Description
Technical field
The utility model is related to building structural element technical fields, in particular to a kind of assembled self- recoverage circle
Concrete filled steel tube combined joint.
Background technology
Steel structure member is by connecting node composed structure system, and the selection of joint form is for structural integrity, reliable
Degree, construction period and Accessory Members design and construction have direct influence.Rotational stiffness is pressed in the connection of frame structural beam and column
Difference can be divided into rigid connection, flexible connection and varied rigid link.
For at present, the design that is rigidly connected is most widely used, and traditional frame beam column rigid joint can be divided into entirely again
Welding node, bolted and welded connection and it is bolted three kinds of forms.Research finds that first two type of attachment is held when earthquake occurs
Brittle break easily occurs because of beam-ends weldquality problem and cannot get effective protection due to, and conventional node form all exists and destroys
After be difficult to repair, the problem of reinforcing, the problem of will necessarily thus causing node point reliability to be difficult to ensure either waste of material.
Self-recovering function structure is a kind of novel shockproof control structure, it can not only protect the life of people in earthquake
Property safety can also help people after violent earthquake, reset normal life as early as possible, be that one of seismic design of structures is ideal
New direction.Self- recoverage structural system includes mainly replaceable structural elements, swinging structure and automatic runback device etc..In recent years,
Studies have shown that structure waves the Ductility Design demand that can reduce geological process and structure itself, reduce eaerthquake damage, saves
Structural cost.It is constrained between constraint or component between loosening configuration and basis, structure is made only to be pressurized at basis or component contact surface
Ability and without tension ability, then structure is waved under geological process, so that structure is resetted by prestressing force, forms Self-resetting knot
Structure.This new structural systen effectively control structure " maximum distortion " and can reduce structure " residual deformation ".
Current many scholars realize ground at the frame structure system bean column node center place of setting a roof beam in place provided with prestressed cable
The function that structure resets after shake, short beam Duan Yuzhu only need picture at the construction field (site) by completing connection in factory's stretch-draw prestressing force rope
The common the same method of girder steel by bolting entirely or the intermediate beam section of bolted and welded connection installation, without stretch-draw prestressing force draw by scene
Rope facilitates construction, improves construction quality and reduce the set-up time.But for using the steel pipe of high tensile reinforcement in intercolumniation
Combined concrete node is required study and is developed in terms of realizing intercolumniation Self-resetting.
