Abstract

<p>Recently, corrosion has been found in cables of cable system bridges. In the case of cable-stayed bridges with a few cables, corrosion may occur to collapse the bridge, therefore it is necessary to evaluate the remaining performance of the bridge. In this study, bridges under service condition are reproduced using FE analysis, and two analyzes are performed. First is corrosion analysis which was carried out reducing the cross section of the cable gradually. Second is loading capacity analysis which was carried out by gradually increasing the load. These two analyzes show the mechanical behavior of the targeted cable-stayed steel bridge with corroded cables.</p>
