Form-Finding of the ParaKnot3D’s Gridshell with Equal Line Length Rods
-
Cristoph Dijoux
Abstract
- A concept to efficiently realize doubly curved shell structures has been developed and presented in the context of the ParaKnot3D-Pavilion project: low variance of elements by solely using similar-length rods, concentrating the structural complexity into 3-D-printable nodes and planning them with a certain rigidity to guarantee an easy erection process. Besides the full parametrization of the resulting individual nodes, defining a grid with equal line lengths, that shows membrane load-bearing was necessary. The usual one-step approaches of deforming a flat grid or generation of a grid on a shell surface could not satisfy these constraints. The difficulties in satisfying the constraints and a way to overcome them are presented. A multistep approach has been successfully used in the construction of a pavilion and allows defining grids of equal-length rods, while preserving the optimization goals of structural form-finding.
