This study also explored the appropriateness of the simplified SSI system to simulate the real SSI system. The results showed that the horizontal displacement transfer function of both systems are well consistent and the error on the main peak is only 2% or less. While the error on the maximum acceleration of both systems is also less than 2% under the horizontal earthquakes. Therefore, the simplified model seems to be applicable to the dynamic analysis of MRF building structures systems. This study also discussed the influence of beam-to-column stiffness ratios on the dynamic response for SSI system. The results showed that the main peaks on the transfer function may be underestimated by more than 17% when the upper structure is simulated as a shear building without considering beam-to-column stiffness ratios. Therefore, it is more reasonable to simulate the upper structure of the building using a MRF rather than the shear building. In addition, under the horizontal erathquake, the beam-to-column stiffness ratios can affect the deviation on the maximum acceleration of SSI system up to about 7 times. Thus, the beam-to-column stiffness ratios should be an important design parameter in seismic design. Shi-Shuenn Chen 陳希舜 2018 學位論文 ; thesis 105 zh-TW
