Abstract

The work presents a 3D aeroelastic model of a long-span suspension bridge with streamlined deck equipped with leading- and trailing-edge flaps. The objective is to devise a model for the computation of the bridge stability (flutter and torsional divergence) and forced response (buffeting), yet of manageable size to allow for modern control design. The Humber Bridge (UK) is used as a design example. Both fully erected and partially erected conditions are considered. The comparison with previous published data and the results of a preliminary robust controller aimed at increasing the flutter critical velocity and reducing the buffeting are included.
