Wall restorability plays a key effect.Under horizontal loads, when steel pipe concrete frame shear wall side tension one end by
When pressure, prestressing without bondn rod iron also cooperates.The elongation of tension side prestressing without bondn rod iron, prevents shear wall from continuing to become
Shape.When horizontal loading disappears, the tension unbonded prestressing tendon of still stretch section or elastoplasticity section has tendencies toward shrinkage, to reduce
Shear wall deformation.And when compression-side deformation is larger, after compression-side unbonded prestressing tendon prestressing force dissipates, it can still play one
Determine the effect of degree compression reinforcement, shear wall bearing capacity can be improved.The shear wall that the invention proposes has relative to common shear wall
Following advantage:

Steel strand wires remain to after the prestressing without bondn rod iron prestressing force in compression-side steel pipe concrete frame column dissipates as compression
Reinforcing bar continues to provide certain bearing capacity.And prestressed steel bar has preferable underrelaxation advantage compared with other presstressed reinforcing steels, enough mentions
For more reliable restoring force.
(2) steel pipe concrete frame column makes full use of the effect of restraint of concrete filled steel tube, is avoided that bottom foundation concrete
Conquassation too early, improves ductility of sheer wall；And steel pipe concrete frame column shares the more loads of wall, to a certain extent can
Shear wall's thickness is enough reduced, space utilization rate is improved.Frame is stronger to the constraint of concrete wall simultaneously, and wall is delayed to split
Seam is carried out.
(3) diagonal brace can be improved shear wall anti-seismic performance, and later period lateral rigidity is big.
Since shear wall is the core lateral resisting component of building structure, the shock resistance for improving shear wall, which just improves, finishes
