Poenostavljena ocena potresne zmogljivosti stavbe : diplomska naloga št.: 217/OG-MK = Simplified seismic performance assessment of the building : graduation thesis no.: 217/OG-MKZupančič, Žiga, gradbenikV diplomski nalogi je opisana in izvedena poenostavljena ocena potresne zmogljivosti stavbe Fakultete za gradbeništvo in geodezije Univerze v Ljubljani, zgrajene leta 1969. Geometrija stavbe in ... karakteristike vgrajenih materialov so prevzete iz prejšnje študije. Za oceno potresne zmogljivosti stavbe je uporabljena metoda N2, ki je del standarda Evrokod 8, vendar je potisna krivulja nadomeščena z poenostavljeno potisno krivuljo, ki je definirana z začetno togostjo, nosilnostjo in deformacijsko kapaciteto konstrukcije. Začetna togost je bila ocenjena z uporabo linearne analize tridimenzionalnega numeričnega modela konstrukcije. Nosilnost konstrukcije je bila določena po modelu minimalne nosilnosti, ki je vključen v japonski pravilnik za oceno potresne zmogljivosti stavb, deformacijska kapaciteta konstrukcije pa na podlagi nelinearnih pomikov kritičnih elementov v kritični etaži, ki so izračunani z enačbo v zaključeni obliki. Tako za vzdolžno kot prečno smer se za kritična elementa konstrukcije izkažeta veliki armiranobetonski jedri v prvem nadstropju. Ocenjena potresna zmogljivost je precej odvisna od nihajnega časa. Izražena z maksimalnim pospeškom tal pri mejnem stanju blizu porušitve stavbe znaša 0,40 g v vzdolžni in 0,23 g v prečni smeri. Tako določena potresna zmogljivost je nižja od potresne zmogljivost stavbe, ki je bila ocenjena v predhodni študiji na osnovi konvencionalne potisne analize, za 25,4 % v vzdolžni smeri in 8,0 % v prečni smeri. Manjšo razliko smo opazili za primer, ko nihajnega časa nismo dodatno zmanjšali zaradi vpliva idealizacije potisne krivulje.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
