See support output for details --------------------------- OK --------------------------- what should I do? Solution This warning occurs when pipe moves in a +ve upward direction off of the support (AKA lift-off has occurred). Another words in the Forces and Moments report, for any combination where the total vertical +ve force is greater than or equal to the Gravity (-ve) force, lift-off has occurred. a. Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Bentley AutoPIPE> Frequently Asked Questions> FAQ document> Question 22: When I see the V-stop Lift-off warning message after the static analysis how can I find out where the lift-off is occurring? b. In addition, Please see the following AutoPIPE help section: Help > Contents> Search Tab> enter "VStop LiftOff" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information Most programs (at least the popular ones like CAESARII and AutoPIPE) evaluate sustained stress under the cold condition. AutoPIPE correctly considers the support lift-off effect on expansion stress by evaluating two real operating cases, Hot (i.e. GR+T1) - Cold (i.e GR). When a net +ve up movement is detected a warning for support lift-off displayed. The recommended practice at least by one B31 committee member is to use cold sustained stress (one that ignores support lift-off) when the lift-off is less than about 1/4" as it would be too conservative otherwise and sustained displacements of that order would not constitute failure. The logic of this is that this 1/4" displacement is self limiting like the expansion case and the system would settle to this No-lift-off configuration before it fails. For large support lift-off, many but not all, engineers tend to delete the supports that have the lift-off, and then rerun for hot sustained stress case. This is easy in AutoPIPE as you can list supports with lift-off using the results grid or support filter. Results Grid Method: On the Support Tab of the Results Grid, uncheck all load cases except combinations (i.e. GRT1, etc..) and double click on Global DY column to sort by displacement looking for any value >0.00. If your company procedure requires removal and re-analyze, delete these supports where lift off has occurred and rerun the analysis looking only at sustained stress. After the check, you can then undo this support deletion or save the model as another name if you wish. Support Filter method : Please see the following AutoPIPE help section: Help > Contents> Search Tab> enter "Show lift-off supports" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information. Most designers try to avoid large lift-off because of this issue and so they move the supports or replace with a spring hanger type support. Again, many companies have their own rules in dealing with support lift-off and therefore Bentley does not side with any approach. It is up to the user what to do when Lift-off occurs: a. Always use cold sustained and ignore lift-off b. Always remove uplifted supports and rerun for hot sustained c. Ignore lift-off if less than a certain tolerance, like 1/4" or 1/16". The ASME B31.3 piping code has a new alternate method (Appendix P) for evaluating operating stresses as well as expansion stresses. This may partially address the hot sustained issue as this sets an allowable for operating loads that include gravity, pressure and temperature. AutoPIPE evaluates these under the hot condition. In addition, it may be a tolerance issue. Check the displacement at the support for that case and see vertical displacement is greater than zero. If it is very small displacement like +0.001 inch or zero that means it is a tolerance issue. You may reduce the nonlinear iteration tolerances if you wish to have this support removed from the list of supports where lift off is occurring. In conclusion, Bentley cannot provide you with specific details on how to handle support lift-off. Your company should have standards set in place for such occurrences.

Applies To Product(s): AutoPIPE Version(s): ALL; Environment: N/A Area: Import Original Author: Bentley Technical Support Group Date Logged & Current Version July. 2017 11.00.00.22 Problem: Can OpenPlant Support Engineer (OPSE) export a support directly to AutoPIPE? Solution: At this time there is no direct workflow between AutoPIPE and OpenPlant Support Engineering (OPSE). OPSE is an application which will provide complex design and Modeling of Support for Piping, Structural, Electrical and HVAC Components in an OpenPLANT model environment. Typical workflows are: 1. OpenPlant Support Engineering can be used with referenced i-models from OpenPlant Modeler and structural tools such as ProStructures. 2. OpenPlant Support Engineering can also works in conjunction with OpenPlant Model Server in a component based workflow by referencing out piping components or work breakdown structure elements in order to begin work and then checking in support components upon completion to OpenPlant Model Server. These support objects can then appear in isometrics generated from OpenPlant Isometrics Manager. Once an OPSE support has become part of the OpenPlant model, it may be exported using the typical workflow interface between OpenPlant and AutoPIPE, or PXF file. AutoPIPE will be able to import the PXF file where any mapping changes can be made as needed. See Also Troubleshooting - Import AutoPlant / OpenPLANT PXF file Bentley AutoPIPE

