Space frame - Wikipedia
网页In architecture and structural engineering, a space frame or space structure (3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports.
R. Buckminster Fuller. Airplane Hangar, project. 1955 | MoMA
网页This design for an airplane hangar uses Fuller's octet truss to form its lightweight, long-span space frame structure. Patented in 1961, the octet truss is a compound of a tetrahedron (a triangular pyramid) and an octahedron (a solid form with eight triangular faces).
Bending behavior of octet-truss lattice structures: Modelling …
网页2021年7月1日 · The octet-truss lattice forms an effectively three-dimensional orthotropic metamaterial from the material parameters of which one could obtain the effective material parameters (E ∗ and G ∗) for beam models.
Octet Truss - Grunch
网页The cctet truss is simply the IVM realized as an artifact for use in engineering applications. These applications range in size from the nanotechnological to the mega-structural -- or any scale in between (see Angle vs Frequency ).
On the elastodynamic properties of octet truss-based architected ...
网页2023年4月24日 · We design, fabricate, and experimentally characterize three types of octet truss structures, including two homogenous structures with either thin or thick struts and one hybrid structure with alternating strut thickness.
The fracture toughness of octet-truss lattices - ScienceDirect
网页2017年1月1日 · Here we investigate the fracture toughness of a Ti-6Al-4V alloy octet-lattice truss structure manufactured using a ‘snap-fit’ method. The samples had densities between 360 and 855 kg m −3 (relative densities of 8–19%) and free truss lengths between 4 …
网页2018年3月29日 · This paper refers to this engineered material as Octet-Truss Engineered Concrete (OTEC). To make OTEC structures, UHP-FRC and “green” UHP-FRC (G-UHP-FRC) mixtures were developed. 50.8-mm side-length OTEC unit cell specimens with various element diameters as well as 5×1×1-cell
网页The tetrahedral or the octet truss is a doubled layered slice from the space- filling of tetrahedra and octahedra [3]. This space-filling has four plane directions, and the double layer used in trusses is parallel to any one of these planes. The "unit cell", the minimum unit for translation, is a rhombohedron
