Truss Elements Detaching From Supporting Chords & Rigid Body Modes

[Jimmy4 (Jimmy)]

Hi,

When analysing structure using Karamba I notice that as soon as I look at deflections I notice truss elements detaching from upper and lower chords, as well as my entire truss in the middle dissapearing, I am guessing due to the rigid body modes meaning that it is not connnected. Could I please have a hand on how to fix this? I have attached grasshopper file for structure.

Cheers

Hi, you need to make sure your beams are split at their intersections with other elements. For example the beam on which the middle truss sits on:

as well as the top and bottom chords
