Embodiment 1

[0079] Such as Figures 1a-1f as well as Figure 2-Figure 4 As shown, the multi-directional truss-frame-core tube combination super high-rise structure of the O-shaped chamfered edge includes a supporting core tube, a floor frame, a multi-directional large-span multi-layer truss, a chamfered edge boundary truss, and a non-floor frame. The supporting core tube ( Figure 1b ) is the main component of vertical lateral force resistance, which is composed of several groups of small core tubes arranged uniformly, symmetrically and dispersedly along the circumferential direction of the plane. Figure 1c ) are located in the vicinity of the periphery of each small core tube, combined with the small core tube to form a local monomer structure, and together serve as the end vertical support structure of the multi-directional large-span multi-layer truss; the multi-directional large-span multi-layer truss ( Figure 1d ) includes the arrangement of planes and facades in different orient...

[0096] Such as Figure 11 As shown, the composition method of the multi-directional truss-frame-core tube composite super high-rise structure of the O-shaped chamfered edge comprises the following steps:

[0097] S1. The high zone tube 1 supporting the core tube, the middle zone tube 2 supporting the core tube, and the low zone tube 3 supporting the core tube form the main component of vertical lateral force resistance, which is distributed, evenly and symmetrically arranged around the central positioning point 23 ;

[0098] S2. The frame column 4 of the floor frame supporting the periphery of the core tube, the circumferential frame beam 5 of the floor frame, and the radial frame beam 6 of the floor frame form a floor frame, and together with the supporting core tube, constitute a vertical lateral force-resistant structural system ;

[0099] S3. The upper chord of the hoop truss of the long-span multi-layer truss 7, the middle chord of the hoop truss of the long-span multi-...

Abstract

A multi-directional truss-frame-core tube combination super high-rise structure construction method based on O-shaped beveled edges, based on the main structure combined with multiple groups of small core tubes and surrounding floor frames, and multi-directional large-span multi-layer trusses, and through the oblique cutting Side-space trusses and non-floor frames are treated with boundaries and local large-scale structures to form an overall force-bearing mode of the combined super high-rise structure. Multiple groups of scattered and uniformly arranged small core tubes and floor frames near the surroundings are combined with large A multi-layer truss structure is used to form a super-high-rise core support structure; the building facade shape is realized through the space boundary trusses with beveled edges, and the large space of the local floors is realized through the non-floor frame, which constitutes the overall force mode; through the load-bearing performance analysis, and control the load-bearing Force, overall stiffness and torsional performance, to ensure the overall load-bearing performance of the structural system. and the application that provides the structure. The invention has high lateral rigidity, high bearing capacity, high structural height and unique shape of the façade with chamfered edges.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a composition method and application of an O-shaped chamfered multi-directional truss-frame-core tube combined super high-rise structure. Background technique [0002] Steel frame-core tube system is a super high-rise structural system composed of steel frame and core tube connected by floor steel beams. It has the advantages of light weight, high rigidity, high height and fast construction. An important factor in the mechanical properties of similar systems. This structural system is widely used in super high-rise large public buildings with functions such as commercial offices and headquarters buildings. [0003] When the building plane range is relatively large or there is a full-height open-air atrium, it is a reasonable and effective solution to adopt multiple groups of small core tubes in different positions to disperse. Multiple groups of small...
