| Abstract: | A rigid frame bridge with thin-wall high piers was taken as a research project.The space model of the structure was built up by utilizing the finite element program ANSYS and the dynamic property of bridge was calculated,and the frequencies and mode shapes of the bridge were obtained.A useful attempt about this type of bridge is made for a seismic and wind resistance design. |
