유체-구조물의 상호작용 알고리즘을 적용한 막구조물의 해석 = An Analysis of Membrane Structures by Fluid-Structure Interaction Algorithm

다국어 초록 (Multilingual Abstract)

Membrane structures which behave large deformation are apt to vibrate and sensitive to the dynamic load. Wind is main factor for the membrane structure's behavior and affected by its behavior. Thus, it is adequate to consider fluid-structure interaction to analyze membrane structures which are having less rigidity more accurately. In this paper, we applied FSI analysis considering fluid-structure interaction on membrane structures. ADINA as finite element analysis program is used for dynamic analysis of structure and fluid analytical results of FSI are compared with those of CFD. As compared with FSI and CFD results, we find that the effects of fluctuating air force which have influence on stress, pressure and velocity of fluids owing to structure's response can not be ignored. And these differences of results will grow up when it comes to actual large span structure.
