| Abstract: | Based on the finite element analysis method, dynamic analytical model and motion equation of vehicle-bridge system are established. Separation iteration method is used in solving the equation, and solving program is made in Fortran. On the project background of Ja Xi Bridge in Zhejiang province, the influence of different factors to the dynamic response of highway bridge with high pears and long span is analyzed. |
