Firstly, cyclic loading test of steel pipe column filled with PUFA was performed to grasp its elasto-plastic response characteristic. The results of the steel pipe column filled with PUFA were compared with those of the steel pipe column without PUFA and those of the steel pipe column filled with concrete. Nextly, earthquake resistance of an existing steel arch bridge built in 1955 was evaluated by nonliner dynamic analysis and steel arch ribs were retrofitted by PUFA. We clarified stiffening effect comparing behaviors of the bridge retrofitted by PUFA and concrete. Through these two studies, we confirmed effect of new seismic retrofit method for steel structures using PUFA.
