Comments
- PTADJST can be referred by PTADD or by the PRETENSION command in the subcase directly.
- 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).
- 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.
