Specific embodiment
The specific embodiment of the present invention is described in further detail below.
As shown in Figure 1 to Figure 3, the earthquake-resistant building structure of the steel frame with dissipative links of the invention and chiasma type central supported
Including rectangular steel-tube concrete column 10, girder steel（Including being hinged girder steel 121, just connect girder steel 122）, dissipative links 14, support bar 16 etc.
Component, constitutes the dual lateral resisting structure supported with steel frame.For total, support bar 16 are the 1st road defence line, take the lead in bending
Clothes；Dissipative links 14 are the 2nd road defence line, are surrendered again after support bar 16 is surrendered；Girder steel is the 3rd road defence line；Concrete-filled rectangular steel tube
Post 10 is last line of defense, i.e. the 4th road defence line.The steel-frame structure purpose of the present invention is that the entirety for lifting earthquake-resistant structure resists
Shock stability and Lateral resisting ability.
Further to lift economic benefit：For the girder steel inside earthquake-resistant building structure, employing and rectangle are substantially
What steel core concrete column 10 was hinged is hinged girder steel 121（Minority and support bar 16 it is same across just connect except girder steel）.It is hinged girder steel
121 are easy for installing using the benefit being hinged, and will not too much weaken the Lateral resisting ability of system, can set by non-antidetonation component
Meter, without interface ductility demand, width thickness ratios can be C classes section, reduce cost.In the peripheral frame of earthquake-resistant building structure, adopt
Girder steel 122 is just connect with what is just connect between rectangular steel-tube concrete column 10, and adopts such as Q345 higher-strengths grade steel, with
Lift bearing capacity, rigidity and the anti-seismic performance of steel-frame structure.
Support bar 16 is spring layer chiasma type support bar 16, is designed according to only tension, more economical.
Rectangular steel-tube concrete column 10 uses rectangular steel pipe, to make full use of the compressive property of concrete, reduces cost, together
When be easy to be connected with girder steel.To make full use of high strength steel, more preferable lifting steel structural social benefit, except the special component
Outward, girder steel, rectangular steel-tube concrete column 10 typically adopt such as Q345 higher-strengths grade steel.
Dissipative links 14 are the less beams of span in steel-frame structure, and 1.5 meters of usual span, with the post at two ends just to connect, is cut
Face can be with typically just to have connect girder steel 122 identical, but material adopts such as Q235 strength grades low-yield steel, because relatively low bend
The steel of clothes point can properly increase the ductility of coupling beam, and while enable dissipative links 14 to take the lead in surrender, play energy dissipation capacity.
Support bar 16 can need by house type and structural system requirement is arranged, and support bar 16 is hinged and girder steel using two ends
With the node of rectangular steel-tube concrete column 10.Support bar 16 is designed by pull bar, and seismic behavior on the basis of anti-seismic grade of the structures by carrying
Rise one-level to determine, material adopts such as Q235 strength grades low-yield steel, to lift the ductility of support bar 16.
With support bar 16 be located at it is same across the employing of rectangular steel-tube concrete column 10 for just connecing girder steel 122 and two ends just connect,
And sectional dimension is suitably increased than other firm girder steels 122 that connect, while using superpower design, so that after the reinforcing of the plasticity of support bar 16
Just having connect girder steel 122 can surrender, and its material adopts such as Q345 higher-strengths grade steel, so as to just connect girder steel at support bar 16
122 have certain margin of safety.
Rectangular steel-tube concrete column 10 is rectangular steel-tube concrete column, and its filling adopts normal concrete, height with concrete
Reinforced concrete, lightweight aggregate concrete or self-compacting concrete, recommend using C50 or so strong concrete.
The steel frame with dissipative links of the present invention has advantages below with the earthquake-resistant building structure of chiasma type central supported：
1st, without the need for formwork, reinforcing bar, no-reinforcing-bar colligation operation, concrete is not used directly to be poured in rectangular steel pipe, speed of application
Hurry up；
2nd, post makes full use of the intensity of steel, the rigidity of concrete, bi-material to have complementary advantages, and collectively forms a kind of efficient anti-
Side force component；
3rd, it is easy to standardization, modularity, factorial praluction reduces site operation link, reduces on-site noise, dust, gives up
Material pollution, standardization, modularity, the work progress of batch production is easy to ensure component quality, raising engineering quality；
4th, system is dual Lateral Resistant System, possesses multiple defence line, with good anti-seismic performance and anti-lateral displacement performance, can be very
The residential architectures such as house, apartment well suitable for basic, normal, high intensity area.
5th, system has taken into full account the difference of structure Component Importance, the difference of seismic behavior.According to the importance of component
With the difference of seismic behavior etc., to component using different strength grade materials and section, the characteristics of taken into full account component,
Cost is at utmost reduced while ensureing rational in infrastructure safe and reliable.
6th, system has carried out clearly being distinguished on mechanics for beam, employs different connected modes, is guaranteeing that structure closes
While reason is reliable, construction is substantially facilitated, save material, reduce cost.
A kind of above example only present invention embodiment therein, its description is more concrete and detailed, but can not
Therefore it is interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, some deformations and improvement can also be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
