Power concrete frame.
Background technology
Existing research generally suggests that frame structure includes that unbonded prestressed reinforced concrete frame structure uses hybrid energy dissipation
Mechanism carries out Aseismic Design, and beam hinge energy consumption mechanism is better than mixed energy dissipation mechanisms.Because beam cuts with scissors energy consumption mechanism and mainly relies on
The plastic hinge of beam-ends removes dissipation seismic energy, not high to the Ductility Requirement of styletable, the curvature that beam hinge requires critical cross-section
Ductility increases few；Mixed energy dissipation mechanisms are that beam hinge and column is relied on to cut with scissors dissipation seismic energy simultaneously, so the section to styletable is prolonged
Property has higher requirement.
Invention content
The purpose of the present invention is overcoming energy dissipation capacity existing for unbonded prestressed concrete structure poor, provide
A kind of automatic control energy consumption unbonded prestressed reinforced concrete frame meeting conceptual Design of Earthquake Resistance theory, the frame system have been played without viscous
Tie prestressed reinforced concrete construction cracking resistance deformation performance it is good, from heavy and light and easy construction the advantages of, promoted the use without viscous for earthquake territory
Knot prestressed concrete frame has started a new way.
The technical solution adopted by the present invention is：A kind of unbonded prestressed reinforced concrete frame to be consumed energy using anchorage bearing,
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 present invention is disposed with the nothing of automatic control dissipative cell at curved shape unbonded prestressing tendon anchorage bearing
Binding prestress concrete frame, automatic control dissipative cell is in a dormant state under frequently occurred earthquake and middle shake；Under rarely occurred earthquake
Automatic control dissipative cell bearing capacity reaches threshold value, then starts and deforms, and the anti-bending bearing capacity of Vierendeel girder is caused to reduce and make
There is plastic hinge prior to column in beam.Frame is under earthquake by the rotation of the plastic hinge of beam-ends come the inputting seismic energy that dissipates, formation
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 seismic Concept
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 goes out in beam
Existing plastic hinge it is subsequent it is continuous play a role, to extend Constrained surrender elastic-plastic phase length, form ductile frame.
