Numerical arch and vault analysis

The present contribution discusses various approaches towards the numerical analysis of arches, particularly finite element methods based on a continuum mechanics approach vs. rigid-body approaches. We employ beam elements and a simple model for the interaction between axial compression and bending. The model is based on the assumption that cracks follow the radial joints, and on a simplified concept of incorporating finite compressive strength. We establish a transition.
