Description
Technical field
The present invention relates to a kind of steel to damp anti-fall girder apparatus.
Background technology
Can be seen that bridge structure frequency highest failure mode occurs from all previous earthquake is to fall beam to destroy.Fall beam destruction
Refer to that the superstructure of bridge departs from supporting its substructure, i.e., girder departs from from bridge pier or Abutment, causes girder to hang
Sky, fracture, or the phenomenon fallen.Produce the supporting length that the reason for beam destroys is between the superstructure of bridge and substructure
Degree is smaller, is not enough to tackle the excessive earthquake displacement of superstructure.But if setting bearing length according to earthquake analysis result,
Often cause substructure oversized, it is less economical.In bridge earthquake resistance field, the research for anti-fall girder apparatus is more,
But rigid member is limited to greatly, such as guy of twisted steel cable or rigidity chain.When rigid member plays a role, structure stress suddenly increases
Greatly, it can cause connecting portion that local failure occurs, in turn result in anti-fall girder apparatus failure.
The content of the invention
In view of this, it is an object of the invention to provide a kind of steel to damp anti-fall girder apparatus, use damped part to consume and
