VIBRATION CONTROL OF LARGE-SPAN SUSPENSION BRIDGE WITH TWO-AXLES TMD

Weiping Huang, Qing Shi-Zhong

Open publisher page 0 citations

Abstract

A two axles TMD is presented in the paper, by which the lateral, vertical and torsional vibrations of long-span suspension bridge can be reduced. It is shown that the torsional vibration of a suspension bridge is coupled with its lateral vibration, therefore the 3 vibration modes of suspension bridge can be controlled by a double of two axles TMD.
