The study focused on figuring out how much stress a bridge deck can handle before getting tired. Researchers looked at the Hong Kong-Zhuhai-Macau Bridge and studied the fatigue load of specific weak spots. By analyzing real traffic data, they created a model to mimic the stress on the bridge. The results showed that their method is useful for designing against fatigue and can help with similar structures. They also found that they can accurately simulate traffic loads using a specific method.
