Beam geometric non-linear effects

A quick and convenient way to allow for the effect of deformations on the behaviour of beams and columns under axial load is to adjust the beam stiffness matrix, so that the calculated deflections are in equilibrium with the applied … Continue reading

Using the Frame Analysis Spreadsheets

Following some recent questions in the comments, here are some answers: How can nodal moments be created? The current versions only allow for forces to be applied to beams, but any point load or moment applied at the start or … Continue reading

Installing Frame4 and 3DFrame

Following a recent comment I have added a VBA only version to the download files of the frame analysis spreadsheets: 3DFrame.zip Frame4.zip The VBA versions should work on any version of Excel from 2007, with macros enabled, without any further installation. The … 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

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
