has anyone purchased or used the spreadsheets from this website? it looks to have quite a few spreadsheets with code references with the calculations. the author is daniel t. li.
thanks for the input.


no, but they look interesting and reasonable.
i did. composite beam design. works good.
just curious....
how do you know it (the composite beam design) works well? did you have some well known, or well worn, or trusted solutions to compare to? or did you do a hand calc?

i did hand calcs. also i ran aisc manual 9 solved examples and answers and steps match.
i have purchased several spreadsheets (steel brace connections / concrete shear walls etc) from daniel t. li and they all seem to work well. the results have all matched well with the hand calcs. the only draw back i have seen is the design is not always complete and the additional checks required are not mentioned in the spread sheet.
thanks for all the replys. has anyone used his concrete column and beam spreadsheets?

you're better off to write your own spreadsheet. the only way to verify the correctness of a spreadsheet is to verify each equation. a difficult task with excel as the formulations are so cryptic, as compared to mathcad, for instance. it is folly to think you can verify a spreadsheet, or any software, for that matter, by running a few example problems. by the time you're done deciphering the formulas in excel, you can write your own spreadsheet.
i agree, it's easier to follow in mathcad
