| Abstract: | Combining with crossing-ocean cable-stayed Fanhe Harbour bridge engineering example. The author rapidly acquires the influence matrix with related software on the basis of the theory of influence matrix method and calculates the optimum cable tensions of the Fanhe Harbour bridge in dead load state. The results meet the requirement of the specification and engineering calculation accuracy. The method is simple and convenient to find out the optimum cable tensions under dead loads, worth considering. |
