Abstract

This study is aimed at investigating the buckling characteristics of single layer latticed domes with triangular network pattern under the partially concentrated equipment loading in the cases of both having a geometrical imperfection and not having.

구형 단층래스티돔은 강성이 강한 반면 외력이 어느 임계치에 도달하면 좌굴에 의해 구조물 전체의 붕괴가 발생할 수 있다. 특히 시공오차에 의해 발생할 수 있는 기하학적 형상부정과 설비시설 등에 의한 집중하중은 구조물의 내력을 감소시키는 주 요인이 될 수 있다. 본 연구에서는 기하학적으로 형상 부정이 없는 완전계 및 불완전계 구형 단충래티스돔이 설비시설 등에 의해 집중하중을 받을 경우 그 좌굴특성을 검토한다.
