Specifies the node number where the stress intensification exists. The software displays the To node of the current element by default. You can also type the From node if that defines your intersection or joint.

If the node is at an intersection, CAESAR II calculates SIFs for all pipes going to the intersection if the intersection Type is specified. You only need to type the intersection type once. The software finds all other pipes framing into the intersection and applies the appropriate SIFs.

If the node is at a two-pipe joint, such as a butt weld, CAESAR II calculates SIFs for the two pipes going to the joint node if the joint Type is specified. You only need to specify the joint type once. The software finds the other pipe completing the joint and applies the appropriate SIFs.

If the node is not at an intersection or a joint, then leave the Type blank and type directional SIFs in the User SIFs Dialog. Entries in the SIF(i) and SIF(o) boxes only apply to the element on which they are defined.

If the node is on any part of the bend curvature, then the following applies:

  • You cannot override code-calculated SIFs for bends by default. A configuration option exists to override this default. For more information, see Allow User's SIF at Bend. If you set Allow User's SIF at Bend to True, then you can specify SIFs for bend To nodes. The SIFs specified in this way apply for the entire bend curvature.

  • CAESAR II applies user-defined SIFs to straight pipe going to points on a bend curvature regardless of any parameter in the setup file. This option is commonly used to intensify injector tie-ins at bends, or dummy legs, or other bend attachment-type of supports.
