Simply follow the instructions given in 5.9.7 of API 650
Step 1) Calculate the unstiffened height of the tank
Step 2) Calculate the Tansposed width of each shell course.
Step 3) Transformed shell height = Sum all transposed width of all shell courses.
Step 4) If the sum transformed shell...

I cannot explain all at once, but I can explain the effect on saddle (As per Zick's Analysis)
In the zick analysis check is there are two check for longitudinal stress between saddles.
1) Compressive Stresses
2) Tensile Streses
There will be no direct effect on the...
Which software are you using for that matter?
COMPRESS has this option of evaluating nozzle loads based on MAWP. It uses calculated nozzle MAWP and uses the same to perform nozzle piping laods as per WRC 537 (or WRC 107).
