The bridge structure VIV is one of the key issues of wind-resistant design of large - span bridges , especially for are a large number of domestic construction of large-span steel box girder , steel box girder bridge and steel structure continuous beam bridge , its main VIV beam sections has become the focus of the study of wind resistance . In this paper, the Hong Kong-Zhuhai-Macao Bridge and the Xiamen-Zhangzhou Bridge project examples VIV characteristics separate steel box girder and steel box girder integral , and the test results were analyzed . The use of the reliability of wind-resistant design of highway bridges , \The case of use of the the Scanlan experience linear model theory , known vortex induced resonance test parameters , calculated vertical bending vibration amplitude , to verify the impact of the relevant parameters of the vortex-induced vibration . Addition, road and bridge on Nai Chau water three main beam sections VIV of comparative analysis , comparing the dynamic characteristics of the test parameters , test results , analysis of vertical bending baseband , reversing the baseband equivalent mass , equivalent mass moment of inertia , aerodynamic shape the bridge vertical bend vortex induced resonance and to reverse the impact of the vortex-induced resonance .
