Non-structural components (NSCs) should be analysed properly using the floor response spectra (FRS) method to reduce financial loss due to earthquakes. There are various methods available in the literature to scale recordings. However, there is little or no agreement among researchers regarding the correctness of these methods in the analysis of NSCs. Therefore, the present study examines the influence of different amplitude scaling techniques (geometric mean and Sa(T1)) and spectral matching procedures on the seismic demands of NSCs. The spectral matching method shows the lowest ground motion parameter dispersion. The results reveal that the Sa(T1) scaling method produces lower floor responses. The spectral matching method shows smaller dispersion in the spectral ordinates and median response quantities. The amplification factors estimated in this study were compared to those from the existing code formulations. Based on the findings of this study, the spectral matching approach in the time domain may be utilized to better estimate seismic demands on NSCsKeywords
