Subcase Information Entry
PRETENSION – Data Selection
Description
The PRETENSION command can be used in the Subcase Information section to select and activate a pretensioning bolt load.
Format
PRETENSION = option
Argument |
Options |
Description |
option |
< PSID > |
Pretensioning load set identification of a PTADD bulk data entry or, if a PTADD bulk data entry does not exist with this PSID, the set identification of PTFORCE, PTFORC1, PTADJST and PTADJS1 bulk data entry. |
| 1. | Only one PRETENSION entry can be defined for each subcase. |
| 2. | Combinations of PRETENSION and STATSUB(PRETENS) can be used to create more complex pretensioning sequences. |
| 3. | The rules for sequencing pretensioning subcases on the same pretension section are as follows: |
| a) | Pretensioning force (PTFORCE) can only be activated in the new or “fresh” pretensioning subcase for a given section. In other words, a subcase with PRETENSION pointing to PTFORCE cannot also include STATSUB(PRETENS) referencing a subcase that had already pretensioned this section. |
| b) | Pretensioning adjustment (PTADJST) may be activated in any of the pretensioning subcases for a given section. The effect of adjustment is cumulative relative to the pretensioning status reached in the respective previous subcase, as referenced by STATSUB(PRETENS). |
