The structure design of the outdoor large scale Ferris wheel should be meticulous and reliable.
The outdoor large scale Ferris wheel’s structure is different from the general steel structure and the ordinary high-rise structure. It is a very special structure. The Ferris wheel is a permanent ride that is designed to comply with not only the relevant specifications of the building structure, but the specifications of the amusement ride.
The early Ferris wheel is mostly in the form of rigid structure, and the roulette adopts the truss structure system. However, the disadvantage of the full weight of the truss structure also limits the further development of the height of the Ferris wheel. With the development of the technology level, a certain number of flexible cables or The brace strip replaces the truss in the rigid structural form, forming a rigid-flexible combination; when the flexible cable further replaces all the spoke members in the disc, only the rigid truss structure with one turn of the edge of the disc, greatly reducing the roulette. After its own weight, it formed the flexible form adopted by most giant Ferris wheels, making it possible to build a taller and larger Ferris wheel.
At present, there are few reports on the design method and construction technology of the Ferris wheel in China, which are special and challenging. For the outdoor large Ferris wheel, on the one hand it can be compared with the height of some super high-rise buildings, on the other hand the diameter of the wheel has reached the scale of the large-span structure. Faced with this difficulty in integrating super-high-rise and long-span structures, it requires a novel structure that can achieve smooth rotation. The careful selection of analytical design methods, the carefulness of the analysis process, and the authenticity of the results are particularly important.
