Abstract
  • In this paper the numerical computation of the dynamic response to turbulent wind excitations of slender structures is addressed. A numerical procedure capable to effectively estimate the three-dimensional structural behavior is proposed, based on a direct frequency domain approach. A probabilistic description of the wind velocity field, accounting for the correlation between the turbulence components, is combined to a linearized fluid-structure interaction model, under the quasi-steady hypothesis. We propose robust implementations of multiple right-hand side and multiple shift Krylov subspace methods with deflation of basis vectors, which allow us to efficiently analyze the dynamic response for a wide range of frequency values and wind time histories. Numerical experiments are reported with data stemming from real structure modeling. (literal)
