A Study on the Presumption of Geometrically Nonlinear Buckling Load of the Single Layer Layer Latticed Dome

단층 래티스 돔의 기하학적 비선형 좌굴하중 추정에 관한 연구

The single layer latticed dome is very sensitive on the slenderness ratio and half open angle of the elements, load condition and the connection type because it is organized by a lot of thin elements, so we have to use the geometrically nonlinear buckling load when the buckling behavior of the structures is analyzed But, it is very difficult to design the single layer latticed domes considered all conditions. Therefore the purpose of this paper is to propose the appropriate design method of the single layer latticed dome considered the geometrically nonlinear buckling load in base on the linear buckling load by the eigen-value analysis.
