algorithmic modeling for Rhino



Karamba is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames and shells.

karamba is an interactive, parametric finite element program. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.

karamba is being developed by Clemens Preisinger in cooperation with Bollinger-Grohmann-Schneider ZTGmbH Vienna.

Angular steel cross sections to cross section table 3 Replies

Hi,Can you suggest a way how to use equal angles as steel cross sections for Karamba? How can I build up the cross sections table?My main issue is to apply a new axis of buckling, the "u" or "v"…Continue

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.

Karamba is an interactive finite element program for frames and trusses.

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

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.
