In Figure 4 the structural responses of the fixed-base (fix) model and of the DSB base-isolated model (DSB) under El Centro seismic wave are compared in terms of (a) normalized peak story accelerations for different PGA values, (b) maximum story displacements.
Figure 4 Summaries of Normalized Peak Story Acceleration and Maximum Story Displacement under El Centro Earthquake Wave The comparison of the time history of roof acceleration response between the fixed-base and DSB base-isolated structures under the El Centro earthquake of 0.4g in PGA is shown in Figure 5.
Figure 5 Roof acceleration of fixed-base (fix) and DSB base-isolated (DSB) steel structure during El Centro earthquake (z direction, PGA=0.4g) Figure 6 Isolation effect under four sets of earthquake waves Conclusions Vertical base isolation has been applied to enhance the seismic performances of three-story steel frame model.

Meng-Hao Tsai, et al [6] conducted a shaking table test of a scaled bridge model to verify the effectiveness of the rolling-type bearing as a seismic isolation device.
The chosen recorded waves are El-centro and Chichi waves which meet the requirements for nonlinear time history seismic analysis under II site condition while the chosen artificial wave is transformed from the response spectrum in the code.
Subsequently the seismic performance of piers and bearings are compared between case1 and case2. 3.1 Seismic performance of piers Simulation results show that the seismic response of the bridge is the largest under El-Centro earthquake input; therefore, Fig.7 shows the moment and the rotation angle of piers under longitudinal and transversal El-centro excitations for both case1 and case 2.
The maximum value appears in the sliding bearing upon abutment A-2 under El-centro excitation with a value of 124.7mm therefore the suggested longitudinal designed displacement for the sliding HDR bearings is ±150mm.

Results showed that the rocking wall can make the original structure deformation uniform, which can effectively control deformation concentration[[3] Haiyun CAO, Peng PAN, Lieping YE, et al. 2011.
Tianjin waves (E-W), EL-Centro and Taft waves are chosen, without changing the frequency spectrum characteristics of the three earthquake wave, but the peak accelerations all set as 2.2m/s2.

According to Mansour, El-Sabbagh and Yehia, SBR is incompatible with NBR [6].
Gibala et al. [11] also observed a decrement in ts2 for SBR compounds with the incorporation of powder rubber vulcanizate, which was ascribed to the migration of accelerator from the ground vulcanizate to the matrix.

Based on numerical calculation, it is clear that the Wolong wave is more likely to provoke second order vibration of high-rise structures than El Centro wave and Taft wave.
