Lionel:

Read here about issues of scale and how they relate to tensegrity.

=Micro-scale Tensegrity=

==Electron Beam and Spectra fibers==

3D printing of micro-scale tensegrity structures was done by using electron beam melting in Ti6Al4V titanium alloy. The structure had temporary supports that were post-tensioned employing Spectraâ fibers [2].

==Micro-stereolitography with Swelling Gels==

3D printing of micro-scale tensegrity structures has been proposed by using a projection micro-stereolitography (PμSL) system [3], an additive fabrication technique based on a photo polymerization reaction. Liquid polymer resin is photo-chemically converted into a solid 3-D micro-structure in a layer-by-layer fashion. PmSL allows the use of swelling gels that, when dried, contract and create the necessary prestress [1].

=Fractal Tensegrity=

Tensegrity can be implemented on multiple scales in a single structure in a fractal implementation.

R. Buckminster Fuller proposed such an iterative process in his work on tensegrity. Keeping in mind that "there are no solids in structures, ergo no solids in Universe." Fuller considered the typical tensegrity, composed of struts and tendons, and imagined substituting for any individual strut in the tensegrity, another tensegrity, and so on. In his words:

The tensegrity masts can be substituted for the individual (so-called solid) struts in the tensegrity spheres. In each one of the separate tensegrity masts, acting as struts, in the tensegrity spheres it can be seen that there are little (so-called) solid struts. A miniature tensegrity mast may be substituted for each of those solid struts. The subminiature tensegrity mast within the tensegrity struts of the tensegrity struts of the tensegrity sphere and a subsubminiature tensegrity mast may be substituted for each of those solid struts, and so on to subsubsubminiature tensegrities until we finally get down to the size of the atom and this becomes completely compatible with the atom for the atom is tensegrity and there are no "solids" left in the entire structural system. There are no solids in structures, ergo no solids in Universe. There is nothing incompatible with what we may see as solid at the visual level and what we are finding out to be the structural relationships in nuclear physics.

[[file:Fuller Tensegrity Fractal Syn 740.21.png|thumb|500px|none]]

=Part/Whole Relations=

Tensegrity, by its very nature, requires consideration of the relationship of a whole to its parts. This whole/part consideration implies one level of scale, or order of magnitude: the whole is an order of magnitude above the parts.

The whole is simply the structure considered as one, single unit. In a classic tensegrity structure, the whole is characterized by structural integrity instantiated by [[prestress]] and [[stiffness]]. The parts of this whole are conventionally divided into local islands of [[compression]] [[Strut|struts]] joined by global, interconnected networks of [[tension]] [[tendon|tendons]].

MOOM Pavillion

2022-05-15T16:14:15Z

Lionel: Added category = Japan

Read here about the MOOM pavillion, a tensegrity [[membrane]] structure erected in Noda, Japan.

=Description=
Designed by C+A Coelacanth and Associates, and called the "MOOM tensegritic membrane structure."

In Noda, a city located in the far northwestern corner of Chiba Prefecture, Japan, one of the partners of C+A coelacanth and associates, Kazuhiro Kojima, led a team of 70 architectural students at the Tokyo University of Science in the design and creation of an experimental, lightweight, load-bearing structure for a temporary pavilion. The 26-meter long, up to 7.5-meter-wide and 4.25-meter-high volume is self-supporting and is comprised of solely two components: metal nodes and a delicate elastic polyester skin, only 0.7-mm thick. The airy structure was erected in one day, using a tectonic system of a membrane is pulled over aluminum tubes that create a tensegrity system. The 131 bars are various lengths and do not touch, opting to create a synthesis of skin and structure via a system of sewn-on sheaths that the structural modules slide into.

The structure is not completely self-structuring, and relies on gound-based anchors, altered aluminum tubes used as pegs.

