algorithmic modeling for Rhino
I was wondering which kind of interpolation is used for beam elements in Karamba, and if they take shear deformations into account (Timoshenko beam).
Karamba takes account of shear deformations of beams.
It uses a matrix transformation method to determine the nodal forces from beam loads and cross section forces at arbitrary positions along the axis. For details see e.g. 'Rubin H., Schneider, K.-J.: Baustatik Theorie I. und II. Ordnung, Werner-Verlag, Düsseldorf, ISBN 3-8041-3084-4'. The book is however in German language. When you google 'beams matrix transfer method' you will find contributions in English as well.
that's exactly the information I needed, thank you.
