Secondary title:	ǂThe ǂeffects of the seismic action on the non-structural ele,emts of building
Secondary abstract:	The present work focuses on estimation of seismic influences on non-structural elements of buildings. For example, larger scale accidents could happen because of damaged installation or equipment in buildings of higher importance like nuclear power plants or chemical factories. In addition it is important that hospitals keep functionality after an earthquake and that the potential losses of expensive equipment are as small as possible. In the first part of the study the floor response spectra for the model of idealized structure is investigated with SAP2000 software. Time-history analysis from accelerograms of three nearby earthquakes is provided to get floor response spectra. The mean values of three recorded and three generated accelerograms are compared. Three-storey asymmetric reinforced concrete building SPEAR is analyzed afterwards. Observation of changing floor response spectrum with height and over one storey is made, where eccentricity of masses is major influence. In the last part of the thesis the seismic isolation system, which currently represents the alternative to seismic resistant construction is studied. Lead rubber bearings of different characteristics are modeled under SPEAR building in SAP2000. Nonlinear link element is used to describe the histeretic behaviour. Two types of nonlinear time-history analysis are computed, the direct integration and Fast nonlinear analysis (FNA). Floor response spectra for different isolation characteristics are compared. Those results are compared also with unisolated building SPEAR and with Eurocode 8 floor response spectra, which is calculated with simple formula.
