Reconstruction of the Frauenkirche Dresden: Structural proof-checking using a complete 3D FE-model

The application of the Finite Element Method for the analysis of complex masonry structures is illustrated using the reconstruction of the Frauenkirche in Dresden as an example. In context with the proofing procedure this analysis method is applied to establish completely independent comparision calculations. In a model of half of the church all major structural components such as cupola, wall- and tower-buttresses, pillars and choir, are included. This complete model allows the checking of the load path and the complicated geometry as well as several parametric studies. The effects of different structural and foundation stiffness ratios can also be investigated. This contribution shows that the chosen calculation method using a complete three-dimensional system, which initially seems to be an unusual approach in relation to a masonry building is, however, a substantial tool for such comparison calculations. These completely independent comparison calculations necessitate a considerable amount of work which is nevertheless appropriate regarding such a significant building.
