Based on systematic FSI computations, an added mass & damping modeling technique is suggested to replace expensive FSI simulations by efficient structural dynamic analysis with modeled added aerodynamic coefficients. Utilizing numerically generated wind and FSI simulations of membranes immersed in fluctuating wind flow, the necessity of added mass and damping modeling is demonstrated. Then a procedure to employ the FSI-based model is suggested to get as close as possible to a realistic response using structural analysis only, attempting to save the need to carry out extensive FSI simulations, and making wind tunnel tests on rigid models of membrane structures more applicable. This method has shown an advancement to the typical reduced added mass & damping modeling approaches for horizontally, simply supported, prestressed membrane structures. In this paper, this FSI-based modeling concept is extended to more complex membrane structures.
