Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Warning Subarea: Original Author: Bentley Technical Support Group Problem: The following is displayed when performing a model consistency check report: * * * W A R N I N G - MODEL * * * W2143-123 Sh > 20 ksi (138 MPa). In calculation Sh will be set to 20 ksi (138 MPa) for expansion allow at following point(s) Why is that and how to Avoid it? Answer: As stated in the warning message a value of Sh in the one of the Pipe Properties is >20 ksi (138 MPa). So long as the value is larger than that mentioned the warning will be displayed. In general, this has to do with a clause in the code that limits Sh to 20 ksi if Su > 70 ksi (480- MPa) . Note: if using ASME B31.3 Piping code, see the code definitions of Sh for more details on why this warning is applied in AutoPIPE. Avoidance : Option #1 - Accept the warning and let the application automatically change Sc as mentioned to correctly calculate the allowable. OR Option #2 - Physically change the value(s) of the all the affected Pipe Property so that Sh < 20 ksi (138 MPa). then the warning message will disappear. OR Option #3 - Manually set the allowable for the specific code combination on the Load Combination dialog: 1- Un-check Auto Update 2- Manually change from "Automatic" to (enter a valid value).
