A roof made of steel and fabric membranes was designed for the soccer stadium in San Bernardo, a city in the south of Santiago. The elegant, curved design in lightweight construction now also covers the standing area.
Wildlife crossing AM2 was built with a construction method for concrete shell structures called Pneumatic Forming of Hardened Concrete (PFHC). This new method was developed by TU Wien in the context of the research project titled "Double Curved Shell Structures."
The "Pneumatic Wedge Method" is a new method for the construction of double-curved concrete surfaces using pneumatic formwork. The advantage of this method is that elaborate structures for molds and scaffolding are no longer needed.
Using the "Pneumatic Wedge Method", the Vienna University of Technology has built a double-curved concrete shell as part of a research project. The deformation process and the final structural conditions have been checked with RFEM.
