The unbonded prestressing tendon is piecewise dam axis, and the automatic control dissipative cell is arranged at unbonded prestressing tendon and turned
To place, the end of unbonded prestressing tendon is connected with presstressed reinforcing steel anchored end, and the stirrup surrounds beam upper longitudinal bar and beam bottom
Vertical muscle is set, and stirrup is welded with spacer bar, and spacer bar is welded with automatic control dissipative cell；
The automatic control dissipative cell includes top turner bar, deformation box Outboard Sections, deformation box main body, deformation box inside portion
Point, side turner bar, bearing plate and side shield, the deformation box main body both sides are respectively on the inside of deformation box Outboard Sections and deformation box
Part, deformation box main body and pressure-bearing plate weld, are provided with side turner bar, deformation box main body and top between deformation box main body and bearing plate
Turner bar is connected, and lower edge and the bearing plate of the side shield pass through building structure gemel connection.
Preferably, the stirrup encrypts setting at automatic control dissipative cell.
Preferably, the top turner bar and side turner bar are made using rod iron, the bearing plate is made using steel plate, institute
It is that iron member and carbon fiber board, carbon cloth are gluing into (deformation box adds the purpose of carbon fibre material to state deformation box main body
It is to improve intensity, mitigate weight), the side shield is made using carbon fiber board.
Preferably, the top turner bar and side turner bar are respectively semicircle and circular cylinder steel member, and by building
Building structure glue is connected with other components.
Beneficial effect：The present invention is pre- in the soap-free emulsion polymeization that fold-line-shaped prestressing without bondn turning point is disposed with automatic control dissipative cell
Prestressed concrete framework, automatic control dissipative cell is in a dormant state under frequently occurred earthquake and middle shake；Automatic control consumes under rarely occurred earthquake
Can element bearing capacity reach threshold value, then start and deform, cause Vierendeel girder anti-bending bearing capacity reduce and make beam prior to
There is plastic hinge in post.Framework is under earthquake by the rotation of the plastic hinge of beam-ends come the inputting seismic energy that dissipates, formation beam hinge machine
System.I.e. under rarely occurred earthquake, manual control is consumed energy with beam, and to ensure that the damage of post is lighter, this meets conceptual Design of Earthquake Resistance.By
Limit stress is much smaller than in presstressed reinforcing steel stress after this Vierendeel girder formation plastic hinge, it is ensured that presstressed reinforcing steel plastic hinge occurs in beam
It is follow-up it is continuous play a role, so as to extend the length of the elastic-plastic phase of Constrained surrender, form ductile frame.
