"Engineering-International" Design Spreadsheets 1

[wishnias]

Has anyone purchased the spreadsheets found at

http://www.engineering-international.com

and could vouch for their accuracy and/or value? They seem well put together, but the creator, a Daniel Tian Li, SE out of California, would not give me references when I contacted him, citing 'marketing games' he doesn't want to get involved with.

If not, could anyone point me in the direction of a useful seismic analysis tool?

From the one or two spreadsheets I opened, the references are quoted there.

I can't see what marketing games there are though if the calculation methods are readily available on the references.

By references, I meant people who have used them that I could talk to, see if there are bugs or pitfalls that aren't apparent from the locked versions.

Our firm bought them and I have used some of them occaissionally. In fact I had forgotten we had them until I read this posting.

No idea what they cost - so were they worth it - I do not know.

One problem we have is that all of the spreadsheets are protected and being engineers we would like the ability to tweak them at times for our own specific cases.

The spreadsheet for combined footings gave much more conservative results, for footing thickness, than the way I always did them. Being conservative is a good thing. I am not saying they were wrong - but I chose not to use it and continue those designs like I always had done.
