Abstract

Diplomska naloga obravnava postopek modalne analize. Najprej opiše pojav lastnega nedušenega nihanja nato pa uvede pojma glavnih koordinat in ortogonalnosti lastnih nihajnih oblik, ki sta poglavitnega pomena v tem postopku. Prikaže različne načine definiranja obtežbe: vsiljeno časovno spremenljivo obtežbo, potresno obtežbo, definirano s pospeški tal ter potresno obtežbo, definirano s spektrom odziva. Nato prikaže načine za določanje statičnih količin in načine za kombiniranje le-teh. V naslednjem poglavju je izdelan numerični primer obravnave enoetažne konstrukcije s tremi prostostnimi stopnjami po postopku modalne analize s spektrom pospeškov. Rezultati so preverjeni v programskem orodju SAP2000. V zadnjem poglavju je računalniško analizirana osemetažna stenasta AB konstrukcija – rezultat so nihajni časi in notranje statične količine v najbolj obremenjenem elementu.

Secondary title:	Seismic analysis of a multi-storey building
Secondary abstract:	Modal analysis is the main topic of the thesis. First, the phenomenon of undamped oscillation is defined and concepts of modal coordinates and orthogonality of mode shapes which are crucial to the process of modal analysis are introduced. Various methods of applying load are presented: forced time-variable load, seismic load defined by ground accelerations and seismic load defined by response spectra. Methods for determining internal forces and displacements are shown along with ways of combining them. Next chapter contains a numerical example of a simple one-storey structure with three degrees of freedom analyzed with the method of modal analysis (using an acceleration response spectrum). Results are then verified in SAP2000. In the last chapter an eight-storey reinforced concrete building is analyzed with SAP2000. Vibration periods and internal forces in the element resisting the largest load are presented.
