Abstract

More than half of steel railway bridges are aged over 60 years. The number of steel railway bridges which needs replacement will increase in the near future, and an accurate evaluation of durability of these bridges is required. In such a situation, it is very important to examine load carrying capacity limit state of railway steel riveted girders. Therefore, in order to estimate durability behavior of them, an actual railway girders were examined and tested. Moreover, some nonlinear analyses were executed using an analytical model which takes corrosion into consideration. By using the new method proposed by us, it is possible to evaluate durability of railway riveted steel bridges better than by the current method.
