Need to calculate wind loading/foundation for a weird project!?

Turning metal tank into a fun tower (think lighthouse) 32' high, 8' dia, 1/4" steel 9,000 lbs Put it up on end on concrete slab with J-bolt anchors 12,000 lb wind load (Very windy hilltop) soil bearing cap 4,000 lb ft2 I'm thinking a 12' dia slab would be more than adequate...what do you... show more Turning metal tank into a fun tower (think lighthouse)
