Floating Roof Tank with COADE Tank

[bowosumarwo]

Hi there,

Anybody know how to calculate floating roof tank with COADE Tank software? Please share if you know how to do it.

Thanks in advance.

I am sure one can not calculate floating roof tank with COADE Tank Software. You need some kind of proprietory design and drawing. Hope and wait for someone to here.

Thanks for the info brother...

Yes , the floating roof is a structural part;

It is covered by a special appendix (H) in API -650 ? main points =

ensure floatation with two punctured adjacent compartiments;
Ensure floataion with a liquid specific gravity of 0.7
roof to be able to withstand 250 mm of water from raining for instance;

Thanks bro... Instead of using Appendix H i'm using Appendix C for single deck floating roof and i already got the sample calculation from Guide to Storage Tank and Equipment (many thanks to someone who has upload that great handbook).

coade TANK software

you can not calculate the floating roof alone and as such. the reason were given above by the participants

But the tank = yes, simply calculate as an OPEN tank

but for the seismic , you have to add an estimate of the roof weight

the "Guide to Storage Tank and Equipment" contain a not finished floating roof calculation... and this book contain many many "mistake", but that book is a very very good start point for solution your problem (I made my floating roof design example with that book, but this book contain many many uncorrect equtation)

Hello Sir, may i know what are the uncorrect equations that you were mention in that book....? Thanks in advance...

[tturit]

yes...so... I forget most of all, but I find some...
one of these little and horrible mistakes (yes, horrible, because without these mistake, this book is the best for Tank designink, and very good guidence for engineering thinking, just a little bit caotic structures...):
Eq.3.39 Beta (the bending constans) not correct...(pls, look that in Roark Formulas for Stress and Strain, Cylindrical Shell Formulas, or Maan H. Jawad - Design of Plate & Shell structures or other book for Elasticity)
and other:
6.4 Internal floating roofs calculation...this is not finished calculation, and if you read the reference documantation (Roark, Stres an....), you will be surprised, because the calculation constans is not correct...)
etc etc...
I made this for personal use, but I share it, may be you can find some good idea for your tank design:

Thank you for your informations... I have download your book and still need to catch up the language problem, but the equations were talking louder than words
