hydrodynamic effect on circular steel water retaining tanks
through this message i have two queries to ask.
1) has anyone designed a circular steel tank retaining water? if so could you please share the detail drawings of such a steel tank.
2) if such a tank is located in a seismic zone, how have you considered the seismic effect on stored liquid.
could someone please share his/her experience with me in this area of structural engineering.
thanks

suggest you get a copy of awwa d100 and awwa manual m42.  awwa d100 includes fairly complete seismic design for water tanks in section 13.  manual m42 discusses some of the detailing and design issues.
for detailing, contact local tank suppliers or fabricators.  let us know where you are as well, we may be able to direct you to some suppliers.
hi jstephen,
thank you very much for your reply. i'm based in pune city close to the western coast of india. i'm looking at the option of providing a steel tank resting on ground instead of concrete which might be economical. diametar of the tanks is varying from 20m to 28m.
could you please suggest me the price of the referances and how could i purchase them?
thanks again for your help.
cheers

hello ameet,
you could also use api 650. i know api 650 is available for purchase (about usd300) from global engineering documents via download.  if you purchase it this way, you can only print it once.  it does however, save shipping and time.
appendix e covers seismic design and is based on a paper by wozniak & mitchell.
awwa d100 is currently a little more up-to-date as compared to other building codes.  i recommended it because i'm familiar with it (i'm in the usa).  you may be able to locate other standards that are equally useful.  you will need local information as to the seismic loads, as awwa d100 only includes seismic maps for the us.
both the awwa standards should be available through the awwa website at
you need to buy the pca guides that apply.
