- Abstract
In order to study the seismic reduced performances(SRP)of series isolation systems (SIS) under multi-dimensional seismic excitation(MDSE), a series of shaking table tests had been conducted for the SIS model. The two groups of seismic waves, including the near fault ground motion and far fault ground motion were firstly chose from the Chichi earthquakes as the input. The responses of SIS under the different seismic waves were predicted by response spectrum method. The paper discussed the effect of earthquake intensity on SRP of SIS under different input patterns, and further analyzed the effect of near fault ground motion and far fault ground motion on the SRP, and compared to the predicted results. The results show that, compared to near fault ground motion, the seismic reduced ratio (SRR) of SIS is better under the far fault ground motion. The SRR of SIS increases with increasing the earthquake intensity, but it is obvious under near fault ground motion. The test results are consisted with the predicted results. The SRRs are small for the different shaking table tests, since the SRP of SIS is better. Moreover, the SRP under 2-dimensional seismic excitation is consistent with that under 3-dimensional seismic excitation with increasing the earthquake intensity.
