Cable-supported bridges show very complex nonlinear structural behavior because each structural member, such as girder, tower, and cables has significantly different structural behavior. Because of the behavioral characteristics, determination of optimum cable tension for securing the target structural shape in a dead load condition is very important as well as prediction of forceequilibrium condition and deformation in design stage. In this paper, a study of advanced initial shape analysis methodology is presented. In the method, a structural shape and a cable tension is continuously updated in every iterative initial shape analysis stage. Performing numerical study, the feasibility of the methodology is investigated.
