Abstract

The invention discloses a suspension dome structure suitable for a square boundary and a calculation method thereof. The suspension dome structure includes an upper chord single-layer reticulated shell and a lower chord cable-strut structure, and the lower chord cable-strut structure includes vertical struts, radially cable-stayed Cables and hoop cables, the analysis process includes solving vertical load requirements, hoop and radial stay cable angles, mesh generation based on hoop and radial stay cable angles, and iterative mesh form , calculating the prestress of hoop cables, etc., the present invention deduces the ideal vertical strut support force from the upper load on the basis of the initial shape of the dome, and then deduces the new cable-strut shape and the corresponding upper chord grid shape , and then repeat the above process for the new shape, and iterate several times to get the ideal dome shape. The advantage is that it fills in the blank of using suspens dome on the square boundary, and proposes an explicit solution to generate a suspens dome with internal forces such as hoop cables by correcting the angle of the hoop cables, and the obtained suspen dome structure has ideal mechanical properties.

Description

Technical field

[0001] The present invention relates to the field of building, and more particularly to a chord branch structure suitable for a square boundary and a calculation method thereof. Background technique

[0002] The string branch is a new type of spatial structural system with a string-to-theoretical study and engineering practice in China. In recent years, China's string-string dome structure mainly applies to large spatial structures such as gymnasium, conference hall, exhibition hall, but because of the stress performance of the string of the dome, the choice of the mesh form of the string monolayer net shell has a major relationship, no The reasonable grid form will greatly reduce the structural efficiency of the string branch. When the string branch is applied to the square boundary, due to the shape of the square boundary and circular ropes, it is difficult to coordinate in force, so the string morphology, the identification and finding force of the upper string...

Embodiment Construction

[0022] The invention is further clarified in conjunction with the accompanying drawings and embodiments, and it is to be understood that the invention is intended to illustrate the invention and is not intended to limit the scope of the invention.

[0023] like figure 1 As shown, the present invention is a chord branch for a square boundary and a calculation method thereof, and the string branch contains a string single-layer reticle and a lower string rod system, and the upper string monolayer enclosure includes a radial rod 1 and a ring rod. 2, the lower string rrotor system includes vertical struts 3, radial squash 4 (inverse), and ring-contained cable 5 (ring). The upper string single-layer retaining center node does not provide a vertical strut, and the retaining node 6 applies a prestressed to the cable through the tensile ring.

[0024] like Figure 5 As shown, the present invention applies to a calculation method of a string branch structure of a square boundary, and its an...
