Field.
Background technique
With the quickening of urbanization process, the development of building field and technical level are constantly promoted, in addition environmental pollution and
The defect of the influence of problem of resource waste, feature of environmental protection difference existing for traditional architecture system gradually exposes, green assembling type steel structure,
Start to become the main Types of building system.Compared with traditional system, the system construction quality, in terms of,
All have significant advantage." playing with building blocks " is a kind of representative construction method, largely accelerates speed of application,
Engineering funds are saved.It applies it in the design and development of all kinds of building systems, is the main of building field future development
Trend.
Conventional frame support system use linear type diagonal brace, structure centre position punch place there are space it is smaller, but
In practical structures engineering problem, many structures need windowing, enabling hole, need biggish hole, then conventional frame support system
It cannot meet the requirements, and easily at structure a certain position buckling failure occurs for conventional frame support system diagonal brace without energy consumption section.Tradition
Unreasonable the occurrence of will lead to " strong component weak bus " is designed at support body framework binder Column border node, makes structure in earthquake lotus
Load effect is lower to occur serious earthquake, threatens people life property safety.Add existing research shows that carrying out specific aim to bean column node
It by force or takes weakening means that can achieve the purpose that plastic hinge specific region on beam, to protect bean column node, meets " strong
The design requirement of the weak component of node "；Meanwhile floor and beam section it is pre-assembled after be transported to construction site carry out assembly can greatly save it is existing
The time of field concreting；In addition, without repairing or slightly repairing can restore that function can be restored using function after earthquake
Structure is the research hotspot of International Seismic engineering field in recent years, and the lives and properties of people can not only be protected to pacify in earthquake
Entirely, and after earthquake it can also be restored as early as possible using function, therefore the theory for needing to restore functional structure is implemented in new
Structure R & D design work in, with realize building from it is single pursuit collapse resistant capacity to take into account shake after can repair ability turn
Become.
In order to overcome the problems referred above, the invention patent proposes the Self-resetting steel frame center of a kind of big headroom and flange plate
Support system.By increasing novel compositions automatic runback device, the total bearing capacity of beam can be improved and being avoided that combination Self-resetting dress
Set the overstressing load caused by middle drag-line pretension to I-shaped beam section；By the way that dissipative cell is arranged at diagonal brace, when diagonal brace stress
Dissipative cell absorbs energy, prevents diagonal brace from unstable failure occurs, and structure entirety lateral resisting improves, and is improving structure entirety anti-side
While power, overall stability, door opening can be opened up in the position of setting support, keep design form more flexible, be able to satisfy not
Same structure type.
