| Abstract: | In the light of the situation that there are no provisions about fatigue load in the highway bridge design codes and specifications in China for the time being, this paper conducts a study of the determination method and principle of fatigue test load for the cable and girder anchorage structure of highway steel cable-stayed bridge, using the specifications abroad and fatigue cumulative damage theories, on the basis of the vehicle load statistic data collected in some cities and on some sections of the National Roads in the country, and also with reference to the traffic volume prediction in the feasibility study of Sutong Bridge and other relevant highway engineering technical standards. |
