볼 조인트의 휨 강성 영향을 고려한 단층 래티스 돔의 좌굴하중에 관한 연구

초록

A single layer latticed dome is one of the most efficient structures because of its low specific gravity. For easily analyzing of a sinlge layer latticed dome, joint system is assumed to be pin or rigid joint. However, its joint uses ball whose system has intermediate properties of pin and rigid joint. Therefore this study has a grasp of bending rigidity, stress and mechinical properties through experimental and analyzing method of the bolt inserted ball joint. To analyze the stress of bolt and sleeve, this study uses through 3D elastic contact and cubic element, and then the ball and the bolt are perfectly connected for easily analyzing.
