Abstract
Diplomska naloga obsega analizo potresne odpornosti novo zgrajene enodružinske zidane hiše na Dolenjskem. Pri analizi smo upoštevali zahteve standardov Evrokoda 6 in Evrokoda 8. Analizirali smo le spodnjo etažo objekta. Potresno analizo smo izvedli po metodi s horizontalnimi silami. Nosilnosti posameznih zidnih elementov smo določili na osnovi upogibnega mehanizma porušitve, strižnega mehanizma z upoštevanjem zdrsa ter strižnega mehanizma s pojavom diagonalnih razpok, ki ni predviden v omenjenih standardih. Vpliv armiranobetonskih vezi na nosilnost sten smo v računu zanemarili. Za določitev potresnih sil, ki delujejo na posamezni element objekta, smo uporabili programsko orodje SAP2000, v katerem smo hišo modelirali. Naredili smo ploskovni in linijski model in ugotovili, da se dobljene vrednosti potresnih sil v posameznem elementu med seboj dobro ujemajo. Pri oceni potresne odpornosti smo izvedli dve različici, kjer smo nosilnost sten računali z in brez upoštevanja strižnega porušnega mehanizma z zdrsom, saj je takšen mehanizem poškodovanosti le redko zaznati v spodnji etaži zidanih objektov. Če smo pri računu nosilnosti upoštevali strižni porušni mehanizem z zdrsom, se izkaže, da potresna odpornost objekta ni dosežena v prečni kot tudi ne v vzdolžni smeri. V nasprotnem primeru pa se izkaže, da je obravnavana stavba potresno odporna. Glede na to, da standard zahteva račun nosilnosti na osnovi strižnega mehanizma z zdrsom, moramo zaključiti, da potresna odpornost objekta ni zadostna.

Title:Evaluation of seismic resistance of masonry building in the area of Novo mesto
Abstract:
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.
