Advantages of Post-Tensioning in building construction?

The advantages of post tensioning in building construction is significant in that new designs and structures can be built with a large reduction in the amount of concrete and reinforcing steel required.
Due to the reinforcement, thinner structural members are required as compared to non-prestressed concrete. This can result in lower overall building heights or higher ceilings and reduced foundation loads. ,

Structures can become more modern and aesthetically pleasing that harness the benefits of cast-in-place structures and can contain curved geometries, longer cantilevers and more slender members with larger spaces between their supports.

Post pensioned tensioning  is superior in structural integrity as compared to precast concrete construction because of continuous framing and tendon continuity.  Monolithic connections between slabs, beams, and columns that can eliminate troublesome joints between elements that require maintenance.

Profiled tendons that result in balanced gravity loads (typically a portion of dead load only), significantly reducing total deflection. Concrete with post tensioning has better crack control, which results from permanent compressive forces applied to the structure during prestressing.

Because of the overall reduction in building mass these structures are much more stable in zones of high seismicity.

As compared to steel, non-prestressed concrete and precast construction offer faster floor construction cycles, lower floor weight, lower floor-to-floor height, larger spans between columns and reduced foundations.

The high early-strength of post-tensioned concrete allows for faster floor construction cycles and the use of standard design details for post-tensioned elements, minimum congestion of prestressed and non-prestressed reinforcement, and earlier stripping of formwork after tendon stressing.
