Performance of Isolated Buildings with Superelastic-Friction Base Isolators under High Seismic Hazards
The seismic performance of a three-story building isolated with superelastic-friction base isolator (S-FBI) systems is evaluated relative to ground motion intensity associated with a risk level of 2% probability of exceedance in 50 years. The S-FBI system consists of a flat steel-PTFE sliding bearing and superelastic shape memory alloy (SMA) elements. An analytical model of the isolated building with the S-FBI system is developed to determine the response of the structure subjected to a seismic event. Seismic response of the non-isolated building is also evaluated for comparison purposes. Nonlinear response history analyses are conducted under a suite of 22 ground motion records. Peak interstory drift ratio, peak isolator displacement and residual isolator displacement are selected as the primary response quantities. Performance objectives based on the story drift ratios are defined. The effects of mechanical properties of the S-FBI system on the performance of the isolated buildings are examined.
