Bolted Tanks

Bolted Tanks

(OP)
Hi all,
The PE I work for is out of town and our Mech guys "don't do tanks." So here it is - Working on a 24' diameter pressurized tank.  The tank consists of 3 rings with an average width of 13'. The shell thickness is 3/16" A-36 steel.  The tank is bolted construction with a top and bottom flange that is welded onto the panels (3/8" plate 6" wide). The sides are overlaped and reinforced with 3/8" plate 6" wide. The bolts are A-325 5/8"diameter.  The operating pressure of the tank is about 1psi (20"wc)with an explosion relief vents that engage at 3.25psi. Ok, here is my question: I calculated my tangential and axial stresses (2.496ksi and 1.248ksi respectively)but I am a little confused as to how this data translates to the bolt spacing along the edges. My preliminary calcs give me 5 1/4" o.c. at the overlap and 4 3/4" o.c. at the flanges. Am I on the right track?

Have you gotten the seismic overturning moment?
