Outline of Final Research Achievements	As the result of the tensile tests of SBHS steel, SBHS steel has a high yield ratio and low ductility compared with normal steels. Based on the tensile tests, the parameters of Three surface model are determined. The 1-directional cyclic tests of the steel pier specimens with 1/10 scale are conducted. The hollow and CFT pier specimens are used. In addition to the displacement and reaction force, the cracks and the local strain at the bottom of the specimens are measured. The applicability of Three surface mode to the seismic analysis of the piers with SBHS steel is examined by comparing the results of the experiment.
