## RC Design Functions 7.03

The latest update to my RC Design Functions spreadsheet has just been uploaded, and is available for free download (including full open-source code) from: RC Design Functions7.zip The main new feature in the latest version is a new RCInteract function, which generates an … Continue reading

## Non-linear frame analysis; moment curvature and self-weight

The Python/Fortran/Excel frame analysis program (previous version here) now has several new features added to the 2D-solver routines: The beam bending behaviour may now be specified with moment-curvature tables, rather than the linear-plastic behaviour required in the previous version. Beam … Continue reading
