Comparative Study of Dynamic Characteristics of Trough Concrete-filled Steel Tube Arch Bridge
A model of trough CFST arch bridge was established through large finite element analysis software. The modal parameters of the bridge were obtained by modal analysis method. Then the stiffness of a class of members (such as the derricks, crossbars, ties, crossbeams, longitudinal beams, bridge decks) was changed,when other parameters were unchanged. Then different modal parameters were obtained. By comparing the changes of the natural frequencies and vibration modes ,the contributions of different members of the bridge to resist transverse vibration , vertical vibration and twist vibration were obtained. The study may provide a reference for the analysis of modal parameters and design of trough CFST arch bridge.
