The utility model solves the operation principle that its technical problem is used：
The utility model is arranged at the bean column node annex of steel-frame structure, and component damage control fuse uses ordinary steel
Or Low Yield Point Steel processing and fabricating, with preferable ductility.The principle of Damage Coutrol is as follows：（1）When building is by more than expection
Earthquake when, the utility model is surrendered in main body frame first, prevent associated components internal force rapid growth, make body frame
Frame keeps elastic stage, and provides certain energy dissipation capacity.（2）The increase being plastically deformed with fuse, flange of beam compression-side
Beam section bearing capacity where flexing, fuse occur for Damage Coutrol fuse reaches peak value, and the bearing capacity is just below component hair
Internal force needed for raw damage.（3）Increase with the continuation of the deformation of member, rear bearing capacity is bent in song with general Damage Coutrol fuse
Rapid reduction is different, and section bearing capacity where can maintaining fuse based on the bent fuse for bending control of appropriateness is basicly stable, favorably
In raising Structural Energy Dissipation ability and control structure deformation.（4）The bent principle in the wrong of appropriateness of the present utility model is embodied in, and works as Damage Coutrol
When fuse flexing is reached to a certain degree, song bends constraint cover plate and bent constraint bolt of bending enters working condition, and limitation fuse is bent
The excessive development of song deformation, makes Damage Coutrol fuse obtain bearing capacity after stable song is bent.（5）After earthquake terminates, not in
In the case of the use of disconnected building, quickly impaired Damage Coutrol fuse can be changed one by one.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
