Form-finding and fabrication of BeTA pavilion: a bending-active biotensegrity textile assembly
AbstractBorn in art, the tensegrity logics have been advanced in disciplines from architecture and human anatomy. Biotensegrity principles introduce an adaptive, ‘living’ structural model characterized by networks of interconnected components and tendons with a shape adaptive capacity. Bending-active is an approach to form-force equilibria that adopts actively curving beams and surfaces within their elastic ranges. BeTA Pavilion explores the formal opportunities of biotensegrity logics using elastically bent glass fiber reinforced plastic rods and CNC knitted textiles. Its bending-active system (inspired by animal vertebrae typologies) is composed of prestressed and self-stabilized tetrahedron modules that are arrayed and sequenced to produce structural equilibrium with a bandwidth of dynamic motion. The paper details the iterative design process employing physical and computational modeling and testing for the new adaptive and dynamic structural assembly coupling bending-active textile hybrid with biotensegrity logics.