Wiki Page: 16. Color Stress Plot appears to be wrong about a Tee in AutoPIPE, why?
Applies To Product(s): AutoPIPE Version(s): ALL; Environment: N/A Area: Graphics Original Author: Bentley Technical Support Group Date Logged & Current Version Aug. 2016 10.01.00.09 Problem: The color plot about a tee seems to be wrong, see image below for example: Why and how to fix it? Solution: Let us first look at the construction of the Tee based on segments, View> Show Options> Segments color plot: As one can see the tee is made up of 2 segments (ex. H and P). H segment = 1/2 the run of a tee and the branch of a tee P segment = 1/2 the run of a tee This modeling approach is OK and the stress values are calculated correctly. Note: check the Model Consistency report to see if any warnings are related to this issue. The following Warning was found: W726-7: Pipe diameter change without a reducer at following point(s) B06, F06, G06, H07 , P02 A better approach would be to model the entire run of a Tee with one segment and the tee branch with a separate segment. See the following WIKI page here to alter the modeling approach. See updated modeling approach segment color plot below: Now re-run the analysis and check the new color plot: Again the calculates stress results are correct: Note: the high stress is actually on the Branch of the tee (ex. Seg Q, H13), compare this information to the original modeling technique where the high stress was located on branch portion of the tee node point (ex. H07+). Confirmation that the results are identical. Question: Why is the new modeling technique color plot so different compared to the original color plot image above? Answer: The Header segment is hiding the complete color plot near the connection point (ex. H13). To better understand, hide the header segment (ex. H) to see the true color plot for the branch segment (ex. Q): Conclusion: There are more than one way to model a Tee in AutoPIPE. Both modeling approaches calculate the same stress results and display color plots correctly. Due to the graphics engine in AutoPIPE the first modeling approach displayed the color graphics on both sides of a node point that was 1/2 run and branch of a tee. The second modeling approach where one segment is the entire run of a tee and another segment is the tee's branch is a better modeling approach to reduce the number of warnings in Model Consistency Check report and to better display code compliance color plots.

Forum Post: Lift-off check analysis feature : Do occasional load cases take into account the hot sustained stress
I understand that the expansion stress and sustained stress calculated by auto-pipe take into account the pipe lifting off supports during operating case (as each operating case is defined in separate analysis set as per 31.3 option). But what about occasional stresses? As per default analysis set, the earthquake loads are defined in an analysis set with more than one temperatures. Does it mean that when using "Multiple Analysis set (31.3)" option, the seismic stresses will be combined with "worst hot sustained stress of all operating cases" or hot sustained stress corresponding to the defined "initial case for occasional loads" or "sustained case corresponding to cold rested position". Am I right in thinking that I should combine only one temperature case with earthquake loads in an analysis set if I want to combine hot sustained stress with pure occasional stress. (as lift off check is not possible for an analysis set with more than 1 temperatures)

Forum Post: RE: Lift-off check analysis feature : Do occasional load cases take into account the hot sustained stress
Just found the following on help file : " Note that if there are multiple analysis sets available then category maximums like ( SUS ), (EXP), (OCC) etc. takes the maximum stress across all analysis sets. Example: Consider a model with two analysis sets with different options. Analysis set 1 has default sustained combination "GR + MaxP{1}" and analysis set 2 has default sustained combination "GR + MaxP{2}". Assume that the stress value for "Gr + MaxP{1}" for a point is 100 psi and the stress value for "Gr + MaxP{2}" for the same point is 200 psi. When calculating the stress for the default Occasional combinations which includes category maximum ( SUS ), then AutoPIPE will take in to consideration the maximum sustained stress across both the analysis sets i.e. ( SUS ) will be equal to 200 psi for all the combinations for both the analysis sets. Similar approach is applied for user defined code combinations." I think that explains it. Since the occasional combinations included (SUS), therefore, it combines maximum sustained stress across both the analysis sets with pure occasional loads.

Forum Post: RE: Lift-off check analysis feature : Do occasional load cases take into account the hot sustained stress
Manu, Glad that you were able to figure it out. AutoPIPE does take in to consideration the maximum sustained stress across at a given point all analysis sets (hot or cold) for calculating occasional stresses. Your answer would help other users with same / similar question. Regards, Bilal Shah

