Above-mentioned wall of High-building cylindrical shell building system have employed Frame-Shear wall, Frame-Shear wall refers to the structural system that the frame system that is made up of peripheral beam column and central cylinder form jointly, the building structure that outside framework comprises Vierendeel girder 3 and is arranged between Vierendeel girder 3, exterior frame column refers to the combining structure that peripheral post 2 and Vierendeel girder 3 are formed, the main Lateral Resistant System of structure is hollow core cylinder, by the synergy with outside framework, to provide enough anti-side and the torsional rigidity of structure.Be characterized in that form of structure is conducive to improving the stress performance of structural entity, thus improve high-rise building anti-seismic performance.Frame-Shear wall becomes because of the flexibility of its good stress performance and inner space the predominate architecture form adopted in current international super highrise building, has a wide range of applications in super highrise building.
But also there is following defect in above-mentioned wall of High-building cylindrical shell building system:
One, owing to arranging shear wall 5 in cylinder in hollow core cylinder cylinder, in cylinder, shear wall 5 weight is excessive, increases the seismic forces of basic load and structure, and cost is high simultaneously.
They are two years old, outside framework is connected with hollow core cylinder by Vierendeel girder 3, connection between Vierendeel girder 3 and hollow core cylinder belongs to varied rigid link, here varied rigid link has certain relative displacement or relative deformation between shear wall 5 in referring in peripheral hollow core cylinder and hollow core cylinder cylinder, part moment of flexure can only be born, there is certain corner, and be connected by shear wall in cylinder 5 in hollow core cylinder, rigidity is very large, belong to and be rigidly connected, here be rigidly connected relative displacement in referring in peripheral hollow core cylinder and hollow core cylinder cylinder between shear wall or relative deformation very little, almost nil, that is hollow core cylinder is connected in order to an entirety with shear wall in the cylinder in cylinder, there is relative deformation hardly, cause the internal force of hollow core cylinder excessive, be unfavorable for the performance in the defence line, exterior frame column two road that peripheral post and Vierendeel girder are formed.
Because old specification is to the fire protection requirement of high-level structure, the Frame-Shear wall area of plane can not more than 2000m
2, and the fire compartmentation regulation flooring area of plane of new criteria can exceed 2000mm
2, in practical engineering application, floor area reaches 3000m
2above, floor area is large, and the area of Core Walls Structure also can increase, thus causes the shear wall in Core Walls Structure too much, and preponderance, economy is bad.
Summary of the invention
The object of this invention is to provide a kind of frame hollow core wall structure system of highrise building, this structural system can reduce the weight of hollow core cylinder, reduce the seismic forces of basic load and structure, reduce cost, the effect in defence line, exterior frame column two road can also be given full play to.
Above-mentioned purpose of the present invention realizes by following technical solution: a kind of frame hollow core wall structure system of highrise building, this structural system comprises shear wall, coupling beam, peripheral post, Vierendeel girder and floor, described shear wall is positioned at the center position of highrise building, shear wall is the vertical multi-disc arranged, between adjacent shear wall, erection has described coupling beam, shear wall and coupling beam collar form a hollow core cylinder, described peripheral post is positioned at the periphery of hollow core cylinder, peripheral post is the many steel core concrete columns vertically arranged, Vierendeel girder is also many, part frame erection is between peripheral post and shear wall, remaining Vierendeel girder is erected between two adjacent peripheral posts, it is characterized in that: the inside of described hollow core cylinder is also staggeredly equipped with many cylinder inner beams, the two ends of cylinder inner beam are overlapped on shear wall respectively, to reduce the weight of hollow core cylinder, reduce the seismic forces of basic load and structure, and can cost be reduced.
Structural system of the present invention, by cancelling shear wall in the cylinder in hollow core cylinder, changes into and adopts cylinder inner beam overlap joint, significantly can reduce the weight of hollow core cylinder, reduce the seismic forces of basic load and structure, and can reduce cost.Simultaneously, outside framework is connected with hollow core cylinder by Vierendeel girder, connection between Vierendeel girder and hollow core cylinder belongs to varied rigid link, and in hollow core cylinder, adopt cylinder inner beam overlap joint, formed hinged between cylinder inner beam and hollow core cylinder, in the cylinder of therefore hollow core cylinder, outside cylinder, be varied rigid link, there will not be the situation that local stiffness is excessive, more can give full play to the effect in the defence line, exterior frame column two road that peripheral post and Vierendeel girder are formed simultaneously.
