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
