Static Nonlinear Analysis of Cable-Stayed Bridge and the Adjustment of Stay Cable Forces

The static nonlinear analysis of the cable-stayed bridge has been worked out in terms of plane member system. The nonlinear behaviors of the cable-stayed bridge having one-tower and multistay cable are on trial. The adjustment of the cable forces on dead load and the cable tension for constructional stage are studied. In the meanwhile, the above calcu- lating results are obtained by linear analysis and nonlinear analysis respectively. Significant conclusions are drawn from a comparison between the two.
