In order to clarify the rationality of restoring force characteristics of steel pipe column filled with PUFA, the cyclic loading tests were conducted for three types of steel pipe columns, i.e. column with concrete, column with PUFA and steel column only. Then, the effect of smearing polymer on the inner side of steel pipe and the difference of skelton under three kinds of loading, such as one-cycle loading, three-cyclic loading and push over loading, are investigated. Furthermore, the skelton, the hysterical loops, the equivalent stiffness reduction ratio and the equivalent damping ratio of steel pipe column filled with PUFA are proposed. Finally, the buckling phenomena and the seismic performance of steel pipe column filled with PUFA are discussed.
