the institute for computational design (ICD) and the institute of building structures and structural design (ITKE) continue their series of research pavilions with the 2014-15 edition at the university of stuttgart. the design and building method is based on the nest construction of the water spider — a species which spends most of its life underwater, for which it constructs a reinforced air bubble to survive.

 

initially, the spider builds a horizontal sheet web, under which the air bubble is placed, finally sequentially reinforcing it by laying a hierarchical arrangement of fibers from within. the result is a safe and stable habitat that can withstand harsh natural elements. this natural production process shows how adaptive fabrication strategies can be utilized to create efficient fiber-reinforced structures. for the ICD/ITKE research pavilion 2014-15, the team examined this construction process, analyzing, abstracting and transferring the behavioral patterns into a technological fabrication process.

for the application of this biological system into a building construction, a process was developed in which an industrial robot is placed within an air supported membrane envelope made of EFTE. the initially flexible formwork is gradually stiffened into a self-supporting structure by reinforcing it with carbon fibers from the inside, selectively applied where necessary. the resulting shell forms a habitable pavilion with unique architectural qualities, while at the same time being a highly material-efficient structure.

at the early stages of the construction process, the shell geometry and main fiber bundle locations have been generated by a computational form finding method. this strategy allows the designer to navigate and integrate various structural parameters into performative fiber orientations and densities.

 

corresponding to this, a prototypical robotic fabrication process was developed for carbon fiber reinforcement on the inside of the flexible membrane. the changing stiffness of the pneumatic formwork and the resulting fluctuations pose a particular challenge to the robot control. in order to adapt to these parameters, the current position and contact force is recorded through an embedded sensor system and integrated into the robot in real time, allowing for constant feedback between the actual production conditions and the digital generation of control codes.

the ICD/ITKE research pavilion 2014-15 demonstrates the potential of a novel building method through advanced computational design, simulation and manufacturing techniques. the result is not only a particularly material-effective construction, but also an innovative and dynamic architectural example.
