Piping code calculations

1. Be sure to review the following AutoPIPE online help information:
   
   Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations>
   
   This area describes variables, equations, and methodology used by AutoPIPE to produce output reports per the code associated with the piping system database. AutoPIPE is capable of generating actual and allowable stresses for each of the applicable stress categories (depending on the current, analyzed load cases) for all codes listed below. Please Note: The Standard edition only has access to 4 ASME codes and European code EN13480 as shown in the Getting Started topic "AutoPIPE Standard vs Advanced vs Nuclear".
   
   Select the Pipig code hyperlink below for general questions on the respective code calculations.

2.  Why does AutoPIPE ignore axial force in most of the code equations?
   
   Answer: Confirm the model is considering axial force, as this option by default is turned OFF. See Tool> Model Options> Results> "Include axial force" option
   
   Excerpt from online help:
   
   The piping codes ignore the effect of axial force for calculating stresses in the sustained and occasional categories (only bending moments are considered, see Code Compliance Calculations). This option has been provided to allow the inclusion of axial force effects. By default this option is unchecked....
   
   See online help for more information on this option.
