Hi
Just use google:

[link Point to another website Only the registered members can access] Or a master thesis FEA vs kellogg

[link Point to another website Only the registered members can access] There are different load factors for the hoop stress in the references above

Does anyone use EN 13480-3 ch 11 for checking trunnions?

I'm looking for Spreadsheet not PDF, please share excel Spreadsheet if anyone has.

suniel,
You are not alone in not understanding concept of trunnion design. There are many trunnion design spreadsheets out there and I would probably say that 75% of them are incorrectly coded with the rest vastly underestimating the stress within the pipe wall. Take care. A lot of the spreadsheets have been plagerised from others with the plagerists not knowing the background theory or the limitations of the Kellog "Choking model" approach.

some of the calc do not really concern on the WRC 297 and 107 requirement. For the Z-axis moment esp. Correct me if I'm wrong.....
for some cases, I do check with PVElite on the stresses act upon the trunnion.
thanks
