Abstract: Two finite element models were built by ANSYS according to the actual cable-stayed pipelines and the test model scaled to one eighth of the actual structure, respectively. Static, modal and earthquake response analysis were conducted for the two finite element models. The results from static and mode analyses show that parameters obtained by finite element model based on the scaled structure agree with those by the model tests. The results of the two finite element models meet the similitude principle. The test model could reflect the performance of the actual structure. In earthquake response analysis and shaking table test, the maxim longitudinal and transverse acceleration responses exceeded 0.4g in the actual scale, but the model members did not damage and the structure kept stable. It is shown that the cable-stayed structure can keep running when the input acceleration is 0.4g which corresponds to Richter Scale 9. The results of earthquake response calculated by finite element analysis showed some discrepancy with the ones by the shaking table test, the reasons of which are discussed in this paper.
