#tbt Here is one more research pavilion presented at #IASS2019 in Barcelona! Continue following us for more pictures of the whole conference room setting, which was completely transformed in a day.⠀⠀ ⠀⠀ 1to3: Jan Brütting, Corentin Fivet - Structural Xploration Lab, EPFL⠀⠀ ⠀⠀ “Because of their large material mass and energy-intensive manufacturing, load-bearing systems contribute a large share of total building embodied energy and carbon (CO2). (…) recycling processes require energy and cause carbon emissions. Instead, we could reduce environmental impacts substantially if we design structures today that can be disassembled in the future and their parts reconfigured to fit a new purpose. ⠀⠀ We develop computational tools and fabrication methods to design and manufacture kit-of-parts structures whose members and connections can be assembled and reassembled in different configurations.”⠀⠀ ⠀⠀ The SXL team maximized the number of times stock elements could be reused in different structures, planning the reuse of bars and joints for 3 different structural settings.⠀⠀ ⠀⠀ “All three structures can serve a different purpose: 1) the shell, when covered, provides shade; 2) the tripod may serve as an exposition stand; 3) the column may be used as bar table and its overhanging part can be used to display information. This shows the potential of the proposed method to design multi-purpose, multiple-lifecycle structures.”⠀⠀ ⠀⠀ They built 2 of the 3 options at the conference in Barcelona. You can learn more about it in the SXL website https://buff.ly/2YdrSWU and in this video: https://vimeo.com/364621476 .⠀⠀ ⠀⠀ #shellstructure #reuse #multipurpose #discreteoptimization #optimisation #lifeCycleAssessment #kitOfParts #trowbackthursday #structure #structuralengineering #civilengineering #lightweight #architecture #design #creativedesign #geometryart

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona!⠀ ⠀ BeTA Pavilion: Diane Davis-Sikora - Kent State University⠀ #Biotensegrity Textile Assemblies: “Born in art, the #tensegrity logics has been advanced in disciplines from architecture and human anatomy. Biotensegrity principles introduce an adaptive, ‘living’ structural model characterized by networks of interconnected components and tendons with a shape #adaptive capacity. Bending-active is an approach to form force equilibria that adopts actively curving beams and surfaces within their elastic ranges. BeTA Pavilion explores the formal opportunities of biotensegrity logics using elastically bent glass fiber reinforced plastic rods and CNC knitted textiles. Its bending-active systems (inspired by vertebrae typologies) is comprised of pre-stressed and self-stabilized tetrahedron modules that are arrayed and sequenced to produce structural equilibrium with a bandwidth of dynamic motion.”⠀ ⠀ * * * ⠀ ⠀ Common Multiple: Mitja Bukovec and Katharina Scharler - Technical Univerisity Graz⠀ “The aim was to develop a visually appealing, low tech, earthquake resistant, #lightweight structure. The structure focuses on using wooden stripes with minimal cross-sections and a textile #membrane to stabilise its shape. A series of case studies resulted in maximum utilisation of material properties to minimise material thickness and the cross-sections. The structure is adaptable to a variety of materials – as long as they fulfil specific requirements, the system can be built with the resources available locally. The pavilion uses wooden veneer, fabric and greyboard. The #minimal material thickness and the simple push-fit system simplifies the assembly process of the lightweight structure. (…) By defining a few parameters in an #algorithmic model, the user can quickly adapt the structure.” Learn more in the Conf. Proceedings pgs 467 to 474. ⠀ ⠀ #BendingActive #glassfiber #knittedtextiles #sustainability #earthquakedesign #lowtech #throwbackthursday #structures #civilengineering #structuralengineering #lightweight #architecture #design #creativedesign #geometry #geometryart #shellstructure

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona!⠀ ⠀ The Infinite Line: Modular Active-bending Pavilion - Vernelle A. A. Noel at Georgia Institute of Technology⠀ “The ‘Infinite Line’ Pavilion is a lightweight, fiberglass structure that grew out of investigations into the design and fabrication of a pavilion built on wire-bending techniques specific to the Trinidad and Tobago Carnival. (…) The design chosen was created by forming three ‘pringle’ shapes (…). Each pringle intersected the other so that an equilateral triangle was formed at their bases and tops, and nodes along the sides.” Their next steps will include textile to aid prediction and control of the structural behavior of the pavilion. ⠀ Learn more in the Conference Proceedings pgs 574 to 581.⠀ @vernelleaanoel ⠀ * * * Mortar space truss pavilion with robotic extrusion: Romain Duballet - Laboratoire NAVIER, Ecole des Ponts⠀ “The printing process consists in fabricating EPS blocks with a hot wire cutting process and then to progressively assemble them so they can support the mortar extrusion. Once assembled, the blocks also protect the curing mortar. The mortar being printed on the blocks, it progressively acquires mechanical strength and becomes able to bear its own weight as well as the additional matter above. Yet the blocks support the printing, reducing the need for early age resistance for the mortar.” ⠀ Learn more in the Conf.

