Performance of Multi-TMD in the Towers of Suspension Bridges

This paper studies the convenience of Tuned Mass Dampers for reduction of the gust response for the case of the towers of suspension bridges. For this special typology the design must pursue effectiveness, robustness, and redundancy performance. Suitable solutions are multi-device provisions (MTMD), with distributed mass, frequency, and damping. Increasing robustness of MTMD against mistuning beyond the optimal configuration produces a loss of efficiency: as a result the final choice is determined only at the end of the constructive process. A brief discussion is reported on the weak performance to seismic excitation.
