Rectangular storage tank leg design

Rectangular storage tank leg design

Rectangular storage tank leg design

(OP)
Hello every body,

I have to present hand calculation for a rectangular storage tank. i have designed tank walls besed on Kanti.K.Mahajan reference book.

I am involve designing tank legs. the tank is supported by 4 legs.

loads are : wind, seismic, dead load

i will be appreciated if anyone offer me a book or standard for hand calculations.

the tank is not pressurized so ASME Boiler & Pressure vessel code is not usable. in addition, the tank is rectangular, so API650 is not usable too!...

RE: Rectangular storage tank leg design

Neither ASME or API 650 cover leg designs, period, whether pressurized or round or what. AWWA D100 includes design requirements for leg-supported tanks (intended for municipal water towers), but doesn't really help you design, it either.
Bednar's Pressure Vessel Handbook includes some information on leg design for vessels that may be of help. The main point being that he considers legs to be partially restrained at the base.
If the tank is very small, you can make some very conservative assumptions without excessive extra cost (cheaper to throw some extra material in there than it is to do the analysis to show it's not needed.) If the tank is large enough, it may be worthwhile to do finite element analysis to design leg connections.

RE: Rectangular storage tank leg design

I would probably look at providing a complete steel support frame that could resist the lateral loads independetly....this would simplify the connection of the tank to the steel frame...would also have to check the affect of the lateral deflection on the concrete tank, as noted above, the majority of info published is for steel tanks.....
