온도 영향을 고려한 특수교량의 열차 주행안전성 평가

In designing railway infrastructures, engineers investigate temperature load only in the process of checking components’ stress, not that of evaluating running safety or ride comfort. As the long-span bridges are widely used in high-speed railway, temperature gets a more and more important factor to make bridge deformed upward or downward. However, there are no way to consider temperature effect on running safety and ride comfort. Therefore it is aimed to make a reasonable criteria and procedure to check them, and to apply such a procedure into the in-situ bridge model.
