This figure clearly represents the differences and key trends in seismic behavior characteristics previously identified in Figures 22 and 23. In the horizontal directions (X and Y), the discrepancies between experimental and numerical results across all three amplification ratio estimation methods and over the entire frequency range increased relatively linearly with rising seismic motion.
