Custom Beam Cross Section

Hi there,

does anybody know of a way to define a custom beam cross section by specifying A, Iy, Iz, ..., rather than choosing one of the provided standard cross sections?

The background is that I need a "dummy beam" that has zero (or close to zero) axial stiffness, but high bending stiffness.

Best regards
Stefan

Hi Stefan,

the easiest way is to create a custom cross section table file. It is written in csv-format (i.e. can be manipulated via a text editor, Excel,...) and contains the geometry information and cross section properties. You can use the 'Generate Cross Section Table'-component to produce a template file. An alternative would be to copy and manipulate 'CrossSectionValues.csv' which can be found in the 'Karamba'-folder. Supply the 'Read Cross Section Table'-component with a path to your csv-file in order to use the cross sections.

A more general approach would be to define a custom C#/VB component and produce the cross section objects directly (see Karamba Hacker's Manual).

Best,

Clemens
