Calculation on Internal Force Effect of a High-Speed Highway Prestressed Concrete Extra-Dosed Cable-Stayed Bridge
The Extra-dosed cable-stayed bridge is considered as a new popular type of bridge structure in recent 20 years, whose mechanical properties and economic span both lie between continuous beam (or rigid frame ) bridges and cable-stayed bridges. This design is a double-cable-plane (85+150+85) m prestressed concrete Extra-dosed cable-stayed bridge, whose maximum Design speed is 100km/h and its width is 25.50m. The form of the highway is sextuple line which is 10.75m far away,and the cross-sectional slope is 2%. The girder body adopts three cell and single box, the height of beam takes quadratic parabola relation, which is 5m high at the middle support, while at the side support and the midspan is 3m. Vehicle standard load was applied on the bridge. The design uses Midas/Civil to establish the finite element model that is reasonable and simple, analyzing the structure behavior of the girder body under loading, especially the internal forces of bridge structure under dead load, live load and additional force.
