Description
Technical field
The present invention relates to a kind of power consumption coupled column in earthquake with bidirectional oriented function of collapsing, which is normally using shape
Strength build requirement and requirement for bearing capacity is met in state, has enough ductility and energy-dissipating property under geological process.Work as building
When being likely to occur collapse because there is serious earthquake, consume energy directional rotating ability of the coupled column using orientable revolving member
Building is made to collapse to anticipated orientation, it is to avoid to build the destruction for collapsing and causing Adjacent Buildings to unfavorable direction.The invention belongs to
Technical field of preventing and reducing natural disasters in civil engineering.
Background technology
China's multi-rise building is increasing at present, and related structure stress feature and anti-seismic performance requirement are also gradually tight
Lattice.With the continuous densification of multi-rise building, collapsing for geological process next one building is possible to meeting to Adjacent Buildings
There is the destruction that effect of impact or aggravation are nearby built, in the earthquake disaster for actually occurring, a lot of buildings are all due to adjacent
Collapsing for building is clashed into and there occurs destruction.Additionally, in the important engineering structure such as nuclear power, accessory structure is apart from agent structure
Relatively near, if accessory structure collapses to main direction, may cause agent structure that the security incidents such as nuclear leakage occur, produce greatly
Secondary disaster, it should strictly protect.Therefore, building structure how is avoided to collapse to unfavorable direction or make structure fall with orientation
This problem for function of collapsing has become the focus of urgent need to resolve in intensive multi-rise building thing Aseismic Design.Ask for this
Topic, the present invention propose a kind of power consumption coupled column with bidirectional oriented function of collapsing, and the cylinder by multiple segregant posts and is determined
Constitute to component.Multiple segregant posts are placed by certain spacing, arrange sub- post connector and can be directed in the gap of each sub- post
Revolving member.Significant points in building structure are installed coupled column or replace existing common load-bearing pillar with coupled column, can
To improve shock resistance of the building in earthquake, and also can occur according to the direction of regulation when guaranteeing that building structure collapses
Collapse, to reduce impact damage of the building to Adjacent Buildings that collapse.
Content of the invention
Collapse the mutual impact damage of phase this situation to improve adjacent multilayer structure thing, make building collapse
When can according to regulation direction collapse, the present invention propose a kind of power consumption coupled column with bidirectional oriented function of collapsing, the group
The features such as zygostyle has Directional Collapse, power consumption property is strong, will occur promote building by regulation when destruction is collapsed in building
Collapse in direction, it is to avoid build the destruction for collapsing and causing Adjacent Buildings to unfavorable direction.

Degree sum.
The function of the present invention is as follows：
Sub- post connector and orientable revolving member are set in each segregant post gap, and in earthquake, sub- post turns orientable
Shearing and the moment of flexure of orientation will be produced under the guiding of dynamic component, building is occurred according to the direction of regulation when finally destroying
Collapse, it is to avoid the effect of impact to adjacent buildings, so as to reduce the injures and deaths in earthquake.
Coupled column each deforms to consume the energy in earthquake under geological process by each sub- post using multiple segregant posts
Amount, so that reduce the destruction of building.
The friction shim rotated at break-in of sub- post connector and orientable revolving member adopts the material of high frictional force such as
Brass, zinc etc. make, and can consume the energy in earthquake by the friction of friction shim, reach the mesh of damping during relative rotation
's.
Certain thickness power consumption rubber blanket is filled at the occlusion of sub- post connector, orientation member is had in other direction
