## 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

## Non-linear Frame Analysis – Scipy solvers

The frame analysis spreadsheet presented in the previous post has been updated to use the solvers included in the Scipy package. There is now an option to use either the Cholesky solver, or an iterative sparse solver. The main advantages of … Continue reading

## LatPile update

I have just posted an update to the LatpilePY spreadsheet, fixing a bug in the way in which it read the first row of data from input PY curves, which was resulting in the program failing to run if there were … Continue reading
