A Study on Fatigue Behavior near the Cover Plate Weldments in the Plate Girder

Service life of steel bridges depends on fatigue and corrosion. Fatigue damage result from stress concentration and initial defects in the joint of secondary member such as weldments. The objective of this study is to estimate fatigue strength of the cover plate weldments in the plate girder. For this study, fatigue tests, static tests and finete element method has been performed respectively from these results. It was found that our test results were well agreed with other test results and satisfied with the fatigue criterion of AASHTO, JSSC and EUROCODE specifications.
