Multi-objective optimal design of TMDs for increasing critical flutter wind speed of bridges

Tuned mass dampers (TMDs) to improve long-span bridges' critical flutter wind speed have been widely investigated. However, the optimization of the parameters of TMDs to increase the aerodynamic stability of the long-span bridge girders in the most efficient way has not been properly considered...
