Abstract:State-space stochastic modeling (Itô-type) is employed in this study to numerically investigate the relevance of modeling errors in the aeroelastic loading on the flutter stability of a long-span bridge. The main features of the numerical model are: (i) linear time-domain representation of aeroelastic load based on indicial-function formulation, perturbed by a suitable "parametric error"; (ii) turbulence-induced buffeting load still retained in the dynamic equations; (iii) linear bridge response restricted to … Show more
