 abstract={The article presents numerical analysis of a typical residential building in the Upper Silesian Coal Basin, which was erected in the early twentieth century and was not protected against mining ground deformations. The greatest impact of ground deformation on buildings are ground horizontal strain ε and ground curvature K. Numerical calculations included the building and the ground to take into account the effect of soilstructure interaction. The structure of the analysed building was made of masonry with wooden ceiling and roof elements. The ground was implemented as a layer 3.0m below the foundations and 3.0 m outside the building's projection. Construction loads are divided into two stages – permanent and functional loads as well as ground mining deformation. The maximum convex curvature K+ and the horizontal strain of the substrate ε+ were achieved in the 8th load step. The results of the analyses were presented in the form of stress and deformation maps. The most important results are the magnitude of the main tensile stresses σmax, which could to create cracks in the structure may occur after exceeding the tensile strength ft of the material. The presented method can be used to the analysis of endangered building objects by mining ground deformations.},
