Hello everyone,
I build a parametric truss in Grasshopper with the help of Karamba3d. The truss exists of “cubes” with a certain eccentricity towards the center of the cube. Somehow due to the joint design with Karamba3d, a torsion in the truss appears. I am not sure why this is happening and how to fix it. Since the truss is completely symmetric I do not think that this should happen. Can somebody help me out? As you can see from the figure, the reaction forces are not symmetric and neither are the moments when the joints are turned on. It can cause high stresses in certain members while in other parts of the truss the stresses are low.
