Honeycomb three strut cable dome structure

Abstract

The invention discloses a honeycomb three strut cable dome structure. The existing technology has many disadvantages, such as the great difficulty of structure construction, the complexity of node structures, and the less sensitivity to construction errors and component processing errors. The honeycomb single strut cable dome structure is composed of an upper chord rib cable layer, a middle inclined cable and strut layer, and a lower chord ring cable layer; the upper chord rib cable layer is a honeycomb sphere, composed of basic units, and includes a symmetrical pentagonal basic unit of an outermost ring, an isosceles triangle basic unit of an innermost ring, and a symmetrical hexagonal basic unit in the middle; the basic units correspondingly extend in the circumferential direction and the radial direction, and rib cables of the adjacent basic units are collinear; and lower chord points are connected through cables along rings to form the lower chord ring cable layer, and the honeycomb three strut cable dome structure is obtained. According to the honeycomb three strut cable dome structure, the structure is stable, the building shape is simple and beautiful, and the space effect is strong.

Description

technical field [0001] The invention belongs to the technical field of architecture, and in particular relates to a honeycomb three-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, resultin...

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
