I'm still here!! (I was registered 'Lester' but Christened 'William Lester', so the former is legally correct but everyone calls me 'Bill').
I have attached the current version of my general beam analysis program, the input now uses Excel tables for neatness and the 'fill-down' capability, a version with just Mathcad tables is available.
This is a fantastic program, and thank you for sharing it. I would like to be able to modify it to have moment-release supports. I'm not adept at Mathcad's many programming functions, so I'm unable to see where to modify the stiffness matrix equation inputs.
email me a sample problem you wish to solve and I will see what I can do.
