Membrane structures with the Isogeometric B-Rep Analysis (IBRA)

The present contribution gives an introduction to the design and analysis of structural membranes with the Isogeometric B-Rep Analysis (IBRA) which aims on a new approach for a consistent design-through-analysis workflow. Therefore the concept of IBRA is briefly introduced. For the analysis of structural membranes the necessary elements are presented, where the cable element is formulated following the new paradigm of embedded B-Rep edge elements. Benchmarks and application of non-linear analyses and form-finding of structures highlight the potential of the developed framework and the applicability to the design and analysis of structural membranes.      «
