Retractable Membrane Roof Buchs, CH / Wandelbares Membrandach Buchs

more info: The foldable Membrane roof spans over a 50m long pedestrian road in the center of Buchs, Switzerland. In the deployed state the membrane takes on an undulating shape, pronounced by sharp ridges and valleys. The retracted membrane is collected under a parking bridge at the northern end and presents itself as the entrance arch of the road. During deployment of the roof it is pre-stressed in both directions to generate its final wind stable state. Wind tunnel tests
