Flutter Mechanism of Representative Sections for Long-Span Bridges

Haifan Xiang

Abstract

In the field of flutter mechanism research concerning long-span bridges,flutter driving mechanism and flutter modality are two key problems.A two-dimensional 3 degree of freedom(DOF) coupling flutter analysis method(2d-3DOF method) has been introduced to investigate both the relationship between systematic oscillation parameters of three degrees of freedom and aerodynamic derivatives obtained through free vibration method,and the coupling effects of degrees of freedom in flutter instability.With this fundamental method and sectional model tests,the flutter mechanism of two representative sections for long-span bridges,closed box section and two-isolated-girder section are investigated.The influence of the variation of deck configuration on the flutter-driving mechanism and the flutter modality of bridge deck sections are also studied and valuable conclusions are drawn in this paper.
