Povzetek: In the paper, a part of the research performed at the University of Ljubljana, aimed at better understanding the elastic and inelastic seismic response of asymmetric structures, is summarised. The influence of the most important structural parameters are studied on idealised single-storey structures. A model with three elements in each of two orthogonal directions is used. The model is asymmetric with respect to both horizontal axes. No specific code requirements were taken into account. Rather, some limit cases of strength distribution are investigated. Analytical expressions are derived for the determination of elastic response of structures subjected to ground motions defined by response spectra. Elastic response spectrum analysis, as well as linear and nonlinear time-history analyses have been performed on a number of test structures. The response parameters studied are displacements. Comparisons are made between elastic and inelastic responses. The difference between the behaviour of torsionally stiff and torsionally flexible buildings is discussed. The difference between the behaviour of torsionally stiff and torsionally flexible buildings is discussed. The influence of the type of eccentricity is studied. Furthermore, the response of structures subjected to bi-directional and uni-directional horizontal excitation is compared. From the results of analyses several conclusions are drawn. They are based on a very limited number of test examples. Nevertheless, at least some of them seem to be generally valid. The most important may be the observation that fair estimates of the response to bi-directional ground motion can be obtainedby the SRSS combination of responses to two independent uni-directonal ground motions [COBISS.SI-ID 756833]
