Post-Tensioning in Buildings
The use of Post-Tensioning in buildings offers numerous advantages and is increasingly used worldwide. SF-MGC uses the Bonded Post-Tensioning System which is the most commonly used PT System.
Advantages
- Provides longer spans, which reduces structural floor depths, resulting in larger column-free areas
- Thinner concrete sections
- Stiffer walls to resist lateral loads
- Stiffer foundations to resist the effects of shrinking and swelling soils
- Simpler stripping of formwork
- Fast construction cycles are envisaged
- Positive deflection control
- Improved constructability
- More architectural freedom
- Flexibility in subdivision of commercial and office floors
- Less material handling on site and storage
- Less labour on site
- Less environmental impact as reduced concrete and steel volumes are required
Post-Tensioning vs. Reinforced Concrete
Simple, Economical, Efficient, Fast Track Construction
-
RC DESIGN
Relatively low tensile strength and ductility are counteracted.
-
PT SLAB DESIGN
Thinner slabs that will result in more free height and height saving.
-
Result
Thinner slabs that will result in more free height and height saving.
HEIGHT SAVING
Savings in quantity of concrete and finished materials
THINNER SLAB
Absence of conventional reinforcement, absence of costly internal joint
Cost & time saved in casting large areas
Less labor & site congestion
Cost saving, less material handling, reduce of labor & site congestion.
YTL Residence
Larger column free spaces achieved with thinner slabs and less concrete volume.
Flat Slabs
Flat Slabs (no beams required) result in more free height and height saving.
