La forma e l’algoritmo. Progetto computazionale (generativo) di sistemi tensegrali

This essay addresses computational strategies for including structural and performance-based considerations within the early stage of an architectural design process, linking together shape and strength from the very beginning of this process. Being structural behavior affected by geometric form, the greatest potential for structural reliability, spatial quality, as well as sustainability goals, occurs when formal and structural issues are both controlled in the conceptual design phase. According to the progresses in digital engineering, free-form design, relying on ‘postengineering’ simulations, on one hand enriches geometric exploration, widening formal and spatial experimentation, on the other hand it may underestimate some relevant design issues, postponing them to subsequent engineering optimization demands. In this regards, we propose a performancebased structural morphology framework, for validating design process through real-time threedimensional modelling and qualitative analysis simulation; a framework which intends to explore broad ranges of alternative solutions proved on the early stage of design. These graphic-based algorithmic models represent an innovative methodology – so called dialectic form-finding – for visualizing technical process and structural considerations, also integrating environmental insight into a reliable architectural design. As an example, a tensegrity bio-inspired and structurally integrated morphogenesis is presented.