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona!⠀⠀ ⠀ Al-becular: Vittoria Laghi - University of Bologna, Italy⠀ “The logic of the Al-becular pavilion is to meet halfway between the advantages of additive fabrication and serial industrially-produced elements for structural design. Given the initial constraints of the brief in terms of portability and weight, the choice fell on a volumetric network structure paradigm. The nodes, being the most articulated geometry, are meant to be fabricated with Additive Manufacturing technology, thus, minimizing the joints and facilitating the assembly/disassembly process. (…) The geometric model starts from three polyhedral arranged in a tripod. This initial thin-line schematic is topologically maintained but anisotropically adapted to maximize its span within the given 4 x 4 meters area, thus generating an overall slightly asymmetric shape.”⠀ @ale2x72 ⠀ * * *⠀ ⠀ Gyroid Minimal Surface in Weaving Structure: Weixin Huang - Tsinghua University⠀ “The #weaving structure is an #activebending structural system proposed by our team for construction of free form #gridshell. Through the #formfinding mechanism of the interwoven rods, the weaving structure system can be used for construction of a great variety of #freeform geometries only by off-the-shelf rods and uniformed joints, and without using complex CNC or 3d printing machines. The generative algorithm based on remeshing guarantees its adaptation to various double curved surfaces. Our proposal for the IASS2019 (…) is to build a #gyroid minimal surface within a volume of 4m diameter sphere by the weaving structure system. A comparatively denser weaving grid is used to improve the structural performance.”⠀ ⠀ ⠀ #throwbackthursday #structures #civilengineering #structuralengineering #architecture #design #creativedesign #geometry #geometryart #shellstructure

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona!⠀ ⠀ Deployable Tensegrity Pavilion with Inflatable Struts: Jonathan Dessi-Olive - UC+GT⠀ ⠀ “Tensegrity structures are considered to be one of the most efficient forms of construction because they maintain their stability with the fewest number of structural members carrying purely axial forces. (…) . This research addresses a critical issue of the difficulty to build tensegrity structures at large-scale through advancements in an active-deployed #tensegrity structures system that integrates its deploying mechanism directly into the compression members. Replacing rigid compression struts with low-pressure #pneumatic members presents an opportunity to build a minimum weight structure with significant global volume change.” @jdessiolive @gtarchitecture @uzuncase ⠀ Learn more in the Conference Proceedings pgs 582 to 589.⠀ ⠀ * * * ⠀ ⠀ Compact Foldable Reusable Portable Canopy: Tomohiro Tachi - University of Tokyo ⠀ ⠀ “We designed this foldable #canopy based on a rigidly foldable #origami with quadrilateral panels. Kinematically, the structure can be continuously deployed from a flat-folded state to the 3D state in a one-DOF motion. The deployed state forms a part of a torus; this structure is intended to be a module that can be combined to make a variety of partially or fully closed surfaces.⠀ (…) Specifically, the structure is assembled from multiple developable parts tied together by strings based on traditional bookbinding techniques. Each developable part is fabricated in a flat state, where rigid panels are made of 1mm carbon fiber reinforced plastics and the repeatedly foldable hinges are made by patterning a thin silicone matrix that creates a gap between rigid panels. The structure has a total mass of 20kg and can be carried and deployed by two or three persons within a minute.” ⠀ Learn more in the Conf.

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona! SmartShell: Ding Wen ‘Nic’ Bao and Xin Yan- RMIT University “#SmartShell is a research project which addresses innovation in building structural components through the generative design technique #BESO and the application of #FDM robotic printing to produce efficient and low-cost large span spatial lightweight structures. (…) The innovative methodologies of production, construction and assembling are to ultimately replace welded, forged and cast components by large robotic 3D printed components with a new script developed in RMIT University and bolting methods. The advantages of the new design process are less labour, less joint nodes, shorter assembling process, lower cost & more efficient material usage and more complex & elegant large structural form. The research project is also part of the large research topic of robotic design for mass customised manufacturing, being undertaken by the authors.” Learn more in the Conf. Proceedings pgs 485 to 492. @nic_bao * * * Quipustructure: Manuel Espinoza - Ricardo Palma University “The #Quipustructure Project goal is to create a #tensegrity system based on Inca’s ancient lightweight construction technology. The use of local materials like #bamboo and #junco rope combined with the braiding techniques developed by the #Incas have demonstrated great structural performance with a low carbon footprint. (…) This prototype has been developed according to tests and loads analysis to achieve better structural behavior. The use of reed and bamboo on the project generates a low environmental impact and reduces manufacturing and transport costs. On the cultural level, the project gives the ancient Andean communities the opportunity to teach ancestral techniques and constructive philosophy to be used on the fabrication of modular lightweight and #deployable structures.” Learn more in the Conf.

