Rotary intersection self-balanced cable truss structure

Abstract

A rotary intersection self-balanced cable truss structure is formed by mutual crossing combination of multi-truss one-way self-balanced cable trusses. The middle of the structure is open, and a roof is arranged on the periphery of the structure. Each one-way self-balanced cable truss is composed of a middle beam or truss, an upper string cable, a lower string cable and a support rod, wherein the upper end and lower end of the support rod are connected with the middle beam or truss and the upper string cable or the lower string cable respectively, the support rod is a round tube, rectangular tube or multi-arm lattice type support rod, and the support rod is hinged to the middle beam or truss and the upper string cable or the lower string cable. The structure has the advantages that an architectural image is attractive, structural stress is reasonable, wind resistance and energy absorption capacity are high, end reaction is small, progressive collapse resistance is high, and machining, manufacturing and installation are easy.

Description

technical field [0001] 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 pipe truss system mainly includes the arch truss system with both ends falling on the edge of the stadium and the multi-truss cantilevered pipe truss system. Composed of struts, the structural efficiency is high, and its main disadvantage is that it usually requires an ...

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, and cable-stayed structural systems. , among them, the pipe truss system mainly includes the arch truss system with both ends falling on the edge of the stadium and the multi-truss cantilevered pipe truss system. The main disadvantage of the existing cable truss system used in stadiums is that it usually requires an outer ring beam (truss) with a large cross-section to balance the internal cable tension; the cable-stayed structure system usually adopts high The giant column on the roof and the cables connecting the top of the column and the roof form the main force-bearing system. The main disadvantage is that the section of the column is relatively large.
