Weld Pattern Section Properties

I would recommend the following;

Thank you very much for your response. I actually own a copy. Blodgett is typical of most other texts in that they provide 10-15 formula for common welds.

I find that my weld groups can often be beyond the scope of commonly provided formulas. Computing the seciton properties is cumbersome.

A more substantial compiliation, such as what I described in the out of print source, is desired.

Again, metengr, thanks very much for your response.

It should be pretty easy to set up a spreadsheet to calc the section properties of different weld groups. It may take some time initially, but be well worth it in the end. What kind of odd-ball weld groups do you have that is not covered by Blodgett?

The L shape and C shape of blodgett consider one side only. Often, weld is applied to both sides completely or only a portion of both side with a specified return. Often times welding is applied to the outside of one angle leg and the inside of the other. Weld can also be applied to the inside of a channel web and the outside of the channel flanges in which case a tru C section is not provided.

Certainly the effort can be put into determining the section properties of any shape and weld group, even using the basic Blodgett formulas. However, I know at one time a very comprehensive compilation of weld group formulas had been published and I'm hoping it still exists in some currently available texts.

I prefer to use hand calcualtion or mathcad with accepted formulas so anyone doing a QA review can see what computaions are being performed versus accepting that the spreadsheet is correctly computing what the preparer claims it has.

Thank you for your response StructuralEIT.
