I've had a few other folks with the same reuest for metric versions. I personally have never worked on an all-metric required project in my 36 of practice, however that's not to say that it won't still come. However, since I do these spreadsheets on my own time and distribute them freely, I'm obviously inclined to do what facilitates my own work and the work of the people that surround me.

Since I'm still a practicing engineer, finding the time to do all that I have on my wish list is a very difficult task at best. Also, not being experienced with metric units, I'm not even sure what the commonly used set of units would be for replacing feet, inches, kips, ft-kips, ksf, ksi, and psi.

As you know, all my spreadsheets are protected, but not with a password. Thus, I encourage you or others to have a go at it. You could reach me by email via my forum contact information if you wanted me to review what you have done. That's the best answer that I can give you for the moment.

I have also attached a PDF file containing example problems run in the PCACOL program (2002) which should help demonstrate the level of accuracy of the "Uniaxial" worksheet in the "RECTBEAM.xls" workbook. What I did is run some examples with the "Uniaxial" worksheet using varying percentages of longitudinal reinforcing. Taking the interaction point results from the spreadsheet, I input those points as factored loads into the PCACOL program. Those points are then displayed right along with the PCACOL generated interaction curve for direct comparison.
