#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona. Keep following us for more! A Method for Flat-pack Origami Construction of Spatial Structures: Yasushi Ishida (Cal Poly Pomona) and Trevor Stephen Lewis (Maffeis Engineering) "This project investigates origami as a means to construct 3-dimensional spatial structures in situ from pre-cut and pre-scribed flat sheet material composed of Aluminum. The approach relies on rationalizing a structure to origami node connectors connecting origami members. The method is intended to allow for efficient prefabricated construction of light-weight spatial structures."⠀ Learn more in the Conference Proceedings pgs 447 to 458. @yasushi_ishida * * * Ceramic Tensegrity: Shelby Orr, Logan Whitley - University of Illinois at Urbana-Champaign⠀ “The challenging part of a tensegrity structure is actually building it. Special joint connections are used to make this easier. The struts are designed as four arcs that snap into 3D printed connectors. The side connectors hold the arcs and a tensioning cable while the end connectors also contain part of a ball joint. The ceramic fiber of each strut is attached to half of a 3D printed ball joint that allows the end of the neighboring struts to easily screw into them for stability.” #throwbackthursday #structuralArt #structures #civilengineering #structuralengineering #architecture #design #creativedesign #pavilion #origami #tensegrity

(late) #tbt Here are two more research pavilions presented at #IASS2019 in Barcelona. Keep following us for more! ⠀ Polydon: an inflatable interactive polyhedron | Léo Demont - Dynamorphe "Inflatable-expandable structures are lightweight, easy to setup and can be made interactive with cables. Diodon Pavilion by Dynamorphe has previously investigated interactivity in architecture by the design and fabrication of an inflatable dynamic pavilion using an auxetic deployable semi-periodic folded membrane. Such a system allows local control of the surface metric, thus a variety of shapes could be attained. Ron Resch’s triangular deployable fold pattern used in Diodon allows a surface expansion of 66%."⠀ @dynamorphe * * *⠀ Knit Tensegrity Shell: Kenneth Tracy - Dynamic Assemblies Lab at Singapore University of Technology and Design "Tensegrity membrane shells are a new type of structural configuration in which tension and compression forces are resolved creating a stiff, free span structure. A first-of-its-kind prototype of this typology was built by students at Singapore University of Technology and Design in the summer of 2018. Ongoing research now explores the type’s potential at different scales, materiality and for varied applications. In particular applications and performance related to portability, aerodynamics and dynamic structural behaviour are being investigated."

#tbt Here are two research pavilions presented at #IASS2019 in Barcelona. Keep following us for more! ⠀ X-Shell: Mark Pauly – LGG EPFL "We present the X-Shell pavilion, a lightweight structure composed of elastic beam elements joined in a special layout that allows easy on-site deployment. The structure’s undeployed assembly configuration lies mostly flat and is easy to build, consisting of GFRP rods connected with mechanical fasteners made of aluminum and steel. The structure is deployed simply by either stretching the flat layout or by driving open the angles between rods at the joints. As the structure expands, the constraints imposed by the joints force its beams to bend and the whole structure buckles into its predetermined target shape." Learn more in the Conference Proceedings pgs 606 to 613.⠀ * * * Two Blue Shells: Lisa Ramsburg – schlaich bergermann partner “The resulting form, when inverted and placed on supports, is a unique spatial structure that highlights an opportunity to reuse plastic in a new way. The transparent material gently diffuses light; further study will reveal what interesting effects it might also have on climate and sound. The panels cast colorful shadows and illuminate moments of local and global curvature. The form of the pavilion integrates a modern experience defined by a very contemporary material with an acknowledgement of past forms, and in particular tiled roofs and shell structures found in and around Barcelona." Learn more in the Conference Proceedings pgs 493 to 500. @twoblueshells #throwbackthursday #structuralArt #structures #civilengineering #structuralengineering #architecture #design #creativedesign #pavilion

#tbt Here are two research pavilions presented at #IASS2019 in Barcelona. Follow us to see more in the upcoming weeks! Enneper Tensegrity Pavilion: Katherine A. Liapi - University of Patras “Minimal surface tensegrity networks (…) can be formed from the assembly of tensegrity units of square base. (…) a morphological investigation of various configurations of double layer-tensegrity networks of enneper shape was conducted with the utilization of the developed algorithm. The same algorithm is to be used during the construction process to determine all member dimensions and assembly values such as overlapping cable lengths. To facilitate the packaging, transportation and the on-site assembly of the structure, collapsible tensegrity units will be used.” This pavilion is further explained in the IASS 2019 Proceedings from pages 558 to 562.⠀ ⠀ ***⠀ ⠀ Thin Glass Pavilion: Sam Gregson - Eckersley O’Callaghan “The structure could be described as an active-bending structure in that initially flat elements are bent into their final form and this curved geometry gives stiffness to the final structure.”⠀ “Thin sheets of glass-fiber reinforced polymer (GFRP) are laminated between the thin glass ply at the edges of the glass panels. Adjacent panels are “zipped” together using sliding polymer zip pieces. This zip piece will transfer in-plane forces. Shear will be transferred using a bolted connection between GFRP sheets. Such a connection will allow for simple, rapid on-site construction.”⠀ ⠀ #throwbackthursday #structuralart #structures #civilengineering #structuralengineering #architecture #design #design #pavilion
