Description

Bottom-retracted inner-circle and outer-square double-cylinder oblique-crossing grid super-high-rise structure and forming method

Technical Field

The invention belongs to the technical field of structural engineering, and particularly relates to a bottom-indented double-cylinder oblique-crossing super high-rise structure with an inner circle and an outer square and a forming method thereof. The super high-rise finger structure is not less than 100 meters in height, and the bottom indentation finger bottom maximum overhanging indentation span is not less than 20 meters.

Background

The oblique grid system is a super high-rise steel structure system formed by crossing and converging two-way or three-way oblique column members and connecting the oblique column members in a rigid connection mode, and has the advantages of light dead weight, high lateral stiffness resistance, high height and the like, and the lateral stiffness resistance is an important factor for evaluating the mechanical property of the system. The structure system is widely applied to super high-rise large public buildings with commercial, office and other building functions.

The diagonal grid system mainly bears horizontal force action such as earthquake, wind load and the like through vertical grids formed by crossing the diagonal column members. Because the inclined column component is mainly an axial force component, great lateral stiffness can be realized; the inclined column member generally adopts a box-shaped section, and concrete can be poured into the inclined column member for reinforcement when the section size has building limitation requirements.

The double-barrel oblique crossing grid system is a special case of the oblique crossing grid system, and the oblique crossing inner barrel and the oblique crossing outer barrel are formed by crossing steel oblique column members, so that the problem of inconsistent deformation of the concrete core barrel and the oblique crossing outer barrel is effectively solved. The interior of the oblique crossing inner cylinder can be set to have the function of communicating a high atrium building so as to improve the daylighting degree; the planar shapes of the oblique crossing inner cylinder and the oblique crossing outer cylinder can be set to be round, rectangular, polygonal and the like according to building models. Therefore, the reasonable and effective elevation form and the plane shape of the structures of the oblique inner cylinder and the oblique outer cylinder are important factors of the bearing performance of the whole structure system.

Because the building bottom is open molding and functional need, the bottom need set up at times and greatly encorbelments the indentation, adopts lifting conversion multilayer of bottom to encorbelment the truss in order to support the non-floor vertical load in upper portion of some, hangs down through the top setting simultaneously and connects the multilayer truss of encorbelmenting in order to bear the non-floor vertical load in lower part of another part, is a comparatively reasonable effectual solution. Therefore, the structural form and the vertical position of the reasonable and effective upward-lifting conversion multi-layer cantilever truss and downward-hanging connection multi-layer cantilever truss are important factors for ensuring the reliable bearing of the vertical load of the middle non-landing floor, the integral side resistance of the integral stress system and the implementation feasibility.

Through the arrangement of the inclined column members with the retracted bottoms, the vertical floor load on the outer side of the upper part can be effectively converted to a basement roof structure or a foundation structure; the top of the inclined column component is retracted, so that the lifting framework can be supported, and a vertically symmetrical building model is formed. When the non-floor has a large span space locally, the non-floor frame column can be interrupted locally, and a large span steel beam is arranged to realize the non-floor frame column. Therefore, the reasonable and effective arrangement of the bottom indented oblique columns and the connection scheme of the bottom indented oblique columns and the conversion truss are important factors for realizing the effective conversion of the stress and the vertical load of the whole structural system.

In addition, the double-barrel oblique crossing grid super high-rise structure system has the problems of complex node connection structure, complex component structure, bearing performance, rigidity and the like, and the reasonable and effective design and composition scheme of the bottom-indented inner-circle and outer-square double-barrel oblique crossing grid super high-rise structure form is also an important factor for ensuring the bearing performance and normal use of the structure.

In conclusion, it is necessary to research a form and a design method of an inner circle and outer square double-cylinder oblique crossing grid super high-rise structure with a retracted bottom, so as to be suitable for an inner circle and outer square double-cylinder building-shaped super high-rise structure system with a retracted bottom with a large cantilever and an inner elevated atrium, and to bear the super high-rise structure system.
