| Abstract: | Baishahe extra Long Span Bridge is located in the 8 degree seismic area. A seismic analysis should be made on it. According to the standards of the three-level seismic design, a spectral analysis and elastic time-history analysis were made by use of the finite element program ANSYS, and the inelastic time-history analysis was done by use of the self-programmed program in which the Takada Tri-line model was adopted. The analytical results indicated that the bridge has a good performance in resisting earthquakes. |
