Honeycomb single-brace-rod type cable dome structure

Abstract

The invention discloses a honeycomb single-brace-rod type cable dome structure. The problems that the structure construction difficulty is large, the joint structure is complex, and the sensitivity height of construction error and component machining error is insufficient exist in the prior art. The honeycomb single-brace-rod type cable dome structure is composed of an upper-chord ridge cable layer, a middle inclined cable and brace rod layer, and a lower-chord ring cable layer. The upper-chord ridge cable layer is a honeycomb sphere and is composed of basic units, and the upper-chord ridge cable layer comprises isosceles triangle basic units on the outermost ring, symmetrical pentagon basic units on the innermost ring, and symmetrical hexagon basic units in the middle. The basic units areexpanded in the circumferential and radial directions, rigid cables, brace rods and inclined cables of the adjacent basic units are collinear, an upper lower-chord point, a middle lower-chord point and a lower lower-chord point are connected by using pulling cables along a ring to form the lower-chord ring cable layer, and the honeycomb single-brace-rod type cable dome structure is obtained. According to the honeycomb single-brace-rod type cable dome structure, the structure is stable, the building shape is concise, attractive and high in spatial effect.

Description

technical field [0001] The invention belongs to the technical field of architecture, and in particular relates to a honeycomb single-strut type cable dome structure. Background technique [0002] The cable dome structure has excellent mechanical performance, beautiful structural shape and outstanding economic indicators. The current research and practice are based on the Fuller concept of "an ocean of cables and an island of compression rods", that is, each upper and lower chord node in the cable dome is equipped with only one vertical compression rod to form a tension field pressure "islands" in Since the horizontal projection of the pressure rod is a point, the projection of the same ring of pressure rods forms a point ring, that is, the pressure rods are perpendicular to the horizontal plane and are not connected to each other, resulting in poor stability. Especially for the rib-ring cable dome structure, the upper chord node has no ring members to constrain it, resulti...

AI Technical Summary

Problems solved by technology

Since the horizontal projection of the pressure rod is a point, the projection of the same ring of pressure rods forms a point ring, that is, the pressure rods are perpendicular to the horizontal plane and are not connected to each other, resulting in poor stability

Especially for the rib-ring cable dome structure, the upper chord node has no ring members to constrain it, resulting in obvious deficiencies in the torsional stiffness and stability of the structure
