Hi Dave,
I tried your suggestion of modeling the single-miter bend as bend with miter=1 (and i even experimented with 2 bend angles of 5 and 15 deg. each), but SIF always stayed equal to 1. By the way, the program cannon ignore the bend radius as may have suggested. I computed for new radius using the R equation from Appendix D of B-31.1 (R=r[1+cot(theta)]/2), but it still gave me SIF of 1.
The weird thing is that i even tried increasing the number of miters (2,3.. etc), and still SIF was 1. Can you please explain what is wrong with what i'm doing?
Regarding Art's question, so do you recommend to model trimmed 90/45 deg elbow as bend which the program -in return- will install an SIF that matches the 90/45 deg elbow SIF? won't that be under-estimating the SIF at that specific fitting?
Thank you Dave of your previous reply... and you coming ones!
