Radial cracks from 10 ft dia storage tamls in containment
Radial cracks from 10 ft dia storage tamls in containment
(OP)
I am evaluating a storage tank concrete foundation and cannot determine a plausible cause for the cracking pattern. I was wondering if anyone had seen a simular pattern?
I evaluated the foundation using a fea analysis and found it adequate as long as the subgrade modulus is about 90 lb/ft^3.
Facts
Bearing cap per 1994 report 2000 psf
10 ft dia tanks 15 ft appart 10,000 gal cap ea
12 in slab no 4 at 12 in top n bot
Radial crack pattern 10 ea tank even aroun perimeter
2 ft high containment wall 1 ft thick. No cracks in wall except for two.
40 ft by 36ft. Tanks ae 15 ft fr9m one side.

Are the tank walls steel or concrete? How much gravity load is transferred from wall to slab?
