Study on Buckling-Characteristics of Single-Layer Latticed Domes subject to Initial Imperfection (II) (Part II In the case of Pinned-Joint)

단층래티스돔의 좌굴특성에 미치는 형상초기부정에 관한 연구 (II) (제II보 핀접합의 경우)

Compared with rigid-jointed latticed dome, in pinned-joint latticed dome, results of Ref.1 showed reduction of buckling strength by decline of junction's rotational rigidity. Moreover, with decline of junction's rotational rigidity, geometrical initial imperfection incurs more and more reduction of buckling-strength. This study, subsequently the case of rigid-joint domes, is aimed at analyzing buckling-characteristics of pinned-joint single-layer latticed domes with triangular network subjected to initial imperfection.
