It would be very useful to have the entire Eurocode 3 (1993-x-x) written in Mathcad. One could from that spreadsheet cut-n-paste formulaes into the calculations one are doing.
Does something like this exist? It would be a huge job to write it, but very useful for the world of engineers when available.
I don't think you will easily find it. The Eurocode is copyright material.
And yes, it will be a huge effort to build it in Mathcad.
