New damper for tower of long-span suspension bridge
1988
Preserved Fulltext
A new damper, relying on the motion of shallow water in a rigid cylinder, is studied through free Vibration tests of a single-degree-of-freedom model of bridge tower with a natural period of 2 see. For a large damping effect at small amplitude of tower Vibration, it is necessary to tune the sloshing period of the liquid to the natural period of the tower; hence the name Tuned Liquid Damper. Breaking of surface waves, while highly dependent on Vibration amplitude, is the main mechanism of energy
