Sekundarni naslov:	Seismic performance assessment of masonry building in Posočje
Sekundarni povzetek:	The thesis addresses seismic performance assessment of a masonry building. Firstly, seismic behaviour of masonry buildings is briefly introduced. Described are typical failure mechanisms followed by a chapter presenting the design seismic load according to Eurocode 8 (EC8) and the determination of the resistance of the unreinforced masonry walls based on different failure mechanisms. An earthquake of magnitude 4.9 struck the Upper Soča Valley in 2004. During the earthquake, masonry building under investigation was also damaged. Data for seismic performance assessment of the masonry building (Chapter 5) were obtained based on the technical documentation provided by National Technical Office (DTP). The resistance of the walls was based on the theoretical background presented in Chapter 3 and Chapter 4. The calculations were made on the basis of horizontal force method using Microsoft Excel and SAP2000. The seismic performance assessment analysis was performed for the ground floor only. The results of the first verification of the resistance showed that the building is not capable to meet the requirements of the EC8 since the shear slip mechanism controlled the resistance of the ground floor. Based on the empirical evidence such failure mechanism is not likely to occur at the ground floor. Therefore it was not considered in the second iteration of the verification of resistance, which showed the increased resistance of the investigated masonry building for 88% and 103%, respectively, in X and Y direction. Still, such increased resistance, which was estimated in the second iteration, not fulfil requirement of EC 8.

Povzetek (ePrints):	Diplomska naloga obsega oceno potresne odpornosti zidane stavbe. Na začetku je predstavljeno obnašanje zidanih objektov na potresno obtežbo. Opisani so značilni porušni mehanizmi zidov. Sledita poglavja, kjer smo opisali določitev potresne obtežbe po standardu Evrokod 8 (EC8) ter mehanskih karakteristik zidov pri čemer smo se mejili le na nepovezano zidovje. Leta 2004 je območje Posočja prizadel potres z magnitudo 4,9. Potres je poškodoval tudi objekt, ki obravnavamo v diplomski nalogi. Na podlagi tehnične dokumentacije Državne tehnične pisarne (DTP) so bili pripravljeni potrebni podatki za izračun nosilnosti zidov ter potresne odpornosti celotne konstrukcije (poglavje 5). Pri izračunih uporabljene definicije in predpostavke so opisane v poglavjih 3 in 4. Izračuni so narejeni po metodi z vodoravnimi silami s pomočjo programov Microsoft Excel in SAP2000. Analiza potresne odpornosti smo izvedli samo za za pritlično etažo. Rezultat prvega preverjanja odpornosti pokaže, da objekt ne ustreza zahtevam standarda EC8. Pri vseh zidovih je vedno kritičen porušni mehanizem zdrsa, ki pa je v pritlični etaži glede na veliko vertikalno obtežbo malo verjeten. Zato mehanizma porušitve zaradi zdrsa nismo upoštevali pri drugem preverjanju potresne odpornosti. S tem se potresna odpornost celotne konstrukcije v smeri X poveča kar za 88 %, v Y smeri pa je povečanje 103%, vendar objekt kljub temu ne izpolni zahtevanih pogojev po EC8.
