Specifies the type of Bourdon pressure effect used. The Bourdon effect causes straight pipe to elongate and bends to open translationally along a line connecting the curvature end points. If the Bourdon effect is disabled, there will be no global displacements due to pressure.
-
None - Disables the Bourdon effect. There will be no global displacements due to pressure.
-
Trans Only - Includes only translation effects (Bourdon Pressure Option #1).
-
Trans + Rot - Includes translational and rotational effects on bends. This option may apply for bends that are formed or rolled from straight pipe, where the bend-cross section will be slightly oval due to the bending process. (Bourdon Pressure Option #2)
-
For straight pipe, Bourdon Pressure Option #1 is the same as Bourdon Pressure Option #2. For elbows, Bourdon Pressure Option #1 should apply for forged and welded fittings where the bend cross-section can be considered essentially circular.
-
The Bourdon effect (Trans only) is always considered for FRP pipe, regardless of the setting of New Job Bourdon Pressure.
