Background technology
Currently, more than earthquake seven degree of (seismic acceleration 1.5g) areas, octave or octaves area carry out tier building or
During Designing Structures of High Rising Buildings, several structure types below generally use：
The first is reinforced concrete frame structure, and this concrete frame structure is typically first true according to vertical bearing capacity
The size in fixed column section, it is essentially identical for across the identical post component of post, its column section；When story drift is inadequate, can lead to
Unified increase column section size and beam section size are crossed to meet to require.However, it is increased using unified increase beam cross-section
The mode of lateral deformation stiffness, it can cause shorten the first natural vibration period of original structure, rigidity increase, seismic force also accordingly increases, from
And cause new lateral displacement stiffness of structure deficiency；Meanwhile the entirety that unified increase beam cross-section can not also increase original structure is antitorque
Rigidity, i.e. ordinary reinforced concrete frame structure is to be difficult to meet that the calculating in highlight lines area requires.
Second is complex high-rise frame-shear wall structure, in this frame shear wall structure, is mainly utilized
Shear wall undertakes the seismic shear of the overwhelming majority, and framework is then used as second defence line, to undertake based on vertical load, because
This, shear wall disposal in structural perimeter, can be obtained preferable torsional rigidity and lateral deformation stiffness by this structural system.However,
This frame shear wall structure system is applied in highlight lines area (such as the very long area of seven degree of areas, Characteristic Site Periods, octave
Huo Jiudu areas of area) when, because shear wall is more dispersed, the rigidity of monolithic shear wall is excessive, and the seismic force of absorption is excessive, shear wall
It is easy to produce destruction, it is more obvious in multilayer and small high-rise；Unless shear wall piece is short and scattered, so can just be not easy to produce
Raw to destroy, but such structure narrow space in building function, arrangement is dumb, using being functionally restricted, therefore should
Structural system can not be widely suitable for the multi-rise building in highlight lines area.
The third is reinforced concrete frame braced structures, and this structural system is that bracing members are arranged in into structural perimeter, tool
There is preferable torsional rigidity.However, there is the shortcomings that similar, the i.e. rigidity due to frame-brace structure in it with Frame-Shear Wall
Also larger, the seismic force of absorption is more, same with the frame column that bracing members are connected easily to produce destruction, especially bracing members and beam
The node location of post.Other bracing members also have certain influence when being arranged on the outside of building on building function and Facade form,
During indoor arrangement, the space for also influenceing building uses.And diagonal brace node is also complex in terms of implementation of constructing, to construction team
Technical requirements it is higher, therefore the utility ratio in multi-rise building is not equally high.
To sum up, be badly in need of design it is a kind of can be applied to Areas of High Earthquake Intensity area and with good anti-lateral displacement and it is antitorque just
Degree, while internal using space is big, space is flexible and changeable, construction easily multi-rise building structure.

Please also refer to Fig. 1 and Fig. 2, for the structural representation of strong frame frame structure provided in an embodiment of the present invention.This
Inventive embodiments provide strong frame frame structure 100 include be arranged on building structure periphery be used for form strong border structure 10
Some frame columns 11 and some frame beams 12, and if be arranged on inside building structure be used for form bearing wall and frame structure 20
Dry inside casing post 21 and interior grid beam 22.Wherein, the column section of the frame columns 11 is more than the column section of inside casing post 21, the frame beam 12
Beam section be more than interior grid beam 22 beam section.
Strong frame frame structure 100 in the present invention, the larger column section of frame columns 11, frame beam 12 can be relied on larger
The strong border structure that is formed of beam section and its residing bezel locations, attract larger seismic shear and tilting moment, from
And it is caused to be different from the problem of torsional rigidity existing for common frame structure is weak and the cycle is bigger；In addition, strong frame frame
Frame structure 100 exists also different from the shear wall in frame shear wall structure and due to rigidity concentrations causes serious earthquake
The excessive bearing capacity on the contrary of power is inadequate, the problem of biasing destruction occurs.
Further, since the column section of the frame columns 11 in the present invention is significantly greater than the column section of inside casing post 21, frame beam 12
Beam section be significantly greater than in grid beam 22 beam section, therefore, in middle shake and big shake analysis, there is frame beam 12 to go out first for it

Cross 35m.In addition, the strong frame frame structure of the embodiment of the present invention is it is not recommended that for six degree of areas of earthquake and non-antidetonation area.
Wherein, because the strong border structure undertakes more horizontal earthquake shearing, the column sections of frame columns and frame beam
Beam section is larger compared to the beam cross-section in common frame structure, thus the seismic force ratio that absorbs of strong border structure between
Between the shear wall of frame shear wall structure and the outer rim of frame-generic structure, i.e. the seismic force that the frame columns absorb is relative
For shear wall less and uniformly, and seismic force that the frame absorbs is more for the frame of frame-generic structure and have pin
To property.
Specifically, the story drift of strong frame frame structure as the present invention and the relative storey displacement of common frame structure
When angle is equal, the first natural vibration period of the strong frame frame structure is substantially basic with the first natural vibration period of common frame structure
It is equal, and then it is much smaller than the antitorque natural vibration period of common frame structure the antitorque natural vibration period of strong frame frame structure, i.e. this
The antitorque integral rigidity of the strong frame frame structure of invention is much larger than the antitorque integral rigidity of common frame structure.
Similarly, the structure first of strong frame frame structure of the invention is more than corresponding Frame-Shear Wall knot natural vibration period
First natural vibration period of structure, while the integral rigidity of strong frame frame structure is less than the entirety of corresponding framework-shear wall structure
Rigidity.Wherein, the corresponding frame shear wall structure refers to the inside casing of the bearing wall and frame structure corresponding to strong frame frame structure
Post, the cross-sectional sizes of interior grid beam are constant, while peripheral frame beam cross-section and inner frame beam cross-section are of substantially equal, and on periphery
Increase the structural system of shear wall.

Rigidity of the strong building structure on periphery.The column section of inside casing post 21 is also rectangle, the long side of the post of inside casing post 21 preferably with building structure
The short side of rectangle plane be arranged in parallel；Correspondence, the short side of the column section of the inside casing post 21 and the rectangle plane of building structure
Long side be arranged in parallel, and to realize the building structure of rectangle, rigidity is close or identical in the two directions.It is understood that conduct
Another embodiment, the flat shape of the building structure are alternatively approximating square, and now, the column section of the frame columns 11 can
For rectangle, the column section of inside casing post 21 can be set to square.
Further, the flexural rigidity of section ratio of the column section of frame columns 11 and the column section of inside casing post 21 is preferably 1: 3
~15, the flexural rigidity of section ratio of the beam section of the beam section of frame beam 12 and interior grid beam 22 is also preferably 1: 3~15.It is preferred that
Ground, the bending stiffness ratio of the column section of the frame columns 11 and the column section of inside casing post 21 are adjusted to 1: 7 or so, frame beam 12
The bending stiffness ratio of beam section and the beam section of interior grid beam 22 is adjusted to 1: 8 or so, for example, when the column section chi of frame columns 11
Very little when being 900mmx1200mm, the column cross-section size of the inside casing post 21 can be 550mmx750mm.It is understood that at other
In embodiment, the ratio of the flexural rigidity of section of the column section of the column section of the frame columns 11 and the inside casing post 21 can also be 1: 3,
1: 4,1: 5,1: 6,1: 8,1: 9,1: 10,1: 11,1: 12,1: 13,1: 14 or 1: 15 etc..Similarly, the beam section of the frame beam 12
