Problem:
What does "Remove Lift-off Supports" mean on AutoPIPE's Analysis sets dialog?
Solution:
To be able to calculate the sustained stress when in cold condition, or when in hot condition is a code requirement.
From AutoPIPE help:
Enable this feature for non-linear analysis sets to remove supports that lift off during hot sustained.
Only enabled for ASME B31.3 2014 and later editions
AutoPIPE's non-code combination GrP1..GrPn would be both hot and cold sustained combination:
If supports, that would otherwise be physically present, are theoretically removed before performing an analysis , it would be considered HOT sustained...
if supports are all left in place regardless of lift-off reported by analysis, it would be COLD sustained...
