Abstract

enTensegrity structures, characterized by their architectural distinctiveness and a static equilibrium based on self-stress, are generally modeled numerically as ideal pin-jointed trusses. However, this assumption neglects the non-linear effects that induce parasitic moments within them, leading to divergences between experimental observations and numerical simulations. Therefore, the objective of this thesis is to evaluate the influence of these parasitic moments and to identify their source in tensegrity structures. To this end, several numerical methods are developed and compared in order to assess their effectiveness in simulating these effects. Finally, the analysis of two case studies (a simplex module and a tensegrity footbridge) demonstrates that these parasitic moments can affect the internal force distribution by several tens of percent, potentially threatening the overall equilibrium of the structure.
