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 reducing 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.
Utility model content
A kind of accentric support steel construction for being reliable, easy to replacement the purpose of this utility model is to provide a kind of power transmission can be more
Change the connecting node of active beam link.Which solve conventional steel frame-eccentrically braces structure active beam link connecting nodes cannot achieve
Problem can be repaired after shake, and does not reduce its energy consumption effect.
The utility model is technical solution are as follows: active beam link is located between the end of two accentric supports；Vierendeel girder and consumption
It can beam section horizontal connection；The back absolute altitude of active beam link is lower than the back absolute altitude of Vierendeel girder, makes the floor at active beam link and top
It disengages；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；Frame
End plate of setting a roof beam in place is connected with active beam link end plate by high-strength bolt；The most outlet of high-strength bolt must be located at outside the edge of a wing of active beam link
Side；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 the whole shearings, moment of flexure, axle power of junction, and end plate and connection meet active beam link total cross-section and enter modeling
Property when keep elasticity ability.The size of each component, which calculates, to be obtained according to Practical Project load and existing specification, formula.
The most outlet 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, with realize shake after repair a possibility that and convenience.The utility model compared with the prior art, has
Following advantages and beneficial effects:
(1) the utility model proposes a kind of connecting node of replaceable eccentrically braces structure active beam link, active beam link exists
It is readily disassembled replacement after shake, realizes recoverable possibility and convenience after shake, and does not influence flooring and uses function；
(2) have the coupling stiffness essentially identical with traditional active beam link, do not influence overall structure rigidity；
(3) 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, no
Influence the energy-dissipating and shock-absorbing effect of active beam link；
