A.2.3: Tips for Designing Statically Feasible Structures
Karamba3D can be used to analyze the response of structures of any scale. When using the “Analyze”- component for assessing the structural behavior be aware of two preconditions: First, deflections are small as compared to the size of the structure. Second, materials do behave in a linear elastic manner – i.e. a certain increase of deformation is always coupled to the same increase of load. Real materials behave differently: they weaken at some point and break eventually.
