Abstract

Experimental and numerical analysis has been carried out in this paper to understand correlation between volume and yield of cellular bulkhead. It was firstly confirmed from these results that the conditions and parameters considered in the finite element analysis were reasonable and realistic due to the fact that the yield loads determined by the two different methods were equivalent in actual. Based on this results, a series of intensive numerical analysis has been further performed and revealed that the yield load varied in direct proportion to the change in the volume of the cellular bulkhead.

본 연구에서는 셀 구조물의 체적과 항복하중과의 상관관계를 규명하기 위하여 실내실험 및 수치해석을 수행하였다. 실험과 해석 결과 산출된 항복하중 값은 양호한 상관관계를 보였으며, 항복하중 값의 산출에 있어서 본 연구에서 수행한 유한요소 해석 기법은 타당한 것으로 검증되었다. 유한요소해석 결과, 셀 구조물의 체적 증가에 따라 항복하중은 증가되었으며 항복하중은 체적 증가비율만큼 증가하는 것으로 나타났다.
