A simple definition using the 'BESO' and 'resulting element forces' - components of the latest release to evolve a topology and get evenly distributed axial stress.

is this addon something like sap2000 component? for frame structure ?

thanks for your reply.hope it will be as powerful as the general fea software, such as sap& midas. good job. i am learning it now.

Hello David, we will update Karamba as soon as possible.

I was wondering if Karamba can identify a compression members in a truss/space frame?
Is there a Karamba definition that will allow me to identify the compression members for any kind of truss or space frame?

For example, I want to select my truss/space frame from Rhino, then define the supports, nodal forces and some other parameters too, and then Karamba definition will allow me to get all members under the compression to be selected.

Can this be done in Karamba?

If it can, can anybody help me with it please?

Thank you.

Hey Najna,

this will do it:

... assuming you already built up your model. Your question was hypothetic? Karamba gives a multitude of results, including the ones you asked for. It also includes a BESO-designer considering the characteristic 'force' of your choice (bending, normal force, deformation energy...), and in the new release (to be available in the next days) also a 'Tensile / Compressive -designer' where you can set tension-only or compression-only elements (this technically also, like BESO, means a solution has to be found iteratively by the system).

Best, Robert
