ABSTRACT
This paper reports on the finite element analyses of two ancient groined masonry vaults. The computations were part of an extensive study aimed at the reconstruction and retrofitting of the vaults that cover the transept of the church of Our Ladies Monastery in the city of Magdeburg, Germany. Both linear elastic and nonlinear analyses were performed to clarify the influence of several load impacts on the structural behaviour, with the sideward slope of the abutments ultimately found to be most responsible for weakening the structure. Based on the calculated results, appropriate reconstruction methods were proposed.
