API Steel Dome Roof Tanks

API Steel Dome Roof Tanks

API Steel Dome Roof Tanks

(OP)
Where can I find information on designing and constructing of dome roofs for API tanks?

RE: API Steel Dome Roof Tanks

API 650 has limited information but still some.  For small tanks this is probably enough.  How big and where?

RE: API Steel Dome Roof Tanks

Ther is a book about the design of Silos , bins and Hoppers.

Design of Steel Bins for the Storage of Bulk Solids (Prentice-Hall international series in civil engineering and engineering mechanics) (Hardcover)

Authors = Gaylord and Gaylord

This book contains a dedicated chapter for conical and dome roofs including their superting structures.

I am myself busy doing something on this type of roof design with Mathcad..and want to discuss and exchange e-mails about it..

RE: API Steel Dome Roof Tanks

I am curious and will be happy to review your MathCAD files, I have the API dome roof programmed (it is a trivial program)

RE: API Steel Dome Roof Tanks

(OP)
Thanks guys for the info.  There is one tank project in particular that is in northern Canada and is 60 feet in diameter.  However, I am looking for general information on typical plate layouts, roof to shell connection, etc.  Once I have some general information I will run it through our finite element program to analyize the stresses.
I am also looking for general information on how to construct these types of roofs, eg, are the plates rolled in two direction or cut flat to a particular pattern, then bowed during construction.  
Carthago; I would be more than happy to share information with you.

RE: API Steel Dome Roof Tanks

I think design of roofs at least conical ones supported by a structure did start with Brownell and Young book " Design of process equipment",there is a dedicated chapter to tanks and it deals also with the structure supporting their roofs, with worked examples.

Major softwares like Tank and Etank are almost entirely based (for roof design) on this particular book.

The problem with Brownell book and with these software is
that they deal with simplified cases e.g.=
1- the roofs are horizontal
2- this means that supporting the beams and rafters
 are also horizontal
3- this also means no horizontal reaction acting on the shell or on the inner ring.


Nevetheless this book can form a good basis nowadays to design almost roof type..
 

RE: API Steel Dome Roof Tanks

The details will generally be worked differently by different fabricators.

If the roof is dished to a radius, it's a "dome".  If plates are rolled or formed in one direction only, it is an "umbrella".  These two terms are often used interchangeably.  Connections to the shell and at the top will vary, as will general layout of the roof itself.

If this is an actual tank, either in place or proposed, you'd need to speak to the fabricator for specific details.

RE: API Steel Dome Roof Tanks

I have found "Above Ground Storage Tanks" by Philip E. Myers to be a decent resource for tank design in general with some good info on roof design.  Check it out on Amazon.
