Double-ring combined super high-rise structure based on vertical face arc-shaped steel frame-support and forming method

Abstract

The invention relates to a double-ring combined super high-rise structure based on a vertical face arc-shaped steel frame-support. The double-ring combined super high-rise structure comprises steel support small frame cylinders, steel support plane frames, inner and outer ring circumferential steel beams, support-free steel beam columns, a roof conversion truss, a single-layer dome net shell and a bottom base structure; the steel support small frame cylinders are located at the positions of building elevator shafts in the four corners of a plane; and the steel support plane frames are located on the two sides of the plane, and the steel support plane frames and the steel support small frame cylinders are arranged in a spaced mode. The double-ring combined super high-rise structure has the beneficial effects that the advantages of high bearing capacity, high lateral resistance and arc-shaped vertical face double-ring combined building modeling function of the double-ring combined super high-rise structure are brought into full play; modeling and functions of a double-ring combined super high-rise building with high bearing capacity, high lateral resistance and an arc-shaped vertical face can be achieved while the self weight is reduced and the bearing performance is guaranteed; the reasonability and effectiveness of the whole structure system are further guaranteed conveniently through control over the bearing capacity, the overall rigidity, the torsional property and other indexes; and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and relates to a double-ring combined super high-rise structure based on a facade arc-shaped steel frame-support and a construction method. The super high-rise refers to a structure height not less than 100 meters, and the double-ring combination refers to a double-ring combined building with a full-height atrium. surface space. Background technique [0002] The steel frame-bracing system is a high-rise steel structure system that improves the structural bearing capacity and lateral rigidity by arranging oblique supports between some frame columns on the basis of the steel frame structure. It has light weight, large lateral rigidity and high bearing capacity. advantage. This structural system is widely used in high-rise public buildings with commercial and office functions. [0003] The lateral force-resistant components of the steel frame-bracing system include the supporting fr...
