This paper instancing of Harbin Sifangtai Cable-Stayed Bridge, simulates two kinds of non-linear bridge tower model considering the pile - soil - structure interaction and not considering using ABAQUS6.8 software. By comparing the frequency, modal, displacement of the tower top, acceleration of the bridge tower and stress of the tower bottom under two circumstances, analyzing and obtaining the conclusion that the seismic response results will be very different to a long-span Cable-Stayed Bridge, whether considering the pile - soil - structure interaction or not.

In this thesis, based on the design of a 140+90m span unusual single tower and single cable plane cable-stayed bridge, free vibration characteristics and seismic response are investigated; three dimensional finite element models of a single tower cable-stayed bridge with and without the pile-soil-structure interaction are established respectively by utilizing finite element software MIDAS/CIVIL, seismic response of Response spectrum and Earthquake schedule are analyzed respectively and compared. By the comparison of the data analysis, for small stiffness span cable-stayed bridge, the pile-soil-structure interaction can not be ignored with calculation and analysis of seismic response.

Cable Stayed Bridge

Taking the Sifang Bridge in Yunnan Province in China as an example, this paper analysis the influences of soil-structure interaction on seismic response of extradosed cable-stayed bridge with response spectrum method. The results show that extradosed cable-stayed bridge has a shorter nature period than cable-stayed bridge, and torsional vibration mode does not happen in the first few modes as the beam has a bigger stiffness. The displacement of the structure will be underestimated if the soil-structure interaction is ignored while the design of some parts is conservative.
