| Summary |
The membrane material doesn't have the structural stiffness in general and the shape exists in the uncertainty. Therefore, on the membrane structure, a form-finding analysis and a cutting pattern analysis different from a conventional structure are necessary before the analysis of the mechanical behavior. Because the membrane material is extremely light, the grasp of the mechanical behavior considering the influence of the air reaction with the membrane vibration is important. In this paper, after the structural morphogenesis analysis (cutting pattern analysis with form finding) is executed to the membrane structure, the numerical example of time-history response analysis of the primary evaluation to consider the added-mass effect in air is indicated. Time history wind loading adopts the fluctuating wind velocity data that consider the phase shift to the perpendicular, depth, and horizontal direction. In the numerical example, the difference of the mechanical behavior by the presence of the phase shift by the fluctuating wind velocity data and the presence of the added-mass addition is clarified by using a HP-shaped suspension membrane structure. |
