Tank Anchorage

[elhamydy]

Hi All
I have a question how to find the information below for Tank Anchorage :
-N [dless] = Number of bolts selected
-Db [mm] = Bolt nominal diameter

And if any one have the document AISI E-1 specification, Volume ll, part VII,

Tanks in advance
Best Regards

Is this an API-650 tank ?

API-650 contains rules about the number of anchor bolts, spacing and bolt sizes

Assuming anchorage is required, calculate the minimum number of bolts required based on maximum bolt spacing, and round up to a multiple of 4.
Calculate root area required per bolt, look in tables of bolt properties to find what size bolt that is.
Include corrosion allowance and minimum bolt sizing requirements if applicable.
If the bolt size or the anchor chair comes up unreasonably large, then increase the number of bolts and try again.
