Abstract EN
The stiffening girder of self-anchored suspension bridge (SSB) is subjected to huge axial force because the main cable is directly anchored on the end of the stiffening girder.
To obtain a simple model and accurately understand the mechanical behavior of the whole structure in preliminary design, this paper proposed an analytical calculation method considering the combined effects of the main cable-suspender-stiffening girder.
On the basis of the deflection theory of the stiffening girder, the relation between the girder shape and the suspender force was explored.
The relation between the main cable end force (MCEF) and the suspender force was derived through segmental catenary theory, and iteration method was further improved to avoid the divergence condition.
Finally the solution was obtained through satisfying the compatibility condition.
The proposed method does not need to iterate manually and can save calculation time.
Examples are introduced to verify the applicability of this method, with the result that this method considers the combined effects of the main cable-suspender-stiffening girder, and the finished bridge state satisfies the minimum strain energy of the stiffening girder.
Results also indicate that this method has fast convergence speed and high precision.
