For that reason, elongations have always been used as a way to assess the post-tensioned forces within the tendons because the tendon force is directly proportional to the elongation through a known equation. The equation for calculating tendon elongations is shown as follows: PL = AE When jacking to 202.5 ksi, and using a strand nominal area of 0.153 in January 15, 2014. ]4cr,d_g+Y[kcEq
