| Abstract: |
| QR-method,based on cubic B-spline function and the principle of minimum total potential energy, for analysis of the continuous box-girder bridges is presented.This method has great advantages over the finite element method and the finite strip method.It can be easily carried out on a microcomputer. |
| Key words: box-girder straight continuous box-girder bridges curved continous box-girder bridges QR-method spline function method |
