스팬 300m 단층래티스 돔의 라이즈-스팬비에 따른 좌굴 특성

다국어 초록 (Multilingual Abstract)

As the national income grows, there is a growing demand for buildings that require long span structures such as exhibition facilities, sports facilities, special industrial facilities, and aerospace facilities. Single-layer latticed dome is one of representative llong span structures. But single layer latticed domes are apt to occur the unstable phenomena that are called “buckling” because of the lack of strength of members and instability of structures, etc. In the previous study, the structural stability of a single-layer lattice dome was roughly grasped by a frame structural system using a ready-made steel when a self-weight and a snow load were applied to a single-layer latticed dome having a span of 300 m and a height of 75 m. However, a systematic study of a 300m single layer lattice dome with various rise-span ratios was not performed. Therefore, it is necessary to study various conditions of this structure because the researchers do not have much research data to apply to actual design. Therefore, the purpose of this study is to verify the buckling characteristics of span 300M single-layer latticed dome with rise-span ratio
