The model shows the use of the “Pneumatic Wedge Method” for doubly curved concrete surfaces that do not require complex formwork and scaffolding. As part of a research project at the Vienna University of Technology, the deformation and the final state of the concrete shell were simulated using RFEM. The maximum bending moments of 0.40 kNm/m under self-weight and 1.50 kN/m² under snow load were calculated. Further information can be found here. RFEM supports the analysis of such innovative construction methods. Model (© TU Vienna).
