| tensegrity and geodesic domes a tensegrity dome structure is a complex form in which the tensile and compressive members do not touch each other. it was buckminster fuller's claim that structures based on tensegrity technology could be used to build domes which could provide environmental control for entire cities. --- a geodesic dome structure is a type of structure shaped like a piece of a sphere or a ball. this structure is comprised of a complex network of triangles that form a roughly spherical surface. the more complex the network of triangles, the more closely the dome approximates the shape of a true sphere. the weight of these structures is distributed evenly throughout the series of triangles in the structure. they enclose the most amount of space with the least amount of material. since they have less area to lose heat from, they're also very energy-efficient. buckminster fuller invented the geodesic dome in the late 1940s to demonstrate some ideas about housing and energetic-synergetic geometry' which he had developed during WWII. this invention built on his two decade old quest to improve the housing of humanity. it represents a brilliant demonstration of his synergetics principles; and in the right circumstances it could solve some of the pressing housing problems of today (this housing crisis fuller predicted back in 1927). --- shelter systems' patented geotensict™ structures use both tensegrity and geodesic design principles. the advantages of geotensictm structures are high strength-to-weight ratio and simplicity that that is gained when tensegrity and geodesic construction are combined. shelter systems structures are tensegrity structures because the poles are not attached to each other except by the tension of the covering (ie, the poles would not stand without the covering). they are geodesic structures because the poles follow the shortest line on a sphere. geotensictm structures make possible the greatest strength to weight possible in a self supporting shelter. --- shelter systems bob gillis, owner of shelter systems and inventor of the grip clip tarp and tent fastener, has a long history of design in the tent industry, licensing tents to the north face, sierra designs, mountain hardware, marmot, and others. almost all of the backpacking tents using flexed poles that you see on the market are covered by bob gillis' patents. he has been granted 18 U.S. patents, from structural concepts to the molded clips used in the construction of shelter systems' dome, yurt, tent and greenhouse structures. shelter systems has consulted on many shelter and structure design projects: everest base camp, emergency relief shelter, folding shelter designed for the army, F22 tent. http://www.shelter-systems.com ---  make your own tensegrity model http://www.shelter-systems.com/tensegrity-model-making.html ---  how to draft a geodesic dome by spencer hunter http://www.uni.edu/darrow/new/geodesic/drawings/draft.html ---  what kind of applications for this technology would be suitable? an abstract on technology for designing tensegrity domes and spheres by robert burkhardt superstructures for embedded substructures allowing the substructures to escape terrestrial confines where this is useful (e.g. in congested or dangerous areas, urban areas, flood plains or irregular, delicate or rugged terrains). - economic large-scale protection of storage, archaeological, agricultural, construction or other sites. - refugee or hiking shelters. - frames over cities for environmental control, energy transformation and food production. - large-scale electrical or electromagnetic shielding. - exclusion or containment of flying animals or other objects. - spherical superstructures for space stations. - earthquake-resistant applications. these structures are extremely resilient and testing would very likely show they could withstand large structural shocks like earthquakes. thus, they would likely be desirable in areas where earthquakes are a problem. a pneumatic structure (fuller has characterized tensegrities as pneumatic structures) performed very well during recent earthquakes in japan. - low-environmental-impact shells for musical performances. - indoor/outdoor pavilions for trade shows etc. - supports to hold sunscreen protection for vulnerable amphibians. - watersheds to keep rain water from percolating through contaminated soils into groundwater, perhaps temporarily during in-situ remediation. - frames for hanging plants or other objects to dry. - pergola, trellis, or topiary framework. - micro-meteorite protection, sun-shielding for martian colonies. --- more about tensegrity solutions http://www.channel1.com/users/bobwb/prospect/prospect.htm ---  ------- monthly designboom newsletter ------- ------- ? comments and contact us ? ------- |
 a portable yurt dome next to a real mongolian yurt. they are quite similar to the mongolian yurts. both have a domed roof section over top of walls and the covering sections are shingled over each other.  domes have been to everest base camp many times over the years.  dome with extra strong translucent skylight windows instead of the clear vinyl windows  'yurt domes come complete with stakes, guy lines, vent tubes, spare parts and instruction manuals that detail floors, site selection, anchoring, cooling, winterizing, and stove installation...  how to divide the yurt dome into rooms - the double-layer type where an outer and an inner layer of tendons are inter-connected  portable greenhouses  shelter system's domes were used in a star trek episode  the first oval intention by robert gillis, later to be made by the north face. this structure started the geodesic backpacking tent revolution  lineup of earlier shelter systems tents  origami model |
