POST-TENSIONED CONCRETE ENGINEERING

POST-TENSIONED CONCRETE TECHNOLOGY

IN WHICH BUILDINGS IS IT USED?

  • New generation damage-controlled precast industrial buildings (PRESSS)
  • Building slabs which have very large spans and loadings
  • Bridges
  • Slabs-on-ground

POST-TENSIONED CONCRETE TECHNOLOGY

WHAT ARE ITS SUPERIORITIES?

Post-tensioned concrete is ‘balancing’ the internal tensile stresses in concrete -which has negligible tensile strength- by way of tensioning high strength tendons (or bars) and releasing them to apply compressive stress to concrete tendons.

Post tensioning strands are more than 3 times stronger than conventional mild construction rebars. In addition to that, since it is jacked, it is in fact a ‘live’ load which balances the gravitational loads on the structure. This enables post-tensioned concrete to span very large distances with very large live loads.

Post-tensioned concrete, because of these unique aspects, is not only superior but also unrivaled.

POST-TENSIONED CONCRETE TECHNOLOGY

WHY DOES IT REQUIRE EXPERTISE?

Post-tensioning is a balancing and live loading that acts on the structure. This loading which is in complicated profile and has hyperstatic effects, should be analyzed and designed very carefully.

This live loading on the structure also is not constant throughout the structure’s life; it undergoes short term and long term losses. The stresses on the tendons change according to time. And this requires expertise on understanding the behaviour of post-tensioning; because these changes affect the structure.

Another unique aspect of post-tensioning technology is the anchors. Especially in unbonded post-tensioned concrete, correct analysis and design of the anchorages are crucial, because any failure of the anchorages means failure of the entire system.

For these reasons design of post-tensioned concrete structures should be done by engineers who have experience in post-tensioned concrete.
