Aeolic and Seismic Structural Vibrations Mitigation on Long-Span Cable-Supported Bridges

Herein, two models of long-span bridges, namely a suspension and a cable-stayed one, are developed at the numerical level in a commercial finite elements code, starting from original data, and they are used to simulate the structural response under wind excitation and seismic excitation. The main goal of this study consists in the evaluation of a control strategy, designed and proven effective for the wind action, considering the suspension bridge, or for the seismic action, for the cable-stayed one, when the bridge structure is subjected to the seismic and the wind action respectively.
