Thickness calc in Bedinar
(OP)
Hi There,
Sorry if my question is so basic. actually i was reading Bedinar handbook when I found that in 4.8. Illustrative example, Sa is devided by 4 before using it in calculation. Can you let me know where is that factor of 4 coming from?
Thank you

55000 psi is the minimum tensile strength for SA-516-55
4 was the design factor back in the old days. I think it was prior to the 1999 Addenda of the Code???, not so sure about the edition or addenda where the design factor changed from 4 to 3.5

Below is a link to an old article about the design factor or design margin. Some good info and historical background in there.
