Embodiment 1

[0042] Example 1: A giant frame-core tube structure system, the building height is 700 meters, the interior is a grid tube type double steel plate concrete composite shear wall core tube, the bottom shear wall core tube is 2.0 meters thick, and the outside is a giant frame structural system. The diameter of the circular steel pipe giant column at the bottom is 6 meters, and the storey height is 5 meters.

[0043] The shape of the external giant frame structure system is hexagonal, and the distance between the opposite sides of the hexagonal giant frame system is 100 meters. There are six circular giant frame columns 1 in the whole building. The diameter of the bottom of the circular steel pipe giant frame column 1 is 6 meters, the height of the building is 5 meters, one refuge reinforcement layer is set at 50 meters, and the span of the ring belt truss is 50 meters.

[0044] The ground floor of the building is a three-storey hollow hall. The entrance of the hollow hall adopts...

Abstract

The invention discloses a slant-leg rigid-frame-type supporting structure of a super-high-rise building mega-frame bottom layer. The slant-leg rigid-frame-type supporting structure of the super-high-rise building mega-frame bottom layer comprises mega-frame columns, a slant-leg rigid-frame-type supporting structure body, cross-supporting structures, annular belt truss beams and a sub-frame structure. The slant-leg rigid-frame-type supporting structure body is arranged between the two mega-frame columns, and the slant-leg rigid-frame-type supporting structure body is composed of two rigid-frameslant-leg columns and a rigid-frame horizontal beam. The lower ends of the rigid-frame slant-leg columns are separately connected with the two mega-frame columns, and the upper ends of the rigid-frame slant-leg columns are connected with the rigid-frame horizontal beam. The upper ends of the rigid-frame slant-leg columns extend upward and are connected with the cross-supporting structures, the upper ends of the cross-supporting structures are connected with the two mega-frame columns, the annular belt truss beams are arranged at the upper ends of the cross-supporting structures, the other cross-supporting structures are connected to the upper parts of the annular belt truss beams, and the annular belt truss beams and the cross-supporting structures are repeatedly arranged alternately upwards. The slant-leg rigid-frame-type supporting structure of the super-high-rise building mega-frame bottom layer has the advantages of large lateral rigidity, good seismic performance and the like.

Description

technical field [0001] The invention belongs to the technical field of supporting structures of giant frames, and in particular relates to a support structure of oblique-leg rigid frame at the bottom of a giant frame of a super high-rise building. Background technique [0002] With the development of super high-rise building structures, the structural system of super high-rise buildings is becoming more and more complex, and the use of obliquely braced giant frame structure systems is becoming more and more extensive. [0003] In actual engineering, the entrance to the ground floor of a giant frame super high-rise building often requires a hollow hall with a height of 3 to 4 floors. The entrance of a super high-rise building requires a tall and spacious building to ensure that people will not feel oppressed when entering the super high-rise building. How to take into account the coordination of the conversion girders of the ground floor hollow hall, the anti-seismic structur...
