I am trying to do a stress analysis on a 42" nozzle in a 200' diameter storage tank. Talking with another engineer, I have found that because of the large diameter, WRC-297 does not apply, and API-650 APP-P is limited to the bottom two shell rings. This nozzle is near the top of the shell. I have been provided nozzle loadings (forces and moments in all axis). My method of apporach was first to use several formulas from Roarks flat plate analysis to develop stress for input into 2D mohr's circle formula to find principle stresses, but was left with an axial load that was not accounted for. I have tried to work through the 3D analysis but have had trouble understanding the procedure. Any help would be appreciated. I can provide my calcs through email for review.
