Sweeping beam tendons into the slab
Occassionally, the field will encounter a condition where the post-tensioned beam’s CGS (center of gravity of steel) requires several PT beams be installed in the slab. In other words, some PT anchors will not be installed within the web of … Continue reading
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
Kink in a Tendon
On rare occasions, the installer will unroll a tendon that looks like this… WHAT WILL HAPPEN? During the stressing operation, this tendon will probably break due to the eccentric force at the anchorage. Chances are that this tendon would break … Continue reading
