Three damage modes of cable-suspended structures are summed up on the basis of experiences. Amodel scaled to be one eighth of a real cable-suspended bridge is established. The dynamic tests ofthe model in non-damage mode and the three damage modes are carried out respectively by applyingwhite-noise and El Centro waves of different intensities to the model. The structural systems keepstable and the members of the model are not damaged, even though the maximum longitudinal andtransverse accelerations applied exceed an equivalent of 0.4g for a real structure. It means that thecable-suspended structures of pipelines, even in the three damage modes, have a good seismicresistant capacity in earthquake of intensity IX in China.
