Advances in the Form-finding of Structural Membranes

The present contribution presents the application of the newly developed isogeometric B-Rep analysis to the form-finding and structural analysis of structural membranes. Therefore, the necessary basis of the model description is briefly outlined. The result of this approach is the possibility to perform mechanically accurate form-finding (and follow-up analyses) directly within a CAD-environment on a full NURBS-based CAD-model. Selected benchmark examples show the accuracy and robustness of the developed method, assessed against analytical solutions if applicable. Two selected application examples that are entirely treated within the augmented CAD-environment highlight the potential of the method: Using one common model not only facilitates geometrical analysis and preparation of the model, but also allows for smooth and close interaction between design and analysis, which is of crucial importance in membrane design.     «
