Parametric analysis and dynamic tests of bridge and building complex structural system

A new combination structure of station and bridge has been appeared in the high-speed railway and track projects.It is necessary to research its composition form,structure properties and seismic effects.In the paper,the bridge and building complex structural system is proposed as a new seismic structural system,and The configuration,simplified model and the formulation of the 2-degree of freedom equations of motion for the structure are provided.The optimal parameters are obtained from parameter optimization analysis has been done.A steel frame complex structural model with energy dissipation devices is designed in our research for a large scale shaking table dynamic test.The research results show that the complex structure has good reduction vibration effect.
