Problems solved by technology

[0011] In view of the problems existing in the prior art, the purpose of the present invention is to overcome the defects of low lateral stiffness and poor ductility of the prefabricated concrete structure and the deformation of the prefabricated steel structure by taking advantage of the steel-concrete composite structure without formwork, good ductility and high rigidity. Large defects and defects of prefabricated components of the prefabricated steel-concrete composite structure are complex and cast-in-place shear walls are used, and the innovative prefabricated steel-concrete composite structure system is used in prefabricated super high-rise residential buildings

Abstract

The invention belongs to the technical field of buildings and particularly relates to a fabricated super-high-rise steel-concrete combination residence. The advantages that formworks are omitted, ductility is good and the rigidity is large of a steel-concrete combined structure are utilized, the defects that as for a fabricated concrete structure, the resistant-lateral rigidity is small and the ductility is poor, as for a fabricated steel structure, deformation is large, and as for an existing fabricated steel-concrete combination structure prefabricated member, the structure is complex and cast-in-place shear walls are adopted are overcome, and an innovated fabricated steel-concrete combination structure system is applied to the fabricated super-high-rise residence. The fabricated super-high-rise steel-concrete combination residence is composed of concrete-filled steel pipe combination columns, externally-wrapped steel-concrete combination beams, steel plate combination shear walls and energy-dissipation-type concrete-filled steel pipe combination buckling constraint supports to serve as the structure system of the super-high-rise residence, and thus the defects that as for the fabricated concrete structure, the resistant-lateral rigidity is small and the ductility is poor, and as for the fabricated steel structure, deformation is large are overcome.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to an assembled super high-rise steel-concrete combined residence. Background technique [0002] The prefabricated super high-rise steel-concrete composite residence is composed of steel pipe concrete composite columns, outsourcing steel-concrete composite beams, steel plate composite shear walls and energy-consuming steel pipe concrete composite buckling restraint supports. The prefabrication of the steel pipes of the steel pipe concrete composite columns and the double-sided steel plates of the steel plate composite shear walls are completed in the factory. The outsourcing steel-concrete composite beams can be prefabricated as skeletons or integrally prefabricated. Formwork, columns and walls are all free of templates, which greatly improves the assembly rate and construction speed. It is a prefabricated structural system with a very high degree of industrialization. Prefabrica...
