Open Design for Wood Structures

Open Design for Wood Structures

Masterthesis by Felix Dannecker

”Open Design for Wood Structures” consists of a  series  of strategies to  enable  anyone,  using  low-cost fabrication machines,  tomanufacture modular  interlocking  wooden elements without acquiring advanced  crafting  or technological  expertise.  The proposedapproach relies on two complementary steps: A method  to generate  cutting guides and  templates and  manufactured them  with  low-cost FDM  3d printers.  These  allow accurate  manufacturing of timber  joinery  on conventional wood-working machines. A workflow for the  design and  fabrication of reversibly  assembled  modular  structures  composed of timber  elements  with custom  joinery. Due to the highprecision required  to fabricate  with timber  joinery, such structures are usually produced  by highly skilled craftsmen  or by using advanced CNC manufacturing processes . As an alternative, Felix proposes a method  to analyze a given joint,  and based on a selected wood-working machine,  define the  relative  placement  between  the  tool and  the  timber  element  for cutting the required  shape.   The  positions  are  then  encoded  in a 3d printed cutting template, which allows a user to precisely place a wooden part on a woodworking  machines, allowing precise fabrication without need for advanced  wood-working skills.  A first iteration of the method  relied on creating cuttingguides to be used on a table  saw.  A second iteration, further  reduced  the  need for large tooling,  by replacing  the table  saw with ahand-held  mill.

Roto-Column - Design Optimization

RotoColumn- Design Optimization

Student research project by Janine Junen

COLUMN, in architecture, a vertical element, usually a rounded solid shaft with a capital and a base, which in most cases serves as a support. Concrete columns are key ingredients in the design of constructive systems in the building industry. In conventional manner the structural concrete columns are solid vertical elements. However, the hollow concrete columns can perform structurally similar to solid columns under compression while significantly reducing the weight and material consumption. This research is focusing on geometrical optimization of hollow concrete elements to maximize their structural performance.

In this project column forms are generated through tensioning tubular hyper-elastic membranes. The minimal surfaces are generated through internal compression rings from inside or tension the anchor points from outside of the membrane formwork.

Both geometric articulations are parameterized and subsequently optimized. Different optimization tools, such as, Galapagos, Oktapus, etc. are compared. The analysis of structural strength, deformation, displacement and form finding of the relaxed surface are all done in a real time process.

This research is bridging the gap between fully conventional design methods and fully digital driven procedures (e.g. Topological Optimization) for structural concrete columns and focusing on development of optimization tool for human-designed Roto-columns. In this procedure the design is preserved as a human activity with the aid of digital tools. The first stage of the design is driven by the material behavior of hyper-elastic membranes and fabrication constrains of  the Roto-Form technique.

RotoForm-Studio

RotoForm – Studio

In this studio participants designed and prototyped innovative concrete formwork systems that use resourceefficient strategies to make new shapes of concrete elements possible. The work is based on rotoforming concrete in hyperelastic membranes, a process developed by the Digital Design Unit (DDU) of the Technische Universität Darmstadt.

Rotoforming is a production process in which a minimal amount of liquid material is poured into a mould. The material is coats the wall of the slowly rotating formwork, but does not fill the entire mould. When used for casting concrete, the small amount of liquid material significantly reduces the hydrostatic pressure that acts on the formwork. The process thus unlocks a completely new range of resource efficient, lightweight formwork materials. We conceive of rotoforming as a material system in which form, material, structure and its synthesis (materialization, fabrication and assembly) are regarded as integral and closely linked elements. Computational tools and techniques, as part of this system, allow notating and instrumentalizing the intricate interactions between form, material, structure and environment within the architectural design process.

)( Co Forming examines interactions between bent boundaries for prestressing membranes. The membrane performs under tension while the boundary is a bending element in the system. In such an intricate equilibrium the membrane bends the boundary into a shape while the boundary prestresses the membrane. Together the systems form a complex cavity for casting and rotoforming.

The Roto_Column team produced a broad range of columns based on latex sleeves prestressed through internal compression elements and external tension elements. An adaptable jig allowed the team to quickly produce differently shapes columns.

