Post Tension Friction-Loss Calculations
The friction-loss calculations are important submittals for post-tensioning tendons. The calculations determine what the tendon’s final force is after short-term and long-term friction losses. The key input parameters for “Long-Term Losses” are as follows: Post-Tensioning System (Unbonded or Bonded) Type … Continue reading
VIDEO: Field Friction Test for Post Tension Tendons
This educational video from AMSYSCO, Inc. shows the process for determining the Friction Coefficients. Post Tensioning Institute (definitions): Friction Loss: the loss of stress (force) in a prestressing tendon resulting from friction created between the strand and sheathing during stressing. … Continue reading
