| Abstract: | Cross-section and oblique-section fatigue behavior of bridges were studied in this paper. Based on the study, fatigue design methods of reirdoreed concrete strueture were suggested. The fatigue strength permissible values of RPC and reinforeing steel in the member were determined. The results would be helpful for the fatigue design of bridge. |
