Case	Time history amplitude (mm)			Fourier peak frequency (Hz)
	1 Hz sine wave	2.8105	2.2821	0.8120	1.001	1.001	1.000
3 Hz sine wave	39.6298	36.6342	0.9244	3.0032	3.0029	0.999
Taft record	5.98947	5.1189	0.8547	3.418	3.412	0.998

and are the amplitude of experimental and numerical results for relative displacement time history curves, respectively. and are the frequency corresponding to the peak point of Fourier spectrum curve in experimental and numerical results, respectively.
