Within the brief of Reconsidering Elementarism, the researchers integrate different processes within architecture through computation. The aim is to develop a scalable, systemic and generative methodology, keeping the notion of universality intact.
This modular robotic assembly sweeps three dimensional spaces with ruled surfaces of third order during its inversion, which in turn is investigated to be woven by a multiphase weaving mechanism implanted within the machine.
The researchers saw neural interface as a new opportunity to make the user participant in the creation of ruled surfaces by controlling the spatial movement of the modular robotic assembly to be able to customize the individual shelters produced in real time.
STRUCTURAL ANALYSIS DONE BY DOF ENGINEERS
Composite Materials advantages: lightness with high mechanical properties, corrosion Resistance, termical and acoustic insulation, high damping capability, energy absorption capacity, design liberty.
Sections definition: the structure is simulated by frame elements of assigned section and shell elements with assigned Section Layer definition. The “Section layer definition” allow to perform non Linear analysis where the real behavior of composite elements is perfectly modeled. These analysis technique it is mandatory with composite elements, where each layer is made by a different material with great heterogeneity of properties.
Model definition: the structural model is composed by finite elements (shell and frame) placed accordingly with the architectural geometry. The loads assigned to the structure are: self-weight and wind internal pressure (0.2 kN/m2).
Loads have been combined in two main combination: SLS (service state combination) and ULS (ultimate state combination). Boundary conditions have been set around the zone bearing on ground.
Results: the FEM analysis performed show acceptable displacements of the structure under service combination (typically 50 mm all over the flat areas) and ULS stresses far beyond the material limit (typically 100 MPa).
It is relevant to underline that the geometric construction of this structure (ruled surfaces) produce performing “arch” surfaces where bending moments are relative small allowing for very light weight shells.
