Seismic Design and Ductility Evaluation of Partial Concrete-Filled Steel Bridge Piers

This paper deals with seismic design and ductility evaluation of partially concrete-filled steel bridge piers supporting highway bridge superstructures. The basic characteristics of the thin-walled steel tubular structures are noted and the importance of partially concrete fill in improving strength and ductility capacity of such structures is explained. A seismic design method for ultimate strength and ductility evaluation of concrete-filled, thin-walled, steel tubular bridge piers is presented. The application of the method is demonstrated by comparing the computed strength and ductility of some bridge piers with test results. The method is applicable for both the design of new, and retrofitting of existing, thin-walled steel tubular bridge piers. The effects of some important parameters, such as width-to-thickness ratio, column slenderness ratio, height of infill concrete and residual stress, on the ultimate strength and ductility of thin-walled steel tubular bridge piers, are presented and discussed.
