Problems solved by technology

Since the middle of the stadium is often an open field, the roof is a curved surface with large openings. If the middle part of the rigid upper chord of the tension string structure is set as a large opening structure, the upper chord cannot form a complete shell. To obtain the required rigidity and Bearing capacity is very difficult to design. Therefore, there are no relevant reports on the application of tension grid system to open-air stadiums in the world.

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the drawings.

[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the technology of the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

[0033] Such as Figure 1-6 As shown, a form-finding method for a large-opening cable-supported grid structure includes the following steps:

[0034] a) Split the large opening cable support grid structure into an upper large opening rigid system and a lower tension cable rod system. The struts in the lower tension cable rod system support the upper large opening rigid system. The intersection of the strut and the rigid system with the upper large opening is the upper node of the stru...

Abstract

The invention discloses a shape finding method of a large-opening cable-supported lattice structure. The shape finding method has the advantages that the reasonable support on an upper rigid system by a lower tensioning cable rod system can be realized, the vertical state of a support rod of the tensioning cable rod system can be maintained, the height of the support rod is limited, the attractive building effect is reached when the stress is reasonable, and the shape finding result of the cable rod system can be further corrected, so the structure system can be suitable for various load work conditions, and the stress is more reasonable.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a form-finding method for a large-opening cable-supported grid structure suitable for stadiums. Background technique [0002] The beam string structure has been used for a long time in Europe and Japan. Since steel beams were used for the initial winding, it was called BeamStringStructure in English. In 1986, Professor Masao Saitoh of Nihon University defined this structure as "stretching the strings and combining them with beams", which is called a stringed beam. The stringed structure built earlier, such as a kindergarten gymnasium in Japan, uses parallel stringed beams. The size is 26m×36m. The Nihon University Gymnasium designed by Professor Masao Saitoh also uses parallel beams with a plane size of 58m×85m. [0003] In recent years, the application of string beams has become more and more widespread. The upper chord has also developed from beams to arches, plane t...
