| Summary |
The simultaneous analysis of the form finding and the cutting pattern for the membrane structure has already been indicated by using the finite element technique with coordinates assumption that one of the authors proposed. Its form confirmation is indicated by the test specimen prepared by the cutting pattern of the numerical results, and the effectiveness of the numerical procedure was clarified for the suspension membrane structure. In this paper, the simultaneous analysis of the form finding and the cutting pattern is adopted to the pneumatic membrane structure with an arbitrary boundary shape. In the numerical computation, a smooth curved surface form with a constant curvature and a curvature different according to a position is obtained. Its form confirmation is similarly indicated by the test piece prepared by the cutting pattern of the numerical results. From these results, the finding of our simultaneous analysis for the pneumatic membrane structure with an arbitrary boundary shape is indicated. |
