The German "Digital Timber Construction" (DTC) Lab headed by Prof. Dr. Christopher Robeller has recently completed an impressive showcase of its research activities. It is a lightweight and environmentally friendly timber gridshell, which is part of the "Timber Structure Interface" (TSI) research project, built in Moritzplatz in the city of Augsburg, Germany.
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.
The self-supporting member shell structure consists of vertical glued-laminated girders, horizontal steel tubes, and diagonal steel cables.
