| Abstract: | A rigid frame bridge with high pier-long span was taken as a research project,whose space model was built up by utilizing the finite element program MIDAS.The dynamic property of the bridge was calculated,and the frequencies and mode shapes of the bridge were obtained.The analysis provided theoretical basis for further study of the seismic response,wind response and vehicle-bridge interaction about this bridge. |
