Design Formulas of Electromagnetic Inertial Mass Dampers for Cable Vibration Mitigation

This study proposes the design formulas of an inerter-based damper termed electromagnetic inertial mass damper (EIMD) for bridge stay cables. To maximize the modal damping ratio for a specific cable vibration mode, we derive the design formulas of the optimal inertance coefficient and damping coefficient of the EIMD, respectively. The accuracy of the design formulas has been validated via a numerical simulation and a full-scale experimental...
