A STUDY ON TENSILE STRENGTH EVALUATION METHOD FOR CORRODED STEEL PLATE

Abstract

Corrosion is typical damage on steel bridges, but evaluation method for strength of steel member with corrosion has not been made clear sufficiently. In this study, following examinations have been performed in order to examine a parameter for arranging tensile and yield strength of corroded steel plate and method for evaluating the strength using the parameter. They are observation of plate sureface onfiguration with corrosion, tensile tests on corroded steel plate extracted from actual steel bridge, and three-dimensional elastic-plastic finite element analyses.
