RESULTS

A developed concept for a performative building system was brought for a one week working session with selected participants for refinement and building a full-scale prototype. The system foundation roots in a computational design approach oriented towards a lightweight and multiscalar application based on material performance enhanced by the hygroscopic properties of wood. The strip pattern adopted for this purpose allows to design and construct artifacts  from a paper model to a large scale structure, with the potential to be applied on a building scale.

ASSEMBLY STRIP STRATEGIES

Stripe patterns are widely spread in nature in different scales, from the smallest molecules to skin pattern of plants and animals.

The generation and the properties of such structures are explored through parametric techniques using algorithms to create complex hyperbolic geometries. Strip surface discretization can be used to represent three-dimensional objects defining space, form, and structure simultaneously. They are intensively adopted in various fields of construction, like boat industry, concrete formworks, panelling techniques among many others. While in architecture, material elements can be defined by behaviour rather than shape, arising new performative potential through the material driven design approach.

Architectural contextualisation lays in the design development of a multi-column structure which merges and accommodates various architectural archetypes, showcasing a smooth curved surface carrying topological interrelation between the off-grid vertical elements.

In the generation of the hyperbolic overall geometry, a globally continuous strip pattern emerges, defined by the equilibrium state of the embedded forces. The strip behaviour takes advantage of algorithms for geometrical planarization and developability in order to introduce a simple assembly strategy of complex geometries from initially planar plywood pieces.

On the local level, based on the ring like typology and its active-bending principle, the resulted structure acquired strong self-supporting capacity increased by the double curvature within the global shape. Grain direction, material size available on market and cnc machining cutting space were embedded in the computational model as active design drivers to define the strip dimensions.

The average strip length and the temporarily augmented state of flexion gained through the material hygroscopic properties have determined the assembly time. The edgewise connections were developed in order to allow an easy and fast assembly and disassembly on-site process, arranged to be feasible for a reduced amount of people without risk of damage. The entire digital fabrication workflow was designed estimating the time of production to run parallelly with the assembly within only three days.

A self-standing lightweight rigid structure entirely built in thin plywood, three metres high with a span of six metres went through steps from design to production based on a computational model which integrates material performance, structural analysis including fabrication and assembly stages. The structure covers around 13.7 m² with a total weight of less than 70 kg.

BRIEF

Stripe patterns are widely spread in nature in different scales, from the smallest molecules to skin pattern of plants and animals.These patterns can also be identified in the growth of cells, which show how their intensification in specified areas makes the surface transform and curl on itself. The generation and the properties of such structures are explored through parametric techniques using algorithms to create complex. In depth, from a spatial point of view, stripe surface discretization can be used to represent three-dimensional objects defining space, form, and structure simultaneously. They are intensively adopted in various fields of construction, like boat industry, concrete formworks, panelling techniques among many others. While in computational design, material elements can be defined by behaviour rather than shape, arising new performative potential through the material driven design.
The proposed system will focus on synthesizing stripe patterns from double curved surfaces, giving the user the possibility to define the design of a new global geometry and vary parameters like stripe orientation and line spacing. The computation of the design process will embedmaterial properties of wood, considering it’s elastic moment and using it as an advantage to increase the global strength of the lightweight system. Physical properties and material behaviour will be computed and simulated throughout the process and will be the foundation for the actual construction technique on siteand further on for the assembly strategy of complex geometries from initially planar plywood pieces.
The structure will be dictated by a ring like topology and will include dedicated joint connection between the stripes, distributing topological differentiation by interconnecting areas. The resulting patterns are globally continuous, investigating the possibility of a smooth spacedefined by the equilibrium state of the embedded forces.


GOALS

Among the learning process of computational and parametric design, this workshop is oriented towards the digital fabrication strategies and an integrative design thinking. Workshop sessions will include material properties research, development of complex geometrical 3D parametric models, fabrication details and techniques, work with small scale prototypes with the help of a laser cutter and 1:1 prototypes with the use of a CNC machine. In order to test the performative capacity of the material and the integration of all the principles mentioned above, an architectural prototype will be realised in scale 1:1.
