what is post tensioning
An architect’s dream, a delight for developers, and a great tool for builders, post-tensioning allows almost any shape of structure to be constructed while minimizing environmental impacts, construction time, materials, and costs.
Since its first applications, PT technology has advanced significantly, particularly in performance, quality assurance, and durability, especially in corrosion protection. At its most basic level, post-tensioning offers flexibility, reinforcement, and strength, sometimes even making seemingly impossible constructions achievable.
The use of post-tensioning allows thinner concrete sections, longer spans between supports, and better resistance to lateral loads, making it an effective alternative to traditional reinforcement methods.
In concrete structures, steel reinforcement (rebar) alone does not always provide the required flexibility, often leading to cracks. Post-tensioning solves this by introducing pre-stressed steel strands or bars within the concrete. Once tensioned, these strands apply compressive forces, enhancing the structure’s durability and performance. This method is widely used in bridges, buildings, and infrastructure projects where strength, efficiency, and longevity are crucial.
A valid alternative
Post-tensioning has the potential to impact sustainable construction significantly. As demonstrated in practical applications, post-tensioned buildings use about 20% less concrete and 25-40% less steel than traditional reinforced concrete structures.
This translates into thinner floor slabs, reduced overall building weight, and increased energy efficiency, as less space is needed for heating and cooling. The reduction in resource usage during initial construction and lower maintenance costs throughout the building’s lifecycle make post-tensioning an attractive alternative to traditional reinforced concrete.
Developers looking for cost advantages, structural efficiency, and sustainability should seriously consider post-tensioning as a smart and future-ready solution.
Post-Tensioning benefits
These benefits are general but are more specific to suspended slabs.
Long Span
Post-tensioning permits longer spans than conventional reinforced concrete. Large column-free floor area provide increased flexibility for internal planning and space utilization.
Thinner Slab
The additional stiffness achieved by Prestressing enables reduced slab thickness. Maximum ceiling zone is available for horizontal services.
Reduced Storey Height
Due to the minimal need for deep down strands and the reduced slab thickness, minimum storey height is achieved; leading therefore to a lower overall building height. In situations where the height of the building is limited, the reduced storey height allows additional storeys to be constructed within the building envelope. Alternatively, this can reduced the façade area, as well as the vertical runs of mechanical and electrical systems.
Fast Construction
Easy and simple shuttering, reduced reinforcement. easy casting and early stripping and redeployment of the formwork obviously result in very fast construction.
Flat Soffit
Two-way post tensioned flat slabs show no down strands, providing best flexibility for space partitioning and for the placing of services network (HVAC, electrical, sanitary, etc...).
Flexibility of Services
The simple concept of post tensioned slabs, the reduced amount of ordinary reinforcement and the flexibility in the positioning of openings and inserts for services. Little coordination is required between designers for this purpose, and late modifications can be implemented without prejudice to the initial structural and architectural design.
Crack Control
Post-tensioned floors in compression allow for easier control of cracking. If appropriate design criteria is applied, crack-free construction can be achieved. This is often exploited in car parks with concrete surfaces exposed to an aggressive environment.
With reduced cracking, better water tightness is achieved and the durability of the structure is improved.
Deflection Control
By varying the amount of post-tensioning, the designer is able to control deflection under service loads.
Flexibility of Layout
The design of post-tensioned slab can cope with irregular grids and tendons can easily be deflected horizontally to suit any layout’s geometry or to allow for openings in slabs.
Future Flexibility
The myth about the possible demolition of post-tensioned slabs are now dispelled. Knockout zones can be easily identified for future service penetrations. Tried methods are available to enable large openings to be formed subsequently in future alterations.
Lighter Structure
Post-tensioning enhances the efficiency of concrete sections and hence, saves considerably on the concrete volume. Slender slabs produce lighter overall structures which reduce on foundation size and cost.
Cost Saving
All the above advantages imply significant savings in the overall cost of the construction.
