Unbonded prestressed concrete structure cracking resistance deformation performance is good, from heavy and light and easy construction the advantages of, promoted the use for earthquake territory
Unbonded prestressed reinforced concrete frame structure has started a new way.
The technical solution adopted in the utility model is：A kind of unbonded prestressed concrete frame to be consumed energy using anchorage bearing
Frame, including ordinary reinforced concrete column and automatic control energy consumption no-bonding pre-stress concrete beam；
The ordinary reinforced concrete column does not set presstressed reinforcing steel, and the automatic control energy consumption no-bonding pre-stress concrete beam includes
Muscle and presstressed reinforcing steel anchoring are indulged in automatic control dissipative cell, spacer bar, stirrup, unbonded prestressing tendon, beam upper reinforcement, beam lower part
End；The unbonded prestressing tendon arranges that the automatic control dissipative cell is set to unbonded prestressing tendon anchoring branch for curved shape
At seat, the end of unbonded prestressing tendon is connect with presstressed reinforcing steel anchored end, and the stirrup surrounds beam upper longitudinal bar and beam lower part
Vertical muscle setting, stirrup are welded with spacer bar, and automatic control dissipative cell is welded with spacer bar；
The automatic control dissipative cell includes in bearing plate, side shield, deformation box main body, deformation box exterior portion and deformation box
Side section, the deformation box main body both sides are deformation box exterior portion and deformation box inboard portion, deform box main body and side shield
Lower edge by building structure glue connection, top edge and the bearing plate of the side shield pass through building structure glue connection.
It is arranged preferably, the stirrup is encrypted in automatic control dissipative links end.
Preferably, the bearing plate is steel plate, the deformation box main body is carbon fiber board component and carbon cloth gluing
Into (deformation box is to improve intensity, mitigation weight using the purpose of carbon fibre material), the side shield is made of plank.
Advantageous effect：The utility model is disposed with automatic control dissipative cell at curved shape unbonded prestressing tendon anchorage bearing
Unbonded prestressed reinforced concrete frame, automatic control dissipative cell is in a dormant state under frequently occurred earthquake and middle shake；Meet ground rare
The lower automatic control dissipative cell bearing capacity of shake reaches threshold value, then starts and deforms, the anti-bending bearing capacity of Vierendeel girder is caused to reduce
And beam is made plastic hinge occur prior to column.Frame under earthquake by the rotation of the plastic hinge of beam-ends come the inputting seismic energy that dissipates,
Form beam hinge.I.e. under rarely occurred earthquake, artificial control is consumed energy with beam, and the damage to ensure column is lighter, this meets antidetonation
Conceptual design.Presstressed reinforcing steel stress is much smaller than limit stress after forming plastic hinge due to this Vierendeel girder, it is ensured that presstressed reinforcing steel exists
Beam occur plastic hinge it is subsequent it is continuous play a role, to extend Constrained surrender elastic-plastic phase length, form ductile frame.
