The Forward-analysis Of The Earth Anchored Cable-stayed Bridge Through Midas/civil

With the development of the social civilization, the design of the bridge has become more and more important. Compared to the other bridges, the cable-stayed bridge are suitable for different span, which provides people more freedom to design the footbridge. The unusual design of the cable-stayed bridge can easily provide people the sense of novelty. The small span footbridges can be widely used in campus, scenic areas, urban centers and other places. The cable-stayed bridges are designed as the footbridges, especially the shape of the small footbridges, which have the strong performance. Such kind of footbridge leaves a vast room for the designers to make full use of their creativities.Based on the study on the cable-stayed bridge by the power station of Turks River of Xinjiang, this paper introduced the design of the cable-stayed footbridge in detail. First, Finding the proper constructed state. Optimizing the proper constructed cable strength. Verifying the structure's strength and displacement under such proper constructed cable strength so as to make sure that we have found the right proper constructed cable strength.Then doing specific analysis of each construction stage. Calculating the construction cable strength of each construction stage in order to make the construction result being close to the proper constructed stage. Verifying the structure's strength and displacement of each construction stage. Last, verifying the structure's strength and displacement under different load combination. Different combination of the load includes. With MIDAS / Civil and other finite element tools, it will be possible for the small and medium design institutions to achieve a breakthrough in the cable-stayed footbridges. In this thesis, we can see that the design of the small span cable-stayed footbridge is much easier than the large span cable-stayed bridges across the sea or the river. The structure molding of the small cable-stayed footbridges, especially the small span footbridges, has a strong performance power and provides the designers vast room for their creativity. The author believes that there will be more design institutions to design the beautiful cable-stayed footbridges to enrich people's daily life.
