| Abstract: |
The paper firstly describes the application of a new type of structures to long span steel bridges for high speed railway in China, and then mainly introduces the technique research of fatigue design for long span steel bridges. The research includes two parts. One is fatigue load research on the new type of long span railway steel bridges, the other is fatigue strength on the new type of structure details. Through systematic investigation of fatigue load and fatigue strength with long span railway steel bridges, the fatigue load regulation factors are obtained. Based on the fatigue test results with more than 40 new kinds of structure details, the S-N diagrams are also obtained. The research results play an important part in the technology upgrade for the design of long span railway steel bridges in China. |
