Vibration Control for Bridge Towers and Field Measurement

Abstract

In Japan, steel towers are widely employed for the cable-supported bridges mainly due to high seismic design forces. Steel towers of suspension and cable-stayed bridges are very flexible and have generally low natural frequencies. In addition, the structural damping of towers tends to be low. Furthermore, tower shafts have usually rectangular or other aerodynamically bluff cross-sections. As a result, they are extremely susceptible to wind effects, particularly at their erection stage, and would suffer from wind-induced vibration such as vortex-induced vibration and/or galloping if no countermeasures are taken.
