WebApr 23, 2024 · Acceleration time history shows that the acceleration of the structure becomes smaller when SSI effect is considered. However, the peak frequency of the FRS is reduced from 4.642 Hz to 2.477 Hz due to soil flexibility. At this frequency, spectral acceleration of SSI model is much bigger than that of the fixed model.
