Hi all,

How can I calculate stress intensification factors (SIF) for intersections having more than three pipes?

I have a line with a cross intersection between four frames of pipe and I don't know how to calculate the correct SIF to apply in CAESAR (CAESAR doesn't calculate SIF for intersections having more than three pipes).

Stress cose used for my analysis is B31.3

TY.

B31.3 offers no guidance on this configuration - you're outside the scope of the Code. You can search this Forum for the word "cross" to see what others have suggested, but you're looking at FEA methods.
