Benefits Of Choosing Post-Tensioning In Building Projects

In Building Projects

Most structural engineers and architects are aware of the advantages of post-tensioned concrete, which include 
the ability to use thinner members, longer spans, lower deflections, and lower prices. These advantages are 
well known, but did you know that when compared to other methods of construction, post-tensioned concrete 
provides a more sustainable design solution? This article examines six "unexpected" advantages of post-
tensioning in building construction.
Unexpected Benefits Of Choosing Post-Tensioning 
In Building Projects
● cost-savings
● construction with quickness
● less steel is used
● formwork and reshoring for the slab can be removed earlier
● follow-on trades can begin early
● sag and vibration on the floor have been reduced
● space and form flexibility in architecture
● building foundations with strength and flexibility
Cost-Saving
When compared to traditional reinforced concrete construction, most of 
us are aware that post-tensioning saves money in terms of concrete and 
reinforcing steel quantities. The cascading cost savings that occur in 
several components of the total building cost may surprise people.
Construction With Quickness
Another advantage of post-tensioning is that it allows for faster 
construction. Construction of a floor can be done faster due to the 
reduced materials utilised and the simplicity of the formwork
Less Steel Is Used
Placing steel is one of the most time-consuming aspects of construction, 
and because PT designs lower the amount of steel required, slabs will be 
ready to pour sooner. Unlike traditional concrete slabs, which require 
about 5 to 7 lb./ft2 of steel, post-tensioned flat slabs only require 2 to 3 
lb./ft2.
Formwork And Reshoring For The 
Slab Can Be Removed Earlier
Once the concrete reaches a strength of 3000 psi, PT slabs are ready to 
be stressed. Stressing the tendons 2 to 3 days after the pour is extremely 
common. After the stressing is finished, the formwork can be stripped 
and transported to the next pour.
Sag And Vibration On The Floor Have 
Been Reduced
Increased occurrences of vibration and deflection can be caused by the 
construction of lighter and longer floor constructions. However, post-
tensioning the concrete results in two crucial properties that 
considerably reduce vibration and sag. For starters, the wires' profile 
within the concrete creates a load balancing effect.
Space And Form Flexibility In 
Architecture
To preserve their strength and serviceability, traditional concrete slabs 
must be a certain thickness. Post-tensioned concrete, on the other hand, 
allows you to produce thinner and longer slabs without sacrificing 
structural serviceability and strength.
Building Foundations With Strength 
And Flexibility
Mat foundations can benefit from post-tensioning, which has a number 
of advantages. The cost of the foundation system will be reduced when 
the depth of the foundation system is reduced.
