Advantages of Post Tensioning

ADVANTAGES / BENEFIS OF POST TENSIONING

A. SAVINGS IN MATERIAL
  • Reduction in concrete structural element dimensions (slabs, beams, columns – 20 to 25%)
  • Reduction in reinforcement quantities (55 to 60%)
  • Reduced self weight (dead load) reduces reinforcement and concrete in slabs, columns and foundations
  • Reduction in total building height (1 floor gained each 20 floors)
B. SAVINGS DURING CONSTRUCTION
  • Pour (concreting) cycle of 6 to 7 days (Quicker Construction)
  • Reduction in number of formwork (shuttering) sets
  • Quick rotation of formwork sets (45 to 50%)
  • Earlier removal of formworks
  • Reduction in concrete reinforcement, formwork quantities
  • Reduction in manpower requirements due to reduction in material requirement
C. STRUCTURAL PERFORMANCE
  • Better waterproofing and improved crack control
  • High deflection limitation due to concrete shrinkage and creep
  • Improvement of durability and concrete behavior
  • Increase in free space availability, greater flexibility in floor layouts, and more architectural opportunities
D. LONG TERM PERFORMANCE ADVANTAGES
  • Reduction of construction volumes and energy needed for heating, cooling, living spaces
  • Overall maintenance costs of structure
  • LEED & Green building design and construction
