A TMD system using a rotating inertial mass damper is proposed to reduce vertical vibration of structural beams and floor slabs subject to walking excitation. The developed TMD is comprised of a ball screw mechanism including flywheels and springs. This system has proved to have significant mass effects because of the ball screw mechanism, even with a small mass of the flywheel. The TMD system was applied to the connecting bridge. The authors carried out the vibration measurement of the connecting bridge and ascertained the efficacy of the newly developed TMD system.
