With certain restorability.In seismic energy input, reinforced concrete wall panel starts to play and make as one of anti-vibration defense lines
The appearance in concrete wall crack is delayed with, steel pipe concrete frame and built-in steel plate, the prestressing force of application can be certain
The recoverable force for making wall in degree effectively reduces integrally-built displacement, improves concrete panel vertical bearing capacity and extensive
Multiple power.With the increase of input energy, concrete wall cracking, the close surrender of steel pipe concrete frame, steel pipe concrete frame
The displacement of wall still can be constrained also still in elasticity in the unbonded prestressing tendon of interior setting.Unbonded prestressing tendon and steel
Have between the built-in steel plate combined shear wall of pipe concrete frame it is good work together performance, unbonded prestressing tendon wall by
Elasticity is kept during power, the prestressing force of application can constrain the deformation of wall, and make wall that there is restorability, concrete wall
Relative shear sliding is substantially reduced, cracking dispersion, and bearing capacity, ductility and energy dissipation capacity are more mixed than normal concrete shear wall and fashioned iron
Solidifying soil shear wall is significantly improved, and later period anti-seismic performance is relatively stable, and prestressing without bondn post-tensioning is easy for construction, can be used for high level
Or in large complicated tier building.
Core lateral resisting component of the shear wall as building structure, improves the shock resistance of shear wall, also just improves
The shock resistance and restoring force of structure entirety, when building meet with violent earthquake when, can reduce its earthquake, after shake can part it is extensive
It is multiple.
