Technical field
The invention belongs to construction steel structure engineering fields, and in particular to a kind of connection of accentric support steel construction active beam link
Node.
Background technology
Steel frame-eccentrically braces structure is that support and the rod piece active line of framing component are not intersected in a bit, two supports
Between end or one forms active beam link between supporting base end portion and column, and one kind of energy-dissipating and shock-absorbing can be carried out by active beam link
Structural system.
Earthquake plays main control action in high intensity Zone, structure design, selects to lay particular emphasis on reduction when structural system
Seismic force and raising structure ductility, and pure steel structure has apparent advantage.Steel frame-eccentrically braces structure, has taken into account frame
The advantages of two kinds of structural system of structure and concentrically braced frame, can not only provide efficient anti-side rigidity, superior prolong
Property, mitigate dead load to reduce seismic force, and again can flexible adaptation Core Walls Structure functional requirement, as equipment installation is worn
More, the arrangement in various aisle and door opening.This structural system is applied in the skyscraper in highlight lines area and is had a clear superiority.
Damage of the steel frame-eccentrically braces structure under geological process is concentrated mainly on active beam link, and conventional steel frame-
The active beam link of eccentrically braces structure is not easy to replace or replacement cost is big.
Invention content
The purpose of the present invention is to provide a kind of replaceable consumptions of accentric support steel construction that a kind of power transmission is reliable, easy to replace
The connecting node of energy beam section.After shake being cannot achieve which solve conventional steel frame-eccentrically braces structure active beam link connecting node
Problem can be repaired, and does not reduce its energy consumption effect.
The present invention is that technical solution is：Active beam link is located between the end of two accentric supports；Vierendeel girder and dissipative links
Section horizontal connection；The back absolute altitude of active beam link is less than the back absolute altitude of Vierendeel girder, and active beam link and the floor at top is made to disengage；
The end of frame beam end plate and Vierendeel girder is welded to connect；The end of active beam link end plate and active beam link is welded to connect；Vierendeel girder
End plate is connected with active beam link end plate by high-strength bolt；The outermost row of high-strength bolt must be located on the outside of the edge of a wing of active beam link；
Outer stiffener is set between the edge of a wing and active beam link end plate.
As a kind of optimization, it is based on above-mentioned technical characteristic, the back absolute altitude of active beam link and the back elevation difference of Vierendeel girder
Not less than 150 millimeters.I.e. the throw-off distances of active beam link and upper floor are not less than 150 millimeters.Active beam link and concrete building
Plate disengagement is that active beam link is replaced for convenience, while not influencing flooring use.
In above-mentioned technical proposal, the connection of active beam link end plate and frame beam end plate meets bearing capacity and rigidly connected wants
It asks.High-strength bolt undertakes whole shearings of junction, moment of flexure, axle power, and end plate and connection meet active beam link total cross-section and enter modeling
Property when keep elasticity ability.The size calculating of each component can be obtained according to Practical Project load and existing specification, formula.
The outermost row of high-strength bolt must be located on the outside of the edge of a wing of active beam link, help to improve the bending resistance carrying of connection in this way
Power realizes the weak component of strong ties.Outer stiffener is arranged between the active beam link edge of a wing and active beam link end plate can effectively reduce energy consumption
The deformation of beam section end plate, to improve the rigidity of end plate connection.
The art of this patent can restore the design concept of structure based on replaceable damage member, function, propose a kind of replaceable
The connecting node of active beam link, to realize the possibility repaired after shake and convenience.The present invention compared with the prior art, has as follows
Advantages and beneficial effects：
（1）The present invention proposes that a kind of connecting node of replaceable eccentrically braces structure active beam link, active beam link are easy to after shake
Dismounting and change realizes recoverable possibility and convenience after shake, and does not influence flooring and use function；
（2）Have the coupling stiffness essentially identical with traditional active beam link, does not influence overall structure rigidity；
（3）The connection of active beam link end plate and frame beam end plate can meet the detailing requiments of the weak active beam link of strong ties, not influence
The energy-dissipating and shock-absorbing effect of active beam link；
（4）High-strength bolt connecting structure is simple, and power transmission is reliable, undertakes all shearings of junction, moment of flexure, axle power.
