Problems solved by technology
The roofs of the above-mentioned actual engineering projects that have been completed all use flexible membrane materials as the roof covering materials of the stadium. The deformation of the roof structure is relatively large under the action of load), and if a rigid roof is used, it will be difficult to meet the large deformation of the roof, which will lead to the destruction of the rigid roof cladding under the external load
On the other hand, since the cost of flexible membrane materials for roofing is still relatively expensive compared with traditional rigid roofing materials at this stage; at the same time, the material life of flexible membrane materials is shorter than the design cycle of building structures, and roof membrane materials may be damaged due to aging during the use stage of building structures. In addition, the natural vibration period of flexible roof membranes is sensitive to wind loads, and resonance is prone to occur at specific frequencies, resulting in large-area tear damage of roof membranes under wind loads.

The invention discloses a spoke type cable-supported cross grid semi-rigid tension structure system which comprises a rigid outer ring beam arranged on the outer edge of a tension structure; the rigid radial beams are arranged at the top of the tensioning structure and are arranged at the top of the tensioning structure in a radial radiation manner; the middle vertical supporting rod is arranged in the middle of the tensioning structure; the middle annular inhaul cable is arranged in the middle of the tensioning structure and located below the middle vertical supporting rod; the external radial inhaul cable is arranged at the lower part of the tensioning structure; the internal annular inhaul cable is arranged at the opening position of the tensioning structure; and the internal radial supporting rod is arranged in the tensioning structure. The structural system has the characteristics of a spoke type tensioning structural system and a rigid grid structural system, the flexible inhaul cables and the rigid cross grids form the overall stress structural system, the structural system is in a self-balancing tensioning state under prestress, the good structural overall rigidity is achieved, and the structural system is suitable for being used in the field of engineering construction. The roof structure can be used for an internally-opened large-span space building roof structure.
Description
technical field [0001] The present disclosure relates to the technical field of large-span space building structures, in particular to a wheel-spoke cable-bearing cross-grid semi-rigid tension structure system. Background technique [0002] With the continuous progress of building materials and building technology, the span of large-span space structures is getting larger and larger, and the traditional structural system cannot meet the development of large-span space structures. The traditional rigid frame structure, arch structure, truss structure, and reticulated shell structure appear complex in the super-span space structure, so the tension structure system with cables and membranes as the main components appears in the large-span space structure. [0003] In recent years, the spoke tension structure system has emerged as a large-span space structure, which is widely used in non-enclosed large-span buildings (such as stadiums, football fields, etc.) with openings in the...
