“Structural performance of Kagome lattice for grid shells”, IASS Tokyo, 2016, Symposium: “Spatial Structures in the 21st Century”, August 2016
ABSTRACT: In this paper, we study the structural performance of grid shells covered with triangles and hexagons. These meshes, also known as Kagome lattices have the same node valence as quad-meshes, and thus an equivalent complexity. We present a method that guarantees the covering of free-form shapes with a Kagome lattice with planar facets, making this mesh economically viable. The performance of the Kagome lattice is assessed with two comprehensive parametric studies that vary relevant geometrical parameters like rise-over-span ratio or grid density. The linear buckling load of quadrangular and Kagome lattices is compared and shows that the Kagome lattice is up to 100% more efficient than the quadrangular mesh in the models studied.
