The purpose of this paper is to grasp the loading capacity of the corroded steel piers. Firstly, we investigate the steel piers which are corroded at the contact area between the steel column pier and the concrete footing. The corroded area and the depth of the corrosion are measured. Secondly, the static analysis is carried out to check the redundancy of a corroded steel pier by increasing the horizontal load gradually. From the results of the static analysis, even though the corroded area is spread on the basement of the steel pier, the initial stiffness and the yield load are not hardly changed. But the displacement after the yielding is increasing with the increasing corrosion depth. Therefore, it must be cautious if large seismic inertia force is applied to the corroded steel pier.
