Steel tube concrete poling type truss mixed structure for high-rise and super high-rise buildings

Abstract

The invention relates to a steel tube concrete poling type truss mixed structure for high-rise and super high-rise buildings, belonging to the field of structural engineering of civil engineering. The structure is composed of steel tube concrete poling type truss beams, truss supports and truss posts, wherein a plurality of truss beams and the truss posts are crosswise arranged to form a quadrangular array, and one truss support connected with quadrilateral diagonal points is arranged in each quadrangle; the steel tube concrete poling type truss beams, the truss supports and the truss posts are steel tube concrete poling type trusses, and each steel tube concrete poling type truss is formed by connecting a plurality of steel tube concrete chord members along a length direction; and different steel tube concrete chord members are connected through steel tube concrete web members. The structure has the advantages of clear force transmission, good performance, simple construction, good economy and larger overall dimension of components. Moreover, different truss components can be mutually connected to form various combinations, and the inner space of the truss components can be fully utilized. A shearing wall is removed. The structure is suitable for high-rise and super high-rise buildings to use.

Description

technical field [0001] The invention belongs to the field of structural engineering in civil engineering, and in particular relates to a composite structure of steel tube concrete limb-rod truss for high-rise and super high-rise buildings. Background technique [0002] At present, the number of high-rise or super high-rise buildings built or under construction in my country ranks among the top in the world. According to incomplete statistics, as of 2011, 15 buildings with a height of more than 300 meters have been completed or planned. The design and construction process of these high-rise or super high-rise buildings has also played a huge role in promoting and innovating the development of building technology and building theory. [0003] In the existing high-rise and ultra-high-rise building structural systems, with different types of structural systems and due to the increase in height, the cross-sectional size of the components tends to increase. For example, in the gia...

Problems solved by technology

The webs of the existing truss structures are mostly empty steel pipes or steel structures, and the damage is mostly caused by local buckling of the webs or weld failure, and the strength capacity of the chords cannot be fully utilized
