Dynamic Properties of Long-Span Steel-Concrete Composite Bridges with External Tendons
The dynamic performance of large-span steel-concrete composite bridges with external tendons is investigated by deriving the formula of equivalent damping ratios of composite bridges, and by considering the influence of shear connectors stiffness of composite girders, external tendons, and pile-soil dynamic interactions on the dynamic properties of steel-concrete composite bridge. Finite element analysis indicates that the equivalent damping ratio has a significant influence on the dynamic response and damping coefficient adjusted must be conducted in structural dynamic analysis.
