Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: combinations Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version May 2015 09.06.02.06 Problem: Are predefined stress category maximums [i.e. (LONG), (Sus), (exp), (0cc), (hoop) ] calculated across all analysis set regardless of load cases turned ON / OFF in any one analysis set in an AutoPIPE model? Answer: The short answer is, YES. It is based on all load cases configured in the model. However, there is a way to force the program to utilize a specific load case for calculating the predefined stress category maximums [i.e. (long) ] for each analysis set. Please see the NOTES written on the following AutoPIPE help section: Help > Contents> Search Tab> enter " Case/Combination List (Standard)" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information. Note: A. To become more comfortable with user combinations, create example model(s) with one or more analysis sets with one or more "Number of operating load conditions" in each analysis set. Review the results from the different model s to understand specific user combinations. May need to create a user combination with only 1 load case to see what results are being used by the program. Example, code Combination name = long, see image below: B. If pressure extension analysis is turned on, and the result model option "Include axial, Pcase in Sus" is also turned on, then the forces and moments from pressure case shall be incorporated while calculating sustained stress.
