초록

건설관련 설계기술자들에게는 첨단 복합재료구조에 대한 이론이 너무 어려워서 간단하면서도 쉽게 적용할 수 있는 정확한 방법을 필요로 하고 있다. 몇 가지 섬유 배향각을 가진 적층판은 층수가 증가하면 D16, B16, D26 및 B26 강성이 감소하게 되어 특별직교이방성 판처럼 거동함을 밝히고, 간단한 공식들을 개발하여 발표한 바 있다. 대부분의 교량이나 건물의 상판은 형상비가 큰 경우가 많은데, 이런 구조물의 평형방정시에 대한 종방향 모멘트항(Mx)의 영향은 매우 작아서, 더욱 간단한 해석이 가능하다. 본 논문에는 이러한 문제들에 대한 연구 결과를 제시하였다.
