| Abstract: | Strain measurement and stress analysis are carried out in the tower anchor range,cable pipes and steel born anchor-range of a single tower cable-stayed bridge undervarious static and dynamic conditions.The frequency analysis of strain-time response signals isPerformed with a fast sampling system and fast Fourier transform.These resultS provide arelisble basis for optimum design and rational use of the bridge. |
