Under the long-term effect of traffic load, the cable-girder anchorage zone of the cable-stayed bridge will be continuously subjected to fatigue stress, so the real-time stress state of this part is one of the important factors affecting the safe operation of the long-span cable-stayed bridge. In the present paper, finite element software was used to analyze the stress state of the key nodes of a typical steel anchor box of a long-span cable-stayed bridge, and based on the European, American and Chinese standards, the fatigue strength of the key nodes was evaluated according to the stress results. The evaluation results show that the fatigue strength of the cable-girder anchorage zone can meet the requirements of various codes and can continue to operate safely.
