Sažetak
Static and dynamic methods of nonlinear seismic analysis for reinforced concrete non-seismic buildings are presented in this paper. The ICONS experimental model was used on a reinforced concrete four-story frame with three bays, which was calibrated with a numerical nonlinear model. The chosen earthquake record was a moderate-strong scenario of the European Seismic Hazard. The numerical model showed excellent correlation with the experimental behavior of the ICONS model. The methods that were used in this study are as follows: pushover analysis, time history analysis, and incremental dynamic analysis. The advantages and disadvantages of each method are described, and the results obtained by their application are presented. The pushover analysis shows the expected global response of the structure, which is confirmed by the numerical results and recommendations for performance levels. The results obtained from the time history analysis are interstory drift profiles based on three different peak ground accelerations. Finally, the incremental dynamic analysis shows fragility curves based on the first natural period of the structure.
