ABSTRACT: The prevailing tendency to lightweight and permeable cladding elements demands for thorough investigations of the aerodynamic load assumptions and the resulting structural responses, as current standards in this regard do not allow for an adequate rating. Due to the dynamic properties of prestressed wire-cloth, an adjusted approach for the susceptibility to gust induced vibrations of these structures is to be investigated. In this context, a numerical procedure is introduced to determine gust induced vibrations with respect to the structural nonlinearity. The main focus of this paper has been set towards numerical calculations in the time-domain to investigate the consequences of the nonlinearity with respect to the characteristic deections and the inner normal forces under stochastic wind loads.
