Post Tensioning Systems in a Parking Structure

Strengthening with Post-Tensioning Systems
Post-tensioning systems help control deflection, are corrosion and fire resistant, and reduce concrete mass and building costs. External post-tensioning consists of prestressing tendons externally attached to the structural element at anchor points, typically located at member ends. Uplift forces are introduced to the member at specific locations along its span. By controlling the tendon’s profile along the member, the desired level of capacity and serviceability improvement is achieved.

Internal post-tensioning systems, on the other hand, are installed within the member; therefore, the structural element itself provides the required protection to increase durability and fire resistance. After stressing, the tendons may be grouted to achieve a bonded system.

Features and Benefits:
  • Control Deflection
  • Corrosion Resistant
  • Fire Resistant
  • Applicable for Substantial Load Capacity Improvement
