Wound is concentrated among replaceable steel column component 2 and replaceable energy consumption coupling beam 7.And replaceable steel column component 2 uses segment design,
It is made of more replaceable steel columns 21, facilitates earthquake to replace one by one afterwards.The steel column 21 of damage is only needed to change after the earthquake i.e.
Repaired after can completing shake, be easy to shorten repair time, reduce maintenance cost.
According to some embodiments of the present invention, replaceable energy consumption coupling beam 7 is set at second connection Steel section member 3, it is replaceable
Energy consumption coupling beam 7 is connected Steel section member 3 with second and is connected.
Wherein, by being designed to the strength of materials, interface form and the sectional dimension of replaceable energy consumption coupling beam 7, it is made
Shearing strength is less than the shearing strength of the second connection Steel section member 3 and the shearing strength of replaceable energy consumption coupling beam 3 is less than top
The local bearing capacity of armored concrete cylinder 4, thus, it is possible to guide damage after shake to focus primarily upon replaceable energy consumption coupling beam 7,
Do not destroyed so as to be conducive to the connection Steel section member 3 of protection second and upper reinforcement concrete barrel 4, reduce maintenance cost.
Replaceable energy consumption coupling beam 7 and second is connected between connecting Steel section member 3 by bolt 5, after the earthquake can be square
Just the replaceable energy consumption coupling beam 7 for displacing damage, can realize the quick reparation after shake.
According to some embodiments of the present invention, replaceable steel column component 2 and replaceable energy consumption coupling beam 7 can use low strong
Steel, so that ensure that the replaceable steel column component 2 in bottom and replaceable energy consumption coupling beam 7 have preferable energy-dissipating property, and can
Avoid the brittle breaks such as steel plate tear.
Referring to figs. 1 to Fig. 3, according to some embodiments of the present invention, replaceable steel column component 2 is connected shaped steel with first respectively
Component 1 is connected with the second connection Steel section member 3 by bolt 5.In other words, replaceable steel column component 2 is connected shaped steel structure with first
Part 1 is connected by bolt 5, and replaceable steel column component 2 is connected Steel section member 3 with second and is connected by bolt 5.
Steel column 21 is in and to arrangement, is connected between adjacent steel column 21 using bolt 5, so that moment of flexure can be born by forming one
With the entirety of shearing.Connected between connection Steel section member and the replaceable steel column component 2 of bottom using bolt 5.Divide due to using
Section assembled design, if the experience earthquake of replaceable steel column component 2 damages, the more change of current of the replaceable steel column component 2
Cheng Wei：(1) all bolts 5 with first replaceable steel column 21 are removed；(2) the replaceable steel column 21 of first damage is replaced；
(3) remaining all steel columns 21 are replaced one by one according to same way.
Further, the first connection Steel section member 1 with presetting screw hole (in figure not at the interface of replaceable steel column component 2
Show) so that the first connection Steel section member 1 is bolted with replaceable steel column component 2；Second connection Steel section member 3 with it is replaceable
Screw hole is preset at the interface of steel column component 2 so that the second connection Steel section member 3 is bolted with replaceable steel column component 2.By
This, easy to the installation and removal of replaceable steel column component 2.

Further, can include with reference to Fig. 1 and Fig. 3, the first ribbed stiffener 211：Transverse stiffener 2111 and longitudinal direction add
Strength rib 2112.(for example, left and right directions shown in Fig. 1) extends transverse stiffener 2111 in the horizontal direction；Longitudinal stiffener
2112 are connected with transverse stiffener 2111, and longitudinal stiffener 2112 can be vertically (for example, upper shown in Fig. 1
Lower direction) extension.Be conducive to improve the rigidity of replaceable steel column component 2 by the first ribbed stiffener 211, ensure replaceable steel column 21
Local buckling does not occur.
According to some embodiments of the present invention, the first connection Steel section member 1 and/or second connects Steel section member 3 and is equipped with
The second ribbed stiffener of multiple tracks, per pass (or each) described second ribbed stiffener can be configured to linear type (or T-shaped etc.).Thus,
The second ribbed stiffener of multiple tracks is set on Steel section member 3 by being connected in the first connection Steel section member 1 and/or second, is advantageously ensured that
The destruction such as surrender, local buckling does not occur in earthquake for it so that connection Steel section member has larger rigidity and intensity.
Referring to figs. 1 to Fig. 3, according to some embodiments of the present invention, the first connection Steel section member 1 and second connects shaped steel structure
The section form of part 3 can be I-shaped or box.The section form of multiple steel columns 21 can be I-shaped or box.Connecting-type
Steel member and steel column 21 can use but be not limited to I-shaped or box cross-section form.
Steel section member is connected using the steel of intensity higher and the sectional dimension of bigger, and is provided with multiple tracks ribbed stiffener.
So that connection Steel section member has larger rigidity and intensity, it is broken to ensure that surrender, local buckling etc. do not occur in earthquake for it
It is bad.
According to some embodiments of the present invention, longitudinal reinforcement (not shown) is equipped with upper reinforcement concrete barrel 4,
