Stress Characteristics of Steel Railway Bridges

Despite the number of steel bridges being under in service more than 50 years reaches about $50\%$ in present, the Quantitative estimation in maintenance on steel railway bridges is not possible because a ton of the field data in the bridges have not been plentifully accumulated. Therefore a series of field tests on the steel plate girder bridge and steel truss bridge, the typical types of steel railway bridges, are executed, and the stress characteristics according to the structural types of the bridges are Quantitatively estimated in this study.
