Comments

  1. PTADJST can be referred by PTADD or by the PRETENSION command in the subcase directly.
  2. Pretensioning adjustment shortens the pretensioned bolt by "removing" the set amount of material. This represents the effect of turning the nut by a set distance (number of turns).
  3. Pretensioning adjustment using PTADJST can also be used to define additional shortening to a pre-tensioned section. Therefore, when adjustment is applied to a section that has already been pre-tensioned, the final effect will be a sum of the status reached in the preceding pre-tensioning subcase plus the amount of adjustment through PTADJST.