The total form weighs a mere 600 kg, however it covers a ground area of 146 square meters. Since the membrane screens off 80% of the UV radiation, but allows 50% of the daylight to pass through, the softly filtered light creates a fascinating spatial impression internally. When illuminated, the translucent pavilion has the appearance of a lighted sculpture. The pavilion admits an ample amount of daylight while pointedly shielding from UV radiation; the effect is one of ethereality, tectonically manifested as a swathe of diffused light. at night, the relationship of node and skin reverses and the nodes create a pattern of fractured ribbing.

99 Failures Pavilion by University of Tokyo

2022-05-15T16:11:03Z

Lionel: Added category = Japan

Read here about a pavilion built on tensegrity principles by the University of Tokyo.

=Overview=
The pavilion was conceived in October 2012 at the University of Tokyo Graduate School of Department of Architecture and Architectural Engineering Yusuke Obuchi laboratory and Atsushi Sato laboratory. The Obayashi Corporation, whose fabrication shops are located near the Toyota Motor factory, played a key role in the implementation.

=Photos=

[[file:99Failures Title 20131118.jpg]]
caption="Title Page for Ninety Nine Failures Pavilion, University of Tokyo, December 2013."
link="99 Failures Pavilion Photo Gallery"

For an extensive collection of photos, see the [[99 Failures Pavilion Photo Gallery|99 Failures Photo Gallery page]] .

=Details=
The project was named "Ninety Nine Failures" in a nod to acknowledging the role of failure in urban design. With this name the designers paid homage to the role of failure in exploratory design. In the design process, the designers repeatedly tested different structural models to find a geometry that could smoothly transition from a flat, two-dimensional surface into a sturdy 3D form.

The compression strut is based on a perpendicular "X" form, rounded out into a pillow shape. Each metal component was carefully spaced apart to allow light to pass through and to minimize the impact of wind loads.

Digital mockups were created in Grasshopper and Kangaroo to simulate the tensegrity model and assembly process.

The designers are built a physical 1:3 model from laser cut materials to study the behaviors of the tensegrity test the tension cables. This model tested the accuracy of the structural simulations. The process of assembly remained the same as our last model, with multiple marionette ropes to hoist the entire structure in one go. The structural simulations turned out to be a lot more complicated than expected, and the structural engineers from Obayashi Co. were critical to the success of the project. In addition to material research in computational fabrications, the team experimented and fine-tuned the assembly system. Instead of putting the components on site piece by piece, all of them are linked together to create a 2D surface first and then lifted with a series of cables to form a 3D shell structure. The assembly process is analogous to the way marionette puppets are manipulated by a handheld frame, suspending the puppet by threads.

Prestressed cables pull together layers of thin stainless steel sheets welded together and inflated with hydraulic pressure to create the shape of inflated metal pillows. The task of attaching the cables proved particularly challenging due to the bulk of the assembly and stiffness of the components and cables.

After the materials were assembled on site, a crane pulled the structure upright into its final form.

The pavilion stood outside the University of Tokyo Digital Fabrication Lab at the end of 2013.

本研究は、自由曲面のテンセグリティ構造を2次元からの立体化により安定化させる構法のケーススタディとして、2012年10月から2013年12月までに東京大学大学院建築学専攻小渕祐介研究室（以下、小渕研）、同佐藤淳研究室（以下、佐藤研）と株式会社大林組（以下、大林）との協働にて仮設パビリオンの設計、プロトタイプ製作を行い、その成果をまとめたものである。部材加工・制作にはAnS Studio・竹中司氏の協力を得た。
本研究のケーススタディにおいては、パビリオンの設計及び施工検討にあたって導入された諸情報技術によりもたらされる1．設計プロセス　2．施工方法　3．建築構造のそれぞれにおける革新性という観点から、本研究の成果と付随する問題点を検証し、その発展可能性を考察した。

背景および目的

20世紀初頭以来、現在に至るまで国際的な枠組みの中で確立されてきた近現代の建築生産システムは、2次元の図面の組み合わせによる指示を基本とする、直行系の座標を持ったモジュールに従い確立されてきた。

