The thesis deals with the analysis of seismic resistance of a new, single family masonry house in the Dolenjska region. We analysed only the lower storey of the building, considering all necessary standard requirements of the Eurocode 6 and Eurocode 8. The seismic analysis was done by the method of horizontal forces. The strength capacities of individual masonry wall elements were determined on the basis of flexural mechanism of the collaps, the sliding shear mechanism and the shear mechanism characterized with the formation of diagonal cracks, what is not determined in the above mentioned standards. The calculation neglects the impact of reinforced concrete on the capacity of walls. The program SAP2000 was used to model the house as well as to determine the seismic forces on individual building elements. According to the shell and line models we made, we found the values of seismic forces fit quite well. To evaluate the seismic resistance we took two versions where the wall capacities were calculated with and without considering the sliding shear mechanism, since such failure mechanisms can rarely be observed in lower storeys. However, our calculation following the sliding shear collapse mechanism, proves that seismic resistance in horizontal and vertical directions was not obtained. On the other hand, without considering this method, the building seems to be seismic resistant. Although the standard requires the calculation of capacity, based on the method of the sliding shear mechanism, we can conclude that the seismic resistance of the building is not sufficient.
