Abstract

The vertical and torsional vibration basic frequency estimation formula of suspension bridge on "Wind resistant Design Specification for Highway Bridges" is introduced. Finite element model of HUMEN suspension is established. Whole vibration models and frequency are obtained by modal analysis, and it lays the foundation for further developing the flutter analysis and spectral analysis of structure. Results of the comparisons of specification and finite element model show that the results agree well. It indicates that specification estimation formula can accurate reflect the dynamic characteristics of the structure. Early in the design, the specification formulas can be used to estimate the fundamental frequency of the suspension bridge.
