One concern in the design of base isolated structures is the selection of isolation system properties so that optimal performance is achieved over a range of seismic levels and performance metrics. To withstand very rare ground motions, isolation bearings are frequently designed with significant strength or damping, and as a result such devices provide reduced isolation effect for more frequent seismic events. These frequent events may contribute significantly to expected life-cycle earthquake losses, and should be considered in the framework of seismic hazard mitigation.

One concern in the design of base isolated structures is the selection of isolation system properties so that optimal performance is achieved over a range of seismic levels and performance metrics. To withstand very rare ground motions, isolation bearings are frequently designed with significant strength or damping, and as a result such devices provide reduced isolation effect for more frequent seismic events. These frequent events may contribute significantly to expected life-cycle earthquake losses, and should be considered in the framework of seismic hazard mitigation.

To investigate possible improvements to the design of isolated structures, an extensive research program was conducted. Analytical and experimental investigations are presented to characterize multi-stage spherical sliding isolation bearings capable of progressively exhibiting different hysteretic properties at different stages of response. This newly developed triple pendulum isolator incorporates four concave surfaces and three independent pendulum mechanisms. This thesis summarizes shaking table test results on a 1/4-scale seismic isolated steel braced frame on multi-stage hearings. Harmonic characterizations tests and earthquake simulations were conducted considering various levels of response, multi-component excitation, bearing uplift, and superstructure response. These experimental results are used to validate an analytical model.

$a
The newly developed analytical model is implemented as part of a parametric study of single- and multi-story buildings incorporating a wide class of isolation systems. Behavior of the new triple pendulum bearing is compared with that of linear isolation systems with both nonlinear viscous and bilinear hysteretic energy dissipation mechanisms. From both incremental dynamic analysis and an ensemble of response history analyses, important response parameters for the isolation system and superstructure are reported for all cased considered.

The results of parametric analyses are used to develop a design framework based on targeting a multi-objective Seismic Performance Classification (SPC). This SPC is introduced to describe satisfaction of a complex seismic performance objective, defined as aggregate damage state limitation over multiple levels of seismic hazard. The probability of satisfying specific SPCs is computed for three- and nine-story buildings on all classes of isolators investigated.

The experimental results confirm the numerical model developed for the new triple pendulum bearing. The results of the parametric analyses and probabilistic studies demonstrate the importance of limiting both interstory drift and floor acceleration to satisfy enhanced SPCs, and the sensitivity of these responses on the level and type of energy dissipation present. The new triple pendulum bearing, along with certain classes of viscous and hysteretic devices, are found to exhibit favorable characteristics toward achieving complex seismic performance objectives.
