RFEM graphic with representation of maximum moments of 0.40 kNm/m in shell (final state) stressed by self-weight and snow of 1.50 kN/m2 (Screenshot: Dlubal) Shell after completion Concrete Shell Fabricated with “Pneumatic Wedge Method” at Vienna UT, Austria The “Pneumatic Wedge Method” is a new technique for the construction of double-curved concrete surfaces by means of pneumatic formwork. The advantage of this method is that complex structures for molds and scaffolding are not needed anymore. 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. Pneumatic Wedge Method The fabrication of the multi
