PTI Anchorage Zone Design
Post-tensioning of concrete requires the introduction of large, concentrated tendon forces into structures. To appreciate the magnitude of these forces, consider a typical bridge tendon with 19-152 mm (0.6 in.) strands. The jacking force for such a tendon may reach close to 4,000 kN (900 kips). This is equivalent to the weight of twelve HS 20-44 trucks Often several long tendons are anchored in…
