It extends graphic statics to a fully three-dimensional method to design and analyse spatial frames. These examples demonstrate the benefits of bi-directional manipulations of form and force diagrams in the structural design process. determine the equilibrium of general spatial frames.

Let a 3D object B be supported by n frictional contacts against gravity in. An implementation of the proposed framework to real design scenarios is presented through two case studies. The static equilibrium condition for a given n-contact arrangement is given. The cross product is your friend.If you found this video helpful, please consid.

Resulting planar graphs can be then used as a base for the assembly of 3D force diagrams, without altering the static equilibrium of the structure. This engineering statics tutorial goes over how to solve 3D statics problems. In the non-planar case, the proposed procedures rely on the preliminary topological planarization of the graph by cutting the crossing edges and reconnecting them to one or more newly inserted auxiliary vertices.

Several procedures for the construction of a vector-based 3D force diagram for any given 3D form diagram with an underlying planar or non-planar graph are identified and described. It is intended to support the collaborative work of structural engineers and architects from the conceptual phase of the design process. This article develops a vector-based 3D graphic statics framework that uses synthetic and intuitive graphical means for the analysis and design of spatial structures such as networks of bar elements in static equilibrium.
