“…The structure will be analysed by adjusting constraints to achieve the pretensioning forces ( T i ) in the cables. The constraints used by Janjic et al [ 10 ] to find the optimum cable forces are as follows: there should be no out-of-plane displacement at the top of pylons; there should be no vertical displacement of the deck under dead load. …”

“…As the main purpose of this study is studying the efficiency of the proposed optimization method, the OESC model is applied in this study with low computational costs. The OECS method has also been applied in the literature to optimize the cable forces of cable-stayed bridges [ 9 , 10 , 12 , 37 ].…”

“…A number of approaches have been proposed to obtain the appropriate cable forces of cable-stayed bridges (Wang, Tseng, and Yang 1993;Cheng, Au, and Lee 2000;Bruer, Pircher, and Bokan 2001;Wang and Lin 2002;Janjic, Pircher, and Pircher 2002;Lee, Kim, and Kang 2008). Janjic, Pircher, and Pircher (2002) presented the unit load method (ULM) for the cable force optimisation of cable-stayed bridges based on the idea of Bruer, Pircher, and Bokan (2001). ULM determines adequate factors that should be multiplied to the applied unit loads based on certain desired criteria, such as moments and deflections.…”
