영문 초록

After measuring actual stress by two measurements(Dynamic Strain Meter, Histogram Recorder)on truss rail road bridge, we could perform time history analysis by 3-D beam element method on modelling bridge. And then,after analyzing bridge structure in static by 3-D modelling, we estimated degree of fatigue damage in main member, secondary member of tie zone,cutting area of base metal cross section for confirming the result. In case that the simulate stress is carried out on medeling bridge, most of those simulation mainly is performed by main members.But in real bridge fatigue damage problems generally caused by junctions, connections, joints in which especially local stress is activated. Therefore, in this paper actual stress on critical area was estimated through the analysis result by simulation. With this study, we can estimate the degree of fatigue damage from a safety point of view and comparative accuracy.
