| Abstract: | The homogeneous solution derived from the governing differential equations was used as the displacement patterns of finite segment. The stiffness matrix and load column matrixes are obtained in terms of directed stiffness method and working energy principle. A program is designed to calculate the curved girder bridge. An example was given, comparisons between force method and the matrix delivering method are presented to testify the accuracy of the above method. |
