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.

Cable Stayed Bridge

The dynamic characteristics of cable-stayed bridge will be affected greatly by soil action. In the paper, a spatial dynamic analysis model of a cable-stayed bridge was built by using the general finite element software ANSYS. The dynamic characteristics of the frequencies and modal shapes are investigated and compared with considering the pile-soil-structure interaction or not. From the analysis, the results indicate that if the pile-soil-structure interaction is taken into account, there will have a significant effect on the dynamic behaviors of bridge.

Calculation Results

As an effective way of passive damping, isolation technology has been widely used in all types of building structures. Currently, for its theoretical analysis, it usually follows the rigid foundation assumption and ignores soil-structure interaction, which results in calculation results distortion in conducting seismic response analysis. In this paper, three-dimensional finite element method is used to establish finite element analysis model of large chassis single-tower base isolation structure which considers and do not consider soil-structure interaction. The calculation results show that: after considering soil-structure interaction, the dynamic characteristics of the isolation structure, and seismic response are subject to varying degrees of impact.
