(2018): Practical Application of an innovative concrete shell construction method: Construction of the deer pass AM2 by use of PFHC
BETON- STAHLBETONBAU. 2018; 113(3): 222-232.

Concrete shells are aesthetic and economic supporting structures, if properly designed. They can absorb high loads and can span large areas with little material. Unfortunately, high costs for the complicated formwork avoid a wider use in practice. A new shell construction method called Pneumatic Forming of Hardened concrete (PFHC) was developed at the Institute for Structural Engineering at TU Wien. Within a tight development process numerous material tests, tensile tests, bending tests and two large scale experiments were performed. Now, the Austrian railways (OBB) used the construction method to build the deer pass AM2 as concrete shell bridge over the two- rail track Koralmbahn in Carinthia in Austria. At first a test shell, which now serves as event canopy, was built with the plan dimensions 26.5 x 19.1 m and a height of 4.2 m. Directly after that the main supporting structure, the shell bridge, was built (plan dimensions 36.2 x 38.7 m, height 8.1 m). The first part of the paper which was published in the previous issue summarizes the development process of the new building method. Furthermore, the paper describes the building process of the two shell structures and chosen experiments for the construction process. Finally, the monitoring concept is explained.
