    　View Summary

    <p>From the point of view of rational asset management for the steel bridges, it is very important to evaluate slip resistance-keeping capacities on high strength bolted connections with corroded splice plates. Therefore, the tensile tests with corroded spliced plates were conducted in the past study. From the tensile tests, it has become clear that the slip resistance would be decreased with corrosion thinning of spliced plates. However, the causing factor of axial force decline, which are the cause of decline of slip resistance, haven't become clear in details. In this study, FE analysis of tensile tests with corroded splice plates had been conducted in order to clarify the mechanism of axial force decline in high strength bolted connections with corroded splice plates.</p>
