The paper concerns aspects of the design and analysis of a very wide span, irregular plan form, air-supported structure at Herford in Germany. A brief review is given of the procedures used in the shape finding, analysis and fabrication patterning of the structure, and of the wind loading modelling from the prestressed to deformed states. Consideration is then given to the question of the overall stability of the structure under strong wind conditions and combinations of wind and snow loading. The wind speed to cause static divergence and subsequent dynamic excitation is qualitatively assessed on the basis of analytical expressions for shallow rectangular regions.
