Towards the Standardization of Wind Loads on Membrane Structures: Hyperbolic Paraboloid and Cone

Abstract Wind loading is a governing design action for lightweight membrane structures due to their low mass and geometric sensitivity. However, current standards provide limited guidance for doubly curved forms, and available aerodynamic data remain fragmented. This study investigates the wind‐induced behaviour of different typical shapes through atmospheric boundary layer wind tunnel testing and this document present the results for two of the geometries. Pressure measurements on both surfaces were used to derive net pressure coefficients and identify characteristic loading patterns. Results show pronounced suction near windward edges and regions of higher curvature, with reduced gradients toward leeward areas. Comparison with literature demonstrates consistent global trends, while deviations are mainly linked to geometric differences as well as differences in inlet flow conditions. The public availability of the experimental data, together with ongoing numerical studies, supports the use of these geometries as benchmark cases for coordinated research and future updates of membrane design standards.
