The analysed villa block building, that was randomly chosen is located on Beljaška ulica in Ljubljana. It is made from reinforced concrete elements. Its dimensions are used as the base of the initial model of the masonry building. All other models that were used in this parametric study were derived from this building. They diverge in dependence from the assigned parameters. The parameters in the analysis that were varies are number of storeys, the type of masonry structure, the compressive strength of masonry mortar, the characteristic friction coefficient and the material partial safety factor. Load cases that were considered were dead load, imposed load, snow load and seismic load. The load-bearing capacity of each individual wall is checked in respect to its geometrical data, mechanical properties and the associated load. Based on the sufficient load-bearing capacity of all walls for a given model, the global load-bearing capacity of the entire structure in elastic state can be estimated. The performed controls for the assessment of load-bearing capacity of the walls are within the linear elastic theory summarized from the Eurocode standard. With the new proposition of the next generation of Eurocodes come additional new controls, which are in this analysis compared with the already existing ones. The findings brought to us by this parametric study are summarized in the conclusion of the diploma thesis.
