Pavilion / EmTech (AA) + ETH

Today we are bringing you international student pavilion collaboration between the AA and the Swiss Federal Institute of Technology (ETH).  The project had students and professionals contributing from multiple disciplines to allow this project to come to fruition, from structural analysis, sun shading studies, design, and fabrication.  The collaboration brought about an advanced study into creating structure through the manipulation of single sheets of plywood to create a temporary light construction.  Check out more after the jump!

“Out of a collaboration between the Emergent Technologies and Design program (EmTech) of the Architectural Association (AA), London, and the Chair of Structural Design at the Swiss Federal Institute of Technology (ETH), Zurich, a temporary light timber construction has been designed that functions as sun shading for parts of the grand stairs in front of the architecture department of the ETH. Based on bending behavior under the self-weight of over-sized sheets of plywood of up to 11 x 2.5 m, the design activates the material properties as the defining element in the transfer of forces. More images and architects’ description after the break.

Based on a systematic investigation into the defining parameters, sheets of 18 mm thickness with fibers mainly in longitudinal direction have been used for the pavilion. Cuts within the sheets influence the bending resistance of the sheets, enable a larger spatial enclosure and reduced wind load acting upon the structure, and additionally produces a shadow pattern on the stairs that are used as seating area during summer time. Varying the length of the sheets generates small variations of the bending curve that have been utilized for the overlapping and interlocking of adjacent elements resulting in a system of self-stabilizing vaults. The vaults are cross-braced by a sequence of cables. These cables distribute all other load conditions evenly within the edge strips, and so reduce additional deformation of the arched form to a minimum.

The design refinement as well as details of the construction and fabrication process of the pavilion have been worked out by a design team of EmTech-students. The initial design idea derived from the winning entry of a competition team during an internal design competition within EmTech. In addition, the work of the design team has been informed by material test and design studies conducted during a workshop of all EmTech students at the ETH.

In general, precedents to this field of work commence with the work of Alvar Aalto and Charles Eames in plywood, and the techniques of scoring, cutting and bending to achieve curvature have been established in a variety of materials in jewelry design, surface ornamentation, paper and other craft practices, as well as in airplanes and boats. Recent contributions include Skylar Tibbits’ Surface Ornamentation at the MIT – Massachusetts Institute of Technology (2008), and The Probotics of the AA DRL – Architectural Association Design Research Laboratory (2010).”
