Sekundarni naslov: Comparison of different non-linear methods for seismic resistance of masonry structures
Sekundarni povzetek: In the thesis different methods for non-linear static analysis are used to calculate seismic response of a masonry building, and results compared to a shaking table test of a masonry structure, which was performed at the Slovenian National Building and Civil Engineering Institute. The focus of the thesis rests on the use of different computer programs for seismic analysis, which are based on different methods, use of simple methods of calculation and comparison of the obtained numerical results with the measured and observed response of a shaking table test. In the first part of the thesis an overview of basic concepts regarding seismic resistance and response of masonry structures is presented. Different failure modes of unreinforced masonry are presented and the story failure mechanism is described. Different methods for modeling are presented and explained, including a procedure based on micro-modeling and two methods based on finite elements and the equivalent frame method. The method based on the story mechanism is also presented. In the part of the thesis which deals with numerical calculations, the analyzed structure and the results of the shaking table tests are presented. Next, non-linear seismic analyses are performed with computer programs AmQuake and Sremb3D and with the story mechanism method. In addition to calculations, the theoretical background of the methods, the modeling procedure and the calculation of the seismic response are also explained. Finally, the comparison of all three analyses and the shaking table test results is presented. The pros and cons of different methods, including comments on their usability, accuracy and complexity are presented in the end.

Povzetek (ePrints): V okviru diplomske naloge so uporabljene različne metode nelinearne statične analize za zidane konstrukcije in rezultati primerjani s preiskavo izvedeno na potresni mizi na Zavodu za gradbeništvo Slovenije. Poudarek je na primerjavi rezultatov različnih računalniških programov za račun potresne odpornosti zidanih konstrukcij in bolj enostavnih metod ter koliko se ti rezultati približajo eksperimentalno izmerjenim rezultatom. V prvem delu naloge je opravljen pregled osnovnih pojmov potresne odpornosti in odziva zidanih stavb. Predstavljen je račun odpornosti za tri bistvene tipe porušitve nearmiranega zidovja. Opisani so etažni porušni mehanizmi. Razloženi so načini modeliranja zidovja in predstavljen je postopek mikromodeliranja, ter dva načina modeliranja s končnimi elementi po metodi z nadomestnimi okviri. Opisana je metoda etažnega mehanizma, ki nam da rezultat v obliki etažne histerezne ovojnice. V računskem delu je predstavljena obravnavana konstrukcija in rezultati preiskav na potresni mizi. Nelinearna seizmična analiza konstrukcije je bila opravljena s programskima paketoma AmQuake in Sremb3D ter z metodo etažnega mehanizma. Poleg izračunov je v tem delu razloženo tudi teoretično ozadje programov, postopek modeliranja zidane konstrukcije in račun potresnega odziva konstrukcije. Opravljena je primerjava rezultatov vseh treh analiz z rezultati preiskave na potresni mizi. Predstavljene so prednosti in slabosti posameznih metod, njihova uporabnost, natančnost in zahtevnost.
