Application of indicial functions in bridge deck aeroelasticity
This contribution deals with some recent studies on numerical and analytical models for the evaluation of aeroelastic response of cross-section models of long span bridges. The time-domain indicial approach, whose validity has been only partially investigated in the past, is selected for the modeling of self-excited forces. Sets of indicial function coefficients are estimated for rectangular cross-sections, and their applicability is proven, through time-domain simulations and comparison with experimental tests. Critical flutter condition and dynamic pre-critical and post-critical behaviors are evaluated.
