ITKE contributes to the Thematic Pavilion at the Expo 2012 Yeosu, South-Korea

Recently, the ITKE was given the opportunity to contribute with their research on elastic deformations and bio-inspired mechanisms for another project of an architectural scale – The Thematic Pavilion at the EXPO 2012 in Yeosu, South Korea. The design of the pavilion was done by soma architecture, Vienna. The institute helped in the development of the Kinetic Facade as part of Knippers Helbig Advanced Engineering.

The Thematic Pavilion is one of the main buildings of 2012 Yeosu Expo. One of its main features is the 140m long and up to 13m high facade. 108 operable lamellas can be adjusted to requirments of light and building physics. Additionally, the kinematic facade allows to run special choreographies and act as a moveable eye catcher and media screen. Inspired by the institute’s research on plant movements and kinematic mechanisms like the Flectofin, the here implemented system, which was further developed by Knippers Helbig, is also based on elastic deformation and utilizes the failure mode of shell buckling to its favor to obtain a unique motion. Central to this structural concept is to use FRP lamellas with defined stiffness distribution. Actuators at top and bottom of each lamella are compressing the lamella asymmetrically which creates a deformation outwards and sidewards, which opens the facade.  Various LEDs illuminate the facade during night time and intensify the visual motion of the facade.
