With the Development of Unbonded Post-tensioning Technology, architectural the world able to give full reign to their creativity - designing structures previously impossible to achieve. They can give column-free spaces - with which to enthrall and delight their audiences.
Advantages and Benefits :
- Post-tensioning (PT) frequently solves design and construction challenges that other construction methods simply cannot. Some key advantages include:
- Thinner concrete member sizes; reduction in concrete consumption up to 25%.
- Rebar in floor elements is reduced by 50% to 60%
- Decreased dead load reduces rebar and concrete in columns and foundations
- Longer spans and fewer columns give greater flexibility in floor layouts and better lighting in parking garages
- Reduced floor height also results in energy savings, especially for office buildings
- Improved seismic behavior
- Reduced deflection and vibration
- Improved crack control and waterproofing properties.
- Lower overall maintenance and life cycle costs of the structure
- Faster construction cycle due to early removal of shuttering.
