On the Wind-induced Vibration of Large-span Bridges

With the develop of large-span bridges,the control of wind-induced vibratory is very important.The main forms of wind-induced vibratory of large span bridges generally include buffeting,vortex-induced resonance and vibration storm,whose impact on the structural safety can not be ignored.This paper discusses the design principles of large span bridges and the control of wind-induced vibration,and then comes up with some measures to improve the bridge structure and increase the mechanical damping.
