A special option of bracing the 3 × 3 grid with the associated bipartite graph below. The edges represent the bracing elements of the associated column and row of the grid. The colorscheme indicates the redundancies of the diagonal elements only. Kinematic mechanism and state of self-stress shown on the right.

Structural engineers often want to have a redundant structure where the loss of a member would not lead to structural collapse. For a truss, adding a bar beyond that required for static determinacy renders the structure redundant, but what is the spatial distribution of the static indeterminacy within the individual elements of a framework? Can an...

... lastly added diagonal on the top right (r 1 , c 3 ) is the most redundant one, meaning that its removal would have the least impact regarding structural performance. Figure 4 shows a bracing that also uses five diagonals, like the statically determinate version above. However, their specific placement results in a structure that is kinematic and has one state of self-stress. ...
