analyzed to be in good agreement with the experimental results by the LSD analysis. From the parametric analysis on the design variables, the hogging moment, which is affected by the tensile strength of the steel plate, slightly decreased the increasing rate of the strength due to the influence of the bolts connection, but the sagging moment linearly increased according to the increment of steel reinforcement ratio.
