- Abstract
- In this study, an iterative system buckling analysis to determine reasonable effective lengths of girder and tower members in steel cable-stayed bridges proposed. The proposed method includes the addition of a fictitious axial force to the geometric stiffness matrix with iterative eigenvalue computations. we apply the proposed method to cable-stayed bridges with different center spans and girder depths. The effective lengths of members in these example bridges by the proposed method are compared with those found using conventional buckling analysis.
