Abstract
The utility model relates to a semi-rigid steel frame structure of eccentric supports, which comprises a semi-rigid steel frame and a plurality of single sway rod type eccentric supports. The semi-rigid steel frame is formed by connecting a plurality of frame columns and a plurality of frame beams in semi-rigid mode, the eccentric supports are arranged between an upper frame beam and a lower frame beam, and two ends of the eccentric supports are in rigid connection with the frame beams. In the structural system, the frame with the eccentric supports is used for bearing horizontal load (such as wind load and horizontal earthquake effect), the other frames are used for bearing vertical load (such as structure self-weight, floor live load and the like), division of work is clear, and stress is reasonable. The eccentric supports are capable of remarkably improving lateral force resisting rigidity of the semi-rigid steel frame and improving performance of the semi-rigid steel frame.
Description
Technical field
The utility model relates to the building construction types in a kind of civil construction field, a kind of specifically eccentric semi-rigid steel framed structure that supports.
Background technology
Liang Yuzhu in the conventional steel frame construction adopts and is rigidly connected; Along with a large amount of uses of high-strength bolt in connection; The connected node of some beam and post is difficult to make and is rigidly connected; Like end plate bolt connected node, T-steel connected node, angle steel connected node etc., so Semi-rigid Connection Steel Frame (being called for short semi-rigid steel frame or ANALYSIS OF STEEL FRAMES WITH SEMI-RIGID CONNECTIONS) is an objective reality.Semi-rigid steel frame is compared with the traditional rigid connection steel frames; Has long, advantage such as anti-seismic performance is good natural vibration period; But the anti-side rigidity of structure is low, sidesway is big, is difficult to satisfy instructions for use, and therefore needing to introduce a kind of anti-lateral body is to increase the anti-side rigidity of semi-rigid steel frame.At present common anti-lateral body is that all kinds of vertical support (comprising center support, the eccentric support), steel plate shear force wall, reinforced concrete shear wall, steel concrete core tube etc. are arranged; These anti-lateral bodys are the anti-side rigidity that all can significantly improve steel frame, but these anti-lateral bodys are only to be confined in the traditional rigid connection steel frames at present.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art, a kind of eccentric semi-rigid steel framed structure that supports being provided.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of eccentric semi-rigid steel framed structure that supports; It comprises by several frame columns and several Vierendeel girders through the semi-rigid semi-rigid steel frame of forming that is connected; Also comprise several eccentric supports, the eccentric support is arranged at up and down between two Vierendeel girders, and its two ends and Vierendeel girder are rigidly connected.
Said off-centre is supported for the eccentric support of monocline rod-type.
In this structural system; Eccentric two ends and the Vierendeel girder that supports of monocline rod-type is rigidly connected; The eccentric framework that supports of band mainly is used for bearing horizontal loading (like wind load, horizontal earthquake action); All the other frameworks mainly are used for bearing vertical load (like dead load, flooring live load etc.), and the division of labor is clear and definite, reasonable stress.Eccentric support can significantly improve the anti-side rigidity of semi-rigid steel frame, improves its performance.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1. frame column; 2. Vierendeel girder; 3. semi-rigid connection; 4. the monocline rod-type is eccentric supports; 5. active beam link.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; A kind of eccentric semi-rigid steel framed structure that supports; It comprises by several frame columns 1 and several Vierendeel girders 2 through the semi-rigid 3 semi-rigid steel frames formed that are connected; It comprises also that several monocline rod-types are eccentric and supports 4, and the monocline rod-type is eccentric to be supported 4 and be arranged at up and down between two Vierendeel girders, and its two ends and Vierendeel girder 2 are rigidly connected.
Semi-rigid steel frame has shortcomings such as anti-side rigidity is low, sidesway is big, is difficult to satisfy instructions for use; The eccentric support 4 of monocline rod-type is that a kind of anti-lateral body of using maturation is; Semi-rigid steel frame and the eccentric support 4 of monocline rod-type are combined; Be a kind of novel building aseismicity structural system; The applicant is referred to as " the semi-rigid steel framed structure of the eccentric support of monocline rod-type ", and eccentric support can significantly improve the anti-side rigidity of semi-rigid steel frame, improves its performance." the semi-rigid steel framed structure of the eccentric support of monocline rod-type " is different from traditional monocline rod-type steel framed structure, and in traditional monocline rod-type steel framed structure, Vierendeel girder and frame column are rigidly connected.
In " the semi-rigid steel framed structure of the eccentric support of monocline rod-type "; The eccentric framework that supports of band mainly is used for bearing horizontal loading (like wind load, horizontal earthquake action); All the other frameworks mainly are used for bearing vertical load (like dead load, flooring live load etc.); The division of labor is clear and definite, reasonable stress.When carrying out design of building structures, the length of active beam link 5
aCan be by the conventional method value.
Along with the fast development of China's steel building and high-strength bolt a large amount of uses of beam column in connecting; The use meeting of semi-rigid steel frame more and more widely; " the semi-rigid steel frame of the eccentric support of monocline rod-type " is a kind of choice of technology scheme, and application prospect is very extensive.
Claims (2)
1. an off-centre supports semi-rigid steel framed structure; It comprises by several frame columns and several Vierendeel girders through the semi-rigid semi-rigid steel frame of forming that is connected; It is characterized in that; Also comprise several eccentric supports, the eccentric support is arranged at up and down between two Vierendeel girders, and its two ends and Vierendeel girder are rigidly connected.
2. a kind of eccentric semi-rigid steel framed structure that supports according to claim 1 is characterized in that said off-centre is supported for the eccentric support of monocline rod-type.
