Seismic performances of the structures at variation of artificial accelerograms

Abstract

The impact of changes to artificial-accelerogram parameters on the seismic performance of structures is examined in this paper. The seismic response and seismic damage are analysed in this respect. Nonlinear response of the system is determined by the incremental dynamic analysis (IDA), while the damage analysis of the system is considered using the damage index. The study has shown that generation of artificial accelerograms requires a considerable number of cycles, which improves the correspondence between the range of recorded response spectra and the range of the response spectra according to EN 1998-1, which is measured based on deviation of spectral acceleration curves as a function of the ductility of the system.
