| Abstract: |
A new method of iterative buckling analysis is proposed for obtaining the effective length of steel tower members in cable-stayed bridges. The concept of a fictitious axial force, which is derived from the relation between the individual buckling limit of each member and the overall buckling of the bridge, is introduced to overcome the problem associated with system buckling analysis. After presenting the proposed method, it is applied to an example cable-stayed bridge with different girder depths. The results demonstrate that the proposed method not only provides reasonable outcomes by correcting the inaccuracies seen in system buckling analysis, but is also convenient for practical applications. |
