In the process, novel structural forms of the beam string, the cable net, the prestressed truss, the suspended dome, the cable dome and the like which are combined with a steel structural system by the prestress technology are produced, the building modeling is greatly enriched, and the bearing capacity of the structure is improved. The conventional cable dome is a space structure mainly composed of ridge cables, oblique cables and ring cables and based on the idea of a tension integral structure, is simple in structure, strong in space spanning capability, light in self weight and high in clear space, and is widely popularized and applied.
In order to meet the requirements of building modeling and structural bearing, the grid size among cable dome members is large, so that a roof system is required to have good spanning capacity, meanwhile, as the cable structure is of a flexible structure and can deform greatly under the action of load, in order to adapt to the deformation characteristic of the cable dome members, the roof system is preferably made of flexible membrane materials rather than rigid plates, and therefore, a tension membrane is mostly adopted as the roof material of the cable dome at home and abroad.
