| Abstract: | This paper is concerned with the determination and optimization of the cable forces for(construction) sequences of cable-stayed bridges.Considering the influence of geometric nonlinearity,(shrinkage) and creep of concrete,A method is introduced,it can solve emulation analysis for construction(sequences) of long-span cable-stayed bridges.A program is developed upon this method.Engineering(application) of the developed program in a bridge of Hunnan demonstrates the feasibility of the proposed method. |
