is there any way to confirm and modify the Bend flexibility factors calculated by AutoPIPE?
Yes and No.
Open the model in AutoPIPE, select Tools> Model Input listing> check all sub reports ON and press OK button to create a complete Model Input Listing report. After the report is displayed, scroll down to the Bend sub report and noticed the flexibility values calculated by the program are displayed in a column called Flexibility (k) for each bend point in the model:
1. Open the model input grids, select the Bend tab to change the bend flexibility values as needed:
2. Open Bend dialog and change the bend flexibility values as needed:
Bentley apologizes for the inconvenience, but at this time (AutoPIPE CONNECT 11.xx and lower) does not have the ability to view or modify the flexibility factor for a Tee type connection. According to some piping codes, B31.1 and B31.3, APPENDIX D, for most tee configurations the flexibility factor = 1.0 (please review the code).
Workaround, apply a user defined SIF at the TEE that takes into consideration a user defined flexibility factor for a Tee.
