Abstract
The tension sequence problem of the abnormal cable stayed bridge is very complicated. As cable
stayed bridges are highly statically redundant structures, the structure systems are constantly
changing with the construction process and the tension of the cable will affect the stress state of
the structure. And it is important to determine the tension time of the back cable in the cable stayed
bridge. In this paper, we make a construction stages analysis of different tension schemes, and com-
pare various solutions by the parameters of the stress state of the bridge, like the stress of the ca-
ble, main girder and the main tower stress and deformation and so on. At last, we get the optimal
cable tension schemes, which will provide guidance for the construction process and be time savi
