Geometric Guidance for the Deployment of Elastic Geodesic Grids
CoRR(2023)
摘要
Elastic gridshells are advanced free-form structures enabling curved target
shapes and material-efficient large spans. This paper focuses on a novel type
of gridshells recently proposed employing a scissor-like deployment mechanism.
While recent form-finding advancements have produced fascinating outcomes, a
significant challenge arises when architecturally implementing such mechanisms:
for the realization of real-world structures, professional FEA is necessary.
However, performing Finite Element simulations of these structures proves
surprisingly complex due to the requirement of simulating the deployment – a
task nearly unachievable using uninformed approaches. Therefore, geometric
guidance of the highly elastic gridshells while simulating the expansion is
essential. Present solutions to this predicament primarily involve rudimentary
trial-and-error methods, suitable only for the most basic shapes. We propose a
solution involving the provision of geometric guidance via sequences of linear
displacements synchronized with a universal time parameter. When applied to
chosen positions, this allows for multi-step gridshell deployment and
successfully avoids undesirable buckling issues. We conclude with successful
demonstrations of our method, anticipating our work to pave the way for further
quantitative explorations of these intriguing structures.
