STUDY ON BUCKLING BEHAVIOR AND SEISMIC PERFORMANCE OF STEEL PIERS WITH CORROSION DAMAGE NEAR GROUND

Abstract

Steel structures constructed during the period of high economic growth have been aging for more than 50 years since construction, and corrosion has been found at the boundary of concrete in steel piers. Previous studies have confirmed by seismic response analysis of steel bridge piers with a rectangular cross section that the corrosive damage at the corners reduces the seismic performance of steel bridge piers. Therefore, in this study, the effect of corrosion damage at the edge of concrete of steel bridge piers with a rectangular crosssection was investigated in detail on the buckling behavior and seismic performance of structure.