一方で、フライ・オットーが1982年の自著の中で「今日の目標は自然な建物と都市をつくることである―中略―人間とその技術が自然と不可分であるような状態を作り上げることである」と述べていることに顕著だが、自然の持つ合理性を取り込むことを目的とした3次元的な曲線・曲面を基調とした有機的な建築への取り組みは、1960年代以降徐々にその例を増やし、現代では90年代後半以降の情報技術の飛躍的革新の支えを得て、一定量の事例を蓄積するに至っている。

しかしながら、3次元的な曲面を構成する建築部材の生産システム及びその施工過程は、依然として非常に煩雑な生産過程や大量の仮設資材を必要とするケースや、膨大な図面による建築形状の指示に基づく職人の手作業等を必要とするケースも多く、特に経済的な観点から十分に合理的な生産過程や構法の確立には至っていないのが現状と言える。

本研究では、これらの問題意識に基づき、従来の建築生産システムにおける技術体系で十分に対応可能な2次元の情報で部材形状を定義し、かつ組み上げまでを平面上で行うことで煩雑な生産や仮設構造を回避しながら、簡易な施工過程のみにより3次元形状を生み出し、成果物としては有機的な曲面のもつ合理性を獲得することを目的とした。

Bragdon, Claude

2022-05-15T15:34:24Z

Lionel: /* Geometry */ typo on octahedra

Read here about Claude Bragdon, an American architect who influenced Buckminster Fuller and so, in turn, had an influence on the discovery of tensegrity.

=Overview=

Claude Fayette Bragdon (August 1, 1866 – 1946) was an American architect, writer, and stage designer based in Rochester, New York, up to World War I, then in New York City. His books on democracy, fourth dimensional geometry, mystical thought and Yoga were well known in the Eastern United States and influenced Fuller.

He was a highly infuluential architect, whose name faded when modernist architecture gained sway, partially at his expense.

=Geometry=

Bragdon's work often featured detailed, accurate perspective renditions of the platonic solids: tetrahedra, octahedra, icosahedra, and other higher-ordered forms. His focus in his work on the fourth dimension was in spatial projection, usually in order to generate sumptuary ornamentation for the built environment. The ornaments could be attached to existing structures like skin on bone. Fuller, on the contrary, sought new structural arrangements that would emerge from such geometrical constructs. Their form itself was the structure.

Bragdon's interest in the fourth dimension had spiritual overtones, and he often spoke in metaphors comparing our inability to sense more than three dimensions with notions of higher yet inaccessible states of consciousness.

[[file:hall of octa dodeca frozen 1932.jpg|thumb|500px|none|A woman stands between two icosahedra, in the background a two frequency icosahedron is drawn, the pattern that is the basis of the geodesic dome.]]

[[file:Platonic Solids and Sinbad, Frozen Fountain 1932.PNG|thumb|500px|none|Bragdon popularized the platonic solids at a time when squares, cubes and rectangles dominated architecture.]]

[[file:Regular Polyhedroids, Frozen 1932.PNG|thumb|500px|none|Bragdon explored variations and projects of the classic geometric figures.]]

Bragdon's focus on ornament would become the weapon used against him, Sullivan and others as more severe modernist anti-ornamental styles took hold.

=Evidence of Influence on Fuller=

Fuller read Bragdon's 1918 book, "Architecture and Democracy," in 1927 as indicated in the list references he wrote in 1928. In Bragdon Fuller found expression of many of aspects of his vision for industrially produced, efficient housing. Here are a few quotes from the work:

"[T]here is no inherent reason why the bones of a building should not be devised by one man and its fleshly clothing by another..." p. 11
"Science advances facing backward, so what prevision can it have of a miraculous and divinely inspired future—or for the matter of that, of any future at all?" p. 57