Cube Space

Boyang Ji, Zhili Xia, Dawei Xin, Liangyan Xu

Cube Space combines a modular system von voxels with hyperboloid surfaces. Initial design explorations were conducted using arrays of wires to form hyperboloid surfaces. These quasi-surfaces were able to penetrate each other, similar to digital surface models. The aesthetically striking models, however, could not be translated into membrane formwork but were a good starting point to explore concepts of prestressing. When changing from wire to membrane the twelve edges of a cube and twelve diagonals on its six faces act as possible boundaries for prestressing membranes. A membrane hyperboloid is formed between two edges that are not coplanar. Within the rigorous spatial grid a multitude of shapes is possible. The resulting surfaces become the membrane formwork for rotoforming. The edges of the cube that were used as boundaries become part of the element. Similar to concrete-steel composite elements they allow for a precise connection detail between modules. The team explored the combinatorial potential of the cube space with simple translational operations such as copy, move, rotate and mirroring.

Dynamic Form(ing)

Shakeu Addallah, Danial Ahmad, Jianpeng Chen, Yijun Wang

Dynamic formwing is a membrane formwork system for a rotoforming process that is inspired by the concept of tensegrity. Tensegrity is a structural principle in which isolated compression members are connected through a network of tension elements such as cables or membranes. The intricate balance between tension and compression generates flexible and lightweight systems. The term tensegrity was coined by Buckminster Fuller and integrates the two words “tension” and “integrity”. Dynamic formwing exploits the concept by combining hyperelastic membranes with compression members to form cavities for casting liquid material and rotoform elements. Compression members become permanent parts of the cast to form composite building elements.

Form Follows Sequence

Liana Araklejan, Azra Licina, MarcelForberg

The idea of the project is based on the geometry of the invertible cube of the mathematician Paul Schatz. This geometry consists of two outer latch pieces and the middle belt part. The belt geometry consists of six sub-tetrahedrons, each with four surfaces and six edges. By arranging the tetrahedra at the connecting edges, the body can be rotated infinitely in one direction. The invertible cube is a rotoforming machine in its own right. Its infinite movement produces several rotoformed elements at the same time. The individual tetrahedron became the framework for our formwork systems. Three approaches can be pursued: The generation of volumes based on the entire tetrahedron, subtractive bodies, by using the edges of the tetrahedron as a frame to carry anchors of linear tension elements. In the project an initial weakness was turned into a major design feature: When prestressing a membrane in only one direction, drapery forms emerge. The team’s aim was to control and consciously design these shape in order to create the interesting contrast of a cast material having a textile appearance.

The Micro Factory

The Mirco Factory

The Design Studio “THE MICRO FACTORY” speculated about the design potential of buildings made from rotoformed concrete elements. Rotoforming is a production process in which a minimal amount of liquid material is poured into a mould made from hyperelastix prestressed membranes. The concrete coats the wall of the slowly rotating formwork, but does not fill the entire mould. Participants were invited to investigate the structural, constructional and architectural possibilities of designing and building with rotoformed constructions.

Students designed an E-Scooter Micro Factory. The design proposals deliver proposals for small scale, decentralized urban production. The E-Scooter Micro Factory repurposes a unused bunker in Frankfurt Hoechst from WW II. The bunker’s massive concrete structure form a strong contrast to the novel concrete elements made with rotoforming and membrane formwork. The group explored subtractive design procedures for the massive envelope and the lightweight re-design of the interior with an additive (rotoforming) approach.

RotoForm-Nodes

RotoForm – Nodes

by Samim Mehdizadeh and Prof. Oliver Tessmann

RotoForm is a procedure for the production of individualized form-active, hollow concrete building elements through a rotational casting, computational design and robot-aided fabrication. To rotoform an object, a small quantity of liquid material is cast into a mould that is then slowly rotated so that the material disperses along the mould surface. The material adheres to the formwork; an inner cavity emerges. This research exploits the significantly reduced hydrostatic pressure of the low amount of liquid material to unlock a new range of lightweight hyperelastic membranes as concrete formwork. The research yields a novel material system that consumes significantly less formwork material and less concrete. The research furthermore explores the morphological, visual and tactile performance provided by the minimal surfaces that emerge through prestressing (and not tailoring) the membranes and using them as a concrete formwork. The demonstrator of RotoForm Nodes uses the hollow objects as nodal connections of non standard space frames.
