| Abstract: | A dynamic computation model for Jiu-feng mountain- flexible suspension bridge is proposed. By using the computer program DASF, we have obtained the first nine natural frequencies of vibration in the longitudinal vertical plane. These provide basic data for solving the problems of dynamic respon- se and aerodynamic stability of the structure systems. |
