Embodiment approach 1

[0013] like Figure 1~3 As shown, a circular cross cable truss structure consists of two parts: the cable truss and the peripheral ring beam 1 . The end of the cable truss is connected to the ring beam 1 . The cable truss is composed of multiple planar cable trusses intersecting each other to form a form with an opening in the middle and a roof around it. The plane cable truss is composed of upper chord stay cables 2, lower chord stay cables 3 and several middle web members 4, the upper and lower ends of the middle part web members 4 are respectively connected with upper chord stay cables 2 and lower chord stay cables 3, and the middle web members 4 The length gradually decreases from the outside to the inside, and the upper chord stay cables 2 and the lower chord stay cables 3 intersect at the ends of the plane cable truss.

Abstract

The invention relates to a circular cross cable truss structure which consists of two parts, namely, a cable truss and a peripheral circular beam or a circular truss, wherein the end part of the cable truss is connected with the circular beam or the circular truss; the cable truss is formed by intersection and combination of multi-truss planar cable trusses to form a mode that the middle is opened and roofs are arranged around the peripheral edges; the planar cable trusses consist of upper cables, lower cables and a plurality of middle web members; upper and lower end parts of the middle web members are respectively connected with upper cables and lower cables; the lengths of the middle web members are gradually reduced from outside to inside; the upper cables and the lower cables are intersected at end parts of the planar cable trusses. The circular cross cable truss structure provided by the invention has the advantages that the building appearance is attractive, the structure stress is reasonable, good progressive collapse resistance is achieved, processing, manufacturing and mounting can be feasibly implemented, and the like.

Description

technical field [0001] The patent of the invention relates to a circular cross cable truss structure, which belongs to the field of large-span space structures. Background technique [0002] Long-span space structures have been widely used in stadiums, and the roofs of most stadiums use space steel structures as their structural stress systems. For gymnasiums, the roof is often closed, and its main structural systems include grid frames, reticulated shells, pipe trusses, string beams, string-supported reticulated shells, and cable domes. For stadiums, the roof is often in the form of an opening in the middle and surrounding roofs. Therefore, compared with the stadium roof without openings in the middle, the integrity of the stadium roof is relatively poor. Its main structural systems include pipe trusses, cable trusses, cable-stayed structural systems, etc. . Among them, the cable truss system used in the middle opening stadium is mainly the ring tension cable truss (also ...
