In this thesis a numerical model for the efficient simulation of large scale masonry structures with the finite element method is developed. In experimental tests typical crack pattern with a preferred horizontal, vertical and diagonal orientation were observed. In the numerical calculations, these cracks are modeled with corresponding oriented interface elements (discrete crack model). These elements are arranged in a so-called unit cell. The step-wise failure through horizontal and verical mortar joints is described by a diagonal interface element. With this simplification, the high quality of discrete crack models at meso scale simulations can be combined with the numerical efficiency of macromodels.
