Hello Fellow Members,

I was a bit surprised when Richard finally decided to close the thread on trunnions with the advice of another member and after reading the whole documents it seems to me that the issue that made Richard closed it was that the thread has shifted to the issue of copyright legality in Aaron's wilingness to share the documents on MW Kellog trunnion calcs procedure. I have seen the documents, has evaluated and tried it several times at home and found it somewhat inconsistent. Also, the guides in there are somewhat confusing. And so if Raul would try to check the thread on trunnion, he might end up studying the same thing. And might finally came to a conclusion that he may need FEA or FE PIpe, WRC 448 guidelines (as John L. has issued as a tip). I thought of validating that MW Kellog calculation guides using FE Pipe or FEA to make it more accurate emprical equations that could check trunion sizes in terms of limiting loads or limiting stresses. So far I remembered Anindyastress having said to have trunnion calcs but I am not sure if he meant based on that MW. Kellog calcs. I hope anindya could correct me and also I really hope at that time the thread could have been converted into developing a clearer procedure of quick check on trunnions - a somewhat member-effort.

After talking to an engineering manager of a particular engineered pipe support company in Texas, I relaized too that some pipe support designs on trunnons do not consider localized stresses on trunnions - just like my working environment I should say. Hope Anindya could share us his working skill on this. Just my opinion regarding trunnion, dummy leg, duckfoot.

Regards.