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona!⠀⠀ ⠀ FlexMaps Pavillion: Francesco Laccone - ISTI-CNR and DESTEC - University of Pisa⠀ “Bending-active structures are able to efficiently produce complex curved shapes starting from flat panels. The desired deformation of the panels derives from the proper selection of their elastic properties. Optimized panels, called FlexMaps, are designed such that, once they are bent and assembled, the resulting static equilibrium configuration matches a desired input 3Dshape. The FlexMaps elastic properties are controlled by locally varying spiraling geometric mesostructures (...). the project of a lightweight plywood pavilion named FlexMaps Pavilion is a single-layer piecewise twisted arc that fits a bounding box of 3.90 x 3.96 x 3.25meters.” Learn more in the Conference Proceedings pgs 509 to 515.⠀ ⠀ Tribute to Kenneth Snelson: Andrea Micheletti from the Tor Vergata Tensegrities team at University of Rome Tor Vergata⠀ “This pavilion is dedicated to the memory of Kenneth Snelson (1927-2016), the American artist who built tensegrity sculptures/structures worldwide. (...) As Snelson explained in his picture essay, “Tensegrity, Weaving and the Binary World”, X-Modules can be combined together in space-filling assemblies which can be extended to any length in all directions. The shape of the pavilion is that of a ‘gate’, and it is obtained by laying the X-Form on the top face and the two opposite lateral faces of a cube, so that when walking through such structure, one can observe on the sides and above the transparent tensegrity arrangement of struts and cables. The pavilion is composed by 88 struts, forming 44 X-Modules, and a multitude of cables. The structure is supported on the ground at four pairs of points, corresponding to the sides of four X-Modules.” Learn more in the Conference Proceedings pgs 598 to 605.⠀ ⠀ #throwbackthursday #structuralArt #structures #civilengineering #structuralengineering #architecture #design #creativedesign #pavilion #geometry #geometryart #shellstructure #tensegrity #xform #formfinding #bendingActive #formfinding #plywoodCNC

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona.⠀ ⠀ Radiolaria Pavilion - BoSheng Liu at the University of Louisiana at Lafayette⠀ “In this work, the authors aim to contribute to the exploration of the rolling assembly method in lightweight bending-active structures by investigating the design strategy based on a biomimetic investigation of the natural cellular structures, using engineered fiberglass sheet material in mass customization of components. The anatomy and cellular morphology of radiolaria were studied, and the morphological attributes were implemented within the design loop process. Furthermore, the designed lightweight fiberglass structure required no formwork or molding through the employment of the bending-active method. This research utilized a sophisticated, holistic design process integrating digital fabrication capability with formative feedback from structural analysis using finite element analysis(FEA).” ⠀ Learn more in the Conference Proceedings pgs 543 to 547.⠀ ⠀ * * * ⠀ ⠀ Corn Flips: Tonia Ludwig and Hannah Melzer at TU Graz⠀ “The main structure of the presented design is made of corn starch flips, which are commonly used as packaging material. Providing a design with bio-degradability and light weight material with the effect of self-adhesiveness led to this new material. The flips will be attached to prefabricated components by moisture only. Positive side effects besides the biological aspects, are the transportation and construction. Breaking down the light-weight structure into smaller panels, makes it easy for transportation and setup. The corn starch flips provide the design with an uncomplicated design and construction feature for free form structures.” ⠀ Learn more in the Conference Proceedings pgs 563 to 567.⠀ ⠀ #throwbackthursday #structuralArt #structures #civilengineering #structuralengineering #architecture #design #creativedesign #pavilion #geometry #BendingActive #fiberglass #catenaryform #biometric #cellularStructure #bioDegradability #sustainability #vaultedceiling #geometryart #shellstructure

#tbt Here are two more research pavilions presented at #IASS2019 in Barcelona. Keep following us for more!⠀⠀ X-Mesh: Xavier Tellier at Ecole des Ponts ParisTech⠀ “X-Mesh is a pavilion that demonstrates a new rationalization strategy. Its structure, composed of a hexagonal grid of beams and cladding panels, is based on a geometry that rationalizes connections at two levels: firstly, nodes are repetitive, only two types of nodes are used. Secondly, panels can easily be connected to the support beams as they are orthogonal to each other. We prove that the proposed geometrical configuration can be asymptotically built on a smooth surface.” Learn more in the Conference Proceedings pgs 516 to 523.⠀ #thinkshell @designbydata⠀ * * * ⠀ ⠀ Push Puppet: Jana Rieth at Graz University of Technology⠀ “An adaptive structure was chosen for the pavilion design due to its ability to react to variable conditions while increasing the material effectivity, which in turn leads to a weight reduction. The nineteen aligned arches are consisting of fifteen prefabricated modules, which are connected by a pretension cable. The adjustable modules generate the appropriate shape for the internal and external influences. (…) In this research, it has been shown that it is possible to design and develop a practical solution with relatively limited resources, which is lightweight and contains an intelligent, adaptable load-bearing system.” Learn more in the Conference Proceedings pgs 459 to 466.⠀ ⠀ ⠀ #throwbackthursday #structuralArt #structures #civilengineering #structuralengineering #architecture #design #creativedesign #pavilion #geometry #deployable #structuralmorphology #deployablestructure #kineticarchitecture #activegeometry #parametricdesign #conceptualdesign #formfinding #optimization #adaptivegeometry #actuators #architecturalgeometry #gridshell

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

#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."

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."

#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
