Load tabulation for pressure vessel

Load tabulation for pressure vessel

Load tabulation for pressure vessel

(OP)
I am at concept design phase for the foundation of a pressure vessel (low pressure). The base is 60 inches in diameter. The tank is indoors and there are no lateral loads.

What minimum information should I expect the tank designer to provide so that I can design the foundations properly? For metal buildings I would expect base plate details, diameter and spec of the anchor rods, and a tabulation of the loads transmitted through the base plate(s). From the attached screen shot you can see that the designer has only indicated that the total weight is 14,500 lbs, whatever that means. Maybe I am over-complicating things but I don't feel that this is adequate and I would like to know what I should expect. How much is DL? How much is LL? Can the loads be transmitted through bolts only or must the base be grouted?

Thanks in advance.

RE: Load tabulation for pressure vessel

Note that the vessel is shown on its side, and the base is that ring on the far end. The designer should be able to tell you how much is dead load of the vessel and how much is the contents. Normally tanks and vessels are supported on the concrete, not on the bolts, and bolts are only stressed in tension. Anchor bolt loads are normally calculated using an Mc/I distribution of load when moment is present. The base may or may not be grouted. If your area isn't exempt from seismic design, you'd have some seismic loading also. Without wind or seismic, there won't be any design anchor bolt load, and any bolt specification would be fairly arbitrary- typically 36 ksi carbon steel bolts.
