Circular Tank Overturning Toe Pressure 1

[PEStructural]

What is the approach/equation to calculate the overturning toe pressure on a concrete ringwall in a seismic event? I have a 89'x32'H welded steel tank that is in seismic zone 4 and is resting on a concrete ringwall (not bolted down).

Any help would definitely be appreciated.

Thanks,

Mike

PEStructural,

Take your bearing pressure +/- (overturning moment/section modulus of the ring beam). Sorry for the short explanation I will expand more when I have more time.

I understand. P/A +/- M/S when your e is with the kern point. Thanks for the reply!
