POST-

TENSIONING

SYSTEM

The use of post-tensioning system in building offers numerous advantages such as economic savings, minimised floor-to-floor heights, increased column-free space, minimised foundations, in seismic areas, reduced weight and lateral load resisting systems, simplified slab design and construction etc.

Advantages of post-tensioning system

Reduction of total labor costs for constructionmore than twice

Shallow structural depth Bigger column-free spans Less steel and concrete consumption on 50% Reduction in foundation loads in 2-3 times Better deflection control Better crack control

Transverse components and panel forces resulting from post-tensioning

Principle of the load-balancing method
