A Comparative Study on the Buckling Characteristics of Single-layer and Double-layer Lattice Dome According to Rise ratio
라이즈비에 따른 단층 및 복층 래티스 돔의 좌굴특성에 관한 비교연구
Abstract
In the latticed domes which is a set of space frame, buckling is derived if the external force reaches a limitation by the lightness of the material and the minimization of the member section area. these are concerned with a geometric shape, network pattern, the number of layer, and so on. Most of all, the number of layer of the lattice dome is a important factor from the viewpoint of initial and structure design. Therefore this study compared buckling characteristics of single-layer with double-layer latticed domes and investigated the relativity of buckling-stress-ratio and member-density-ratio according to rise ratio to improve that designers could extend the range of .design selection
