Fatigue Characteristics of Steel Railway Bridges

국내 강철도교의 피로특성

In order to evaluate that factors such as span length, member type and train loading affect on fatigue of steel railway bridges, in this paper, a series field tests were carried out for some plate girder bridges. From the result estimated by rainflow counting method to analyses real strain-time curve obtained from the field test, it was known that the fatigue effect is more significant in the bridge having short span length and the secondary members regardless of train load types.
