Design of Circular Flat Endplate with Stiffeners
Design of Circular Flat Endplate with Stiffeners
(OP)
I have been asked to look into designing a circular flat endplte with stiffeners havin a diameter of 3m~5m for storage (water crude oil, chemicals) horizontal tank. ASME Sec. VIII Div. I has discussed it but without stiffeners, so the resulting thickness is too big even atmospheric condition. Can someone recommend a design procedure/information? I have 5 reference PV books by Megyesy, bednar, Young,etc but does not discussed design procedures on this topic
In particular, I am unsure how to consider the interaction of bending stress, shear stress, allowable deflections. I'm in the Philippines, so my references are limited. I also surfed the internet but nothing so far.

I believe UL 142 has some guidelines on stiffeners, but I don't recall the details- and it's an expensive standard, too.

Thanks. Will try.
Arto,
Thanks. Basically it would take time before I could get the book as part of my additional reference. Can you provide advanced scanned copy at the moment? aobautista@bhpi.com.ph

Are you sure that you want to do this ?
Many times it is cheaper to purchase and install a dished head than it is to design, fabricate weld and inspect a flat head for a storage tank.
What is the diameter of the tank and why must you install a flat head ?

UL 142 refers to the subject as: "Stayed Flat Heads"
Sorry to have used term "Baffles"
Thanks,
