John Harding to present Trada pavilion at IASS 2013

John Harding of the RCD team will be presenting our work on the Trada pavilion at the International Associate for Shell and Spatial Structures symposium in Wroclaw, Poland on the 23rd September 2013. The talk, simply titled The TRADA Pavilion – A Timber Plate Funicular Shell will be given as part of the session dedicated to Structural Morphology – Faceted and origami structures.

Searching for Innovation and Elegance in Complex Forms paper presented at Prototyping Architecture 2013

Harri Lewis and Stephen Melville of the Ramboll Computational Design team presented their paper ‘ TRADA Pavilion – Searching for Innovation and Elegance in Complex Forms Supported by Physical and Software Prototyping’ (authors Harri Lewis, Stephen Melville and John Harding) at the the Prototyping Architecture conference at the Building Centre, London. An e-book of the conference papers can be downloaded here

Trada pavilion exhibited at the Prototyping Architecture Exhibition 2012

A full size trial erection of one of the plywood timber legs of the Trada Expo pavilion will be exhibited at the Prototyping Architecture Exhibition in Nottingham starting 17th October.

The trial was undertaken to test the stiffness of the reciprocal support panels, the ease of erection, quality of finish and the effect of adding edge stiffeners upon the overall performance of the structure under accidental load. It proved an extremely useful exercise, validating the time and effort expended in ordering and building the test leg. It will be accompanied in the exhibition by a 1:10 scale model of the pavilion, built to assess the potential modes of failure.

Trada Pavilion

Ramboll’s Trada Pavilion, a plywood structure inspired by the efficient curved forms of Frei Otto and Heinz Isler, was unveiled to the public for the first time this week at the Timber Expo 2012. The exhibition is the premier show in the UK for all those involved in the timber sector.

Trada commissioned Ramboll’s computational design team to design the timber pavilion, which was the focal point of the Timber Expo 2012 stand and one of the biggest draws at the exhibition. After this exhibition, the sculpture will showcased again on TRADA’s stand at the 2013 Ecobuild exhibition.

The team set themselves the challenge of creating a planar three-valent mesh approach for the double curved surface, rather than the conventional triangular mesh. A hexagonal mesh has the advantage of fewer connections and greater structural efficiency, but requires coding from scratch and a great deal of research. The final design utilizes techniques from the computer game industry coupled with engineering intuition.

Based on the team’s previous research into funicular form finding, the design uses weak springs to automatically generate a zero bending moment surface, enveloping a large trade stand and allowing the public to circulate underneath. It uses a mesh of thin plywood plates joined via simple expressed hinged pin connections. The structure was modelled with the extensive use of generative 3D systems with the output linked to a CNC router.
