An Effect of Equipment-Loading on the Buckling Strength of Single-Layer Latticed Domes with Geometrical Imperfection

형상초기부정을 갖는 단층래티스돔의 좌굴내력에 관한 설비하중의 영향

The paper is aimed at investigating the buckling strength of single-layer latticed domes with the geometrically initial imperfection under the uniformly distributed vertical-loading and the partially concentrated equipment-loading. The results show that the effect of initial imperfection on the buckling strength, if the magnitude of equipment-loading is small, is much more sensitive in domes of overall buckling than in domes of member buckling, but with increasing equipment-loading, it is very sensitive both in domes of overall buckling and of member buckling
