Embodiment Construction

[0012] Such as figure 1 As shown, the present invention is a steel plate shear wall structure suitable for high-rise / ultra-high-rise buildings in high-intensity areas, using steel PEC columns instead of ordinary steel frame columns, and consisting of H-shaped PEC columns 1, frame beams 2, and built-in steel plates 3 .

[0013] Such as figure 1 , figure 2 As shown, the H-shaped steel PEC column is a composite column with high strength and most of the rigidity is covered with concrete. The H-shaped steel PEC column is composed of section steel 4, tie bars 5 and concrete 6; The area of ​​concrete 6 is Ac, the material strength of H-shaped steel 4 is Fs, and the axial compressive strength of concrete 6 is Fc, then the strength of H-shaped steel PEC composite column 1 is P=(1.2~1.7) (FsAs+FcAc); H-shaped steel PEC composite The rigidity of the column 1 is 1.4~1.8 times that of the H-shaped steel column 4; the tie bar 5 is welded between the upper and lower flanges of the H-shape...

Abstract

Provided is a steel plate shear wall structure suitable for high-rise / super high-rise buildings in high-seismic-intensity regions. A profile steel PEC pillar is used for replacing a common steel framework pillar, and is composed of an H-shaped PEC pillar body (1), a framework beam (2) and a built-in steel plate (3). The H-shaped PEC pillar body is a combined pillar with high strength and rigidity, and a part of the combined pillar is wrapped with concrete. The H-shaped PEC pillar body is composed of profile steel (4), tie bars (5) and the concrete (6). The tie bars (5) are welded to the portion between an upper flange and a lower flange of the H-shaped steel (4). The pillar top and the pillar bottom are subjected to the densification treatment, so that the pillar top and the pillar bottom are each divided into a densified area (7) and a non-densified area (8).

Description

technical field [0001] The invention relates to the anti-seismic field of high-rise and super high-rise buildings, in particular to the field of steel plate shear wall structures in high-intensity areas. Background technique [0002] The steel plate shear wall has built-in steel plates, and the steel plates are connected to the surrounding frame beams and columns, so as to transmit lateral loads such as wind and lateral seismic forces to the foundation. The edge columns of the steel plate shear wall must not only bear the vertical load of the structure but also resist the bending moment generated by the lateral force, which leads to the high compressive capacity of the edge columns. At the same time, the built-in steel plate will form an obvious tension field under the action of transverse downward force, and the surrounding frame needs to effectively anchor the tension to achieve the purpose of buckling deformation of the steel plate and energy consumption. Therefore, in o...
