kvram, I've got quite a few spreadsheets that we've developed over the years, and continue to do so as codes change.
However, I cannot give you copies as there are most certainly liability issues involved, and I feel that you would be better served if you simply wrote your own. Most steel design procedures are straigtforward and developing your own program is a very, very good way to develop and/or improve your engineering knowledge.
By writing your own, you have the ability to:
1. Re-learn procedures that you once were taught, but now are a bit fuzzy.
2. Learn new aspects of updated codes as they appear.
3. Have an intimate knowledge of the spreadsheet, what it does, what it cannot do, and all its assumptions.
4. Avoid problems with getting someone else's spreadsheet that may have errors in it that you know nothing about and end up designing a flawed structural element.
If you receive any spreadsheets, I would advise you to spend enough time over them (each and every cell) to fully understand what it does. Many times it takes less time to write your own than to adequately check someone else's.
Just my opinion. Good luck.
