Benefits of Post-Tensioning

BENEFITS OF POST-TENSIONING

WHY POST-TENSIONING?
Architects, Structural Engineers, General Contractors, Real Estate Developers, and Owners incorporate post-tensioning systems on their projects in order to achieve economy, efficiency, quicker construction and lower lifetime cost of the structure. Why? Because Post-Tensioning enhances concrete strength under both compressive and tensile stresses.

THE POST-TENSIONING PROCESS
Post-tensioning tendons are installed in a parabolic profile prior to placing the concrete and later stressed to a specified concrete strength. This process introduces both compressive forces in the concrete and stresses that counterbalance service loads. The benefits are substantial.

POST-TENSIONING: ADVANTAGES AND BENEFITS
Post-tensioning frequently solves design and construction challenges that other construction methods simply cannot. Some key advantages include:

MATERIAL SAVINGS

  • Thinner concrete member sizes; reduction in concrete is approximately 20%
  • Rebar in floor elements is reduced by 60% to 75%
  • Decreased dead load reduces rebar and concrete in columns and foundations
  • Reduction in building height decreases the cost of building cladding, vertical mechanical/service elements, and rebar and concrete in shear walls

QUICKER CONSTRUCTION

  • Potential pour cycle of 3-4 days
  • Reduced re-shoring requirements
  • Coordination with embeds and MEP openings

INCREASED PERFORMANCE

  • Improved seismic behavior
  • Reduced deflection and vibration
  • Improved crack control and waterproofing properties—especially beneficial for parking garages and balconies
  • Longer spans and fewer columns give greater flexibility in floor layouts in office/residential buildings and better lighting in parking garages which enhances personal safety.

REDUCED LIFETIME COSTS

  • Lower overall maintenance and lifecycle costs of the structure
  • Reduced building height also results in energy savings, especially for office buildings
  • Potential LEED® credits for Green building design and construction
