Mechanical Form-Finding of TFS
The numerical form finding of Timber Fabric Structures (TSF) and their structural analysis is pursued in framework of a thesis research project at IBOIS-EPFL.
The deformed state of the TSF can be regarded as the relaxed configuration of a flat initial state under a set of imposed boundary conditions. These constraints can be either the order of panels or their offset at a particular overlap or an imposed displacement/rotation on a degree of freedom for a structural node. Interlacing and then connecting panels together, makes them deform and initiates a pre-stressed module with active bending behavior. We postulate that knowing the flat configuration and the overlaps interpreted as mechanically meaningful BCs suffices to numerically calculate the relaxed form of TSF.
The form finding steps can be resumed as a methodology in the following diagram.
