In the case of a railway bridge where the ratio of live load to fixed load is relatively large, one of the main factors that dominate the bridge life is the fatigue phenomenon that occurs due to long-term accumulation by live load. Therefore, evaluating and constantly maintaining the fatigue life of cables in cable-supported bridges is an important item in ensuring the safety of bridges over their lifetime.
