Innovative design of membrane structures
In the state-of-the-art simulation process for membranes, the results of the calculation are restricted to the ideal surface defined by the form finding process without concerning the material direction, the seams and the pre-stressed condition after the assembling of the patches. The cutting pattern itself is generated without consideration of the material and the pre-stress of the yarns. Further, there is no exchange of information between the separated trunks of the design process. There can be a significant difference between the simulation results and the real structure. This leads to wrinkles or areas of very high tension, which can destroy the structure even during the construction process. To take this in account there is the need of a new more detailed simulation approach. In this article, an improved design method for tensioned and inflated membranes is demonstrated. The new concept is to embed the cutting pattern and the assembling procedure into the process chain of the numerical calculation. This ensures a more realistic simulation in consideration of the directions of the yarns, the stiffness of the seams and the shear stiffness of the coated fabric. The combination of a modular calculation framework for the different simulation steps, an independent optimisation of each module and a rule-based system for the design process extends the new concept to an innovative holistic approach.
