| Abstract: | In the design process of large span cable-stayed bridge, the influences of diagonal rope sags on the construction must be taken into account. Based on the design plan of Su Tong bridge, this paper analyses the variations in elastic moduli by diagonal rope sags in the stage of finished bridge, and formulates the influences of diagonal rope sags on the internal force and deformation of the stayed-cable bridge. |
