Mitigation of the Wind Buffeting on a Suspended Bridge by Smart Devices

A suspended bridge model, developed at the numerical level in the Ansys finite element code, is used to simulate the structural response under wind excitation. Advanced structural control solutions are modeled also, with due attention to their feasibility and reliability. Two strategies have been implemented herein for the bridge protection. The control devices are defined as smart systems combining together different features and they are organized in different geometric schemes. The control strategies have been compared to each other and with the uncontrolled onfiguration. Their efficacy is shown and the factors contributing to their positive performance are highlighted.
