The paper presents analysis of limit state of bearing capacity and reliability of masonry structures. A masonry made of Autoclaved Aerated Concrete (AAC) with mortar for thin-layer joints was proposed. The basic calculations were carried out using the procedures available in the Eurocodes. A comprehensive analysis of the work of the masonry element was carried out. The numerical FEM model of the masonry member was made. A quantitative assessment of the safety of the structure was made by calculating the reliability index. During numerical simulation three parameter elastic-plastic model for material of masonry was used. All parameters were based on material experimental results. The analysis of masonry reliability was carried out using the probabilistic method. Masonry elements are widely used in construction, therefore their design should be based on a detailed analysis. Noteworthy is class execution of works of masonry structures and relatively high values of safety coefficient associated with it.
