| Abstrait: |
Three damage modes of cable-suspended structures are summed up on the basis of experiences. A model scaled to be one eighth of a real cable-suspended bridge is established. The dynamic tests of the model in non-damage mode and the three damage modes are carried out respectively by applying white-noise and El Centro waves of different intensities to the model. The structural systems keep stable and the members of the model are not damaged, even though the maximum longitudinal and transverse accelerations applied exceed an equivalent of 0.4gfor a real structure. It means that the cable-suspended structures of pipelines, even in the three damage modes, have a good seismic resistant capacity in earthquake of intensity IX in China. |
