Membranes are extremely light and slender constructions which results in a high susceptibility to wind-induced deformations and vibrations. For the analysis of the complex aeroelastic phenomena, emerging from the interaction of the structural response and the wind flow around it, a partitioned fluid-structure interaction method is proposed. Nearly massless structures interacting with incompressible fluids demand for an iterative coupling scheme, which is enhanced by adaptive under-relaxation for stability and efficiency. The performance of this approach is analyzed in several real-world examples.
