| Summary |
The horn-shaped membrane roof has a curved surface. Therefore, it was expected that the aerodynamic characteristics around this roof are complicated. In almost guideline and national code such as `The Building Standard Law of Japan´, the wind force coefficient on the horn shaped membrane roof is not defined. And also, that has not been sufficiently reported yet. From these reasons, the authors have reported about the wind tunnel test on the horn-shaped membrane roof past few years. In this paper, the wind tunnel test and the FEM analysis for the open type horn shaped membrane roof are reported. On the wind tunnel test, the mean value of wind force coefficient and the peak value of it are indicated. Furthermore, a stress and a displacement of the horn shaped membrane roof against the wind load from tests were gotten by FEM analysis. Finally, the design wind load and the wind tunnel test method for the horn shaped membrane roof were weighed from these studies.