Wiki Page: "ASME B31.3" Piping Code Enhancements and Defects for AutoPIPE
The following ASME B31.3 Enhancements and Defects have been logged for inclusion into a future version of AutoPIPE: Note: if an enhancement has not been added to the program, log an Service request for that enhancement. The more requests logged per an enhancement, the quicker the CAE development team will add that feature to the program. TFS-E633755: Add ASME B31.3-2016 Description: Add ASME B31.3 2016 edition Development Project: TBD TFS-D566491: Add feature to specify user defined Sus In / Out plane moment index at a node point Development Project: TBD TFS-D334683: Non-linear analysis is incorrectly flagging supports as lifting off Description: It was determined that a change in the support lift off logic for the non-linear analysis engine was altered in 10.0, which introduced an inaccurate check for displacement for B31.3-2014. ( see details here ) Steps To Reproduce: 1. Open model 2. Create multiple analysis sets (B31.3 -2014) 3. Run analysis. Note that there is at least one lift off warning 4. Open Support output report. Note that under all vertical stops and vertical guides, forces are in the -Y direction Avoidance: The warning serves no other purpose than to alert the user to a support lift off. The Show Support Lift-Off report under Results menu still works properly as the logic is independent of the analysis engine. There will be an issue for ASME B31.3 2014 models containing an analysis set with remove lift-off supports option checked. This may produce overly conservative results, if not correct results. Again, this is only affects AutoPIPE CONNECT 10.00.00.10, Development Project: This defect will be corrected in AutoPIPE CONNECT Update 1 to be issued in early March 2016. TFS-E156301: B31.3 Code Fig 323.2.2B MDMT reduction based on stress ratio Development Project: TBD TFS-E138562: Add ASME B31.3-2014 Description: Add ASME B31.3 2014 edition Development Project: 09.06.03.xx TFS-E121414: B31.3 Para 323 Avoiding Impact Test Requirements Warning Description: AutoPipe to incorporate minimum temp warnings per figure 323.2.2B(ASME B31.3) Therefore give the user a warning based on input temps if the piping in the model falls below the allowable curve that would require impact testing for lines. Development Project: TBD CAE-CR-10741: B31.3-2010: Add functionality for user to enter axial and torsional SIF Description: ASME B31.3 2010 edition uses axial and torsional SIFs when calculating Sustained stresses. The default values for both the SIFs are 1.0 in absence of more applicable data. This enhancement will allow the user to be able to enter Axial and Torsional SIF values using the User Joint & SIF dialog. These values will be used in sustained stress calculations. Development Project: 9.6.0 CAE-CR-10585: Add B31.3 2012 piping code Development Project: 9.6.0 CAE-CR-10311: Online help for Use Alt. Occ. Allow must include a table for ASME B31.3 2010 Description: The Allowable Occasional Stress depends upon the Tcr values of the material used defined in the library instead of the operating temperature. The Online help for "Use Alt.Occ.Allow" does not have the table for ASME B31.3 2010 and only includes table for B31.3 2006 and before. Development Project: TBD CAE-CR- 3268 (TFS-E110599) : Add fatigue analysis for ASME piping codes Description: Add fatigue analysis for thermal, pressure and wave and dynamic loading. Development Project: TBD See Also Piping Codes Enhancements & Defects Bentley AutoPIPE

Wiki Page: C.08. Can AutoPIPE model the stress on pulling a pipe into a directional drilled hole?
Applies To Product(s): AutoPIPE Version(s): All Environment: N/A Area: modeling Original Author: Bentley Technical Support Group Date Logged & Current Version June 2015 09.06.02.06 Problem: Can AutoPIPE correctly model and analyze the stresses created while piping is being pulled through a directional drilled bore hole underground? Solution: The CAE development team does not have any recommended workflow for modeling a pipe being pulled through bore hole. This will be more of a dynamic problem i.e. the pipe is actually moving and is not restrained to remain in place. An approximation may however be made by defining soil properties that would describe the different stiffness values for the pipe/soil interaction. The tensile pull load on the pipe may be modeled as a static load acting on the end of the pipe that is being pulled. Any other loads that may act on the pipe during this process like soil weight acting on top of pipe, buoyancy forces, and frictional forces will need to be modeled in addition to defining the approximate soil stiffness values. It seems that for such type of designs the software may need to perform large displacement analysis - which AutoPIPE is not capable of performing, or for that matter other pipe stress analysis applications.

Wiki Page: 05. How to define building settlement for a Nuclear codes?
Applies To Product(s): AutoPIPE Version(s): ALL Environment: N/A Area: Modeling Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: How to define building settlement for a Nuclear codes? Solution: Example for inserting Building Settlement for pre-verification stress report is mentioned here . For stress summary report, this option is not yet available. An enhancement has been logged to be able to account for that in the future releases. Currently it seems that the results for equation 10a(10b for 2007 and later) would be reported as zero.
