Zick analysis - Metric or Imperial 4

[iken]

Hi All,

Just wondering (as I am about to embark on creating a spreadsheet for horizonatl vessel supports using the above), if anyone can advise if all the factors used in zick's methods, can be used direct with metric figures, or will I need to conert to imperial to use these factors, then back to metric?

Thanks,
Iken

Seen it done in metric.

iken,

I suggest you create two spreadsheets...one for imperial units and the other metric. Then compare the results.

Better to find out yourself than from random strangers in the internet.

It should be possible to tell from the equations themselves and the definition of the variables and constants involved.

Thanks for the comments.

I have just located a PV book (pv-book.com) which looks as though this will give me what I need, and more.

Cheers,

Calculate with imperial units and convert results to metric, in the same spreadsheet

PD5500 Annex G is based on the Zick method and is metric.

4.15.1 Example Problem E4.15.1 Horizontal Vessel, Zick's Analysis 4-183
Determine if the stresses in the horizontal vessel induced by the proposed saddle supports are with
acceptable limits. The vessel is supported by two symmetric equally spaced saddles welded to the
vessel, without reinforcing plates or stiffening rings. All Category A and B joints are Type 1 butt welds
and have been 100% radiographically examined. See Figure E4.15.1
