Beam geometric non-linear effects – Python version

Posted on 12/10/2024 by dougaj4

In 2018 I posted Beam geometric non-linear effects with a VBA based spreadsheet to calculate beam actions and deflections under combined transverse and axial load, allowing for geometric non-linear effects. I have now converted the code to Python, linking to Excel … Continue reading →

Beam geometric non-linear effects

Posted on 21/04/2018 by dougaj4

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 →
