By nkhosa, on March 10th, 2011% 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 of Strand (usually Low-Lax) Ultimate Strength of Strand (usually 270 ksi) Modulus of Elasticity of . . . → Read More: Post Tension Friction-Loss Calculations
