Abstract

As for the maintenance of steel bridges, evaluation for deterioration and damage caused by corrosion is important. The authors suggested that fatigue strength of corroded steel plate could be arranged by maximum stress range considering stress concentration due to corrosion surface geometry. However, factors controlling stress concentration and expression for stress concentration could not be obtained. This study aims at proposing fatigue strength evaluation method for corroded steel plates though close observation on corroded steel plate surface, fatigue tests and elastic three dimensional finite element stress analyses.
