Resumen
The present study attempts to predict the fatigue life of the suspenders through the incorporation of in-situ monitoring data into the proposed analytical coupled traffic-bridge-wind platform. The new findings highlight the importance of both wind load and traffic load in predicting the time-dependent fatigue reliability of the suspenders of long-span suspension bridges during their life time. It also brings an in-depth insight into the stress response characteristics of both the long suspender and short suspender under individual wind load, individual traffic load, as well as combined wind and traffic loads. The proposed methodology in this paper could provide essential guidelines for decision-making regarding the maintenance and replacement of suspenders.
