Performance of Base-Isolated Building Frame for Extreme Earthquakes
Abstract Seismic design codes all over the world specify the concept of two-level earthquakes, one extreme earthquake (maximum credible earthquake) and other is design-level earthquake. Base-isolated buildings designed for design-level earthquake should be checked for their performances in the extreme-level earthquake. While under design-level earthquake, the framed structure remains in the elastic range but sufficient inelastic excursion may take place in the isolated frame in the extreme earthquake. The present study deals with the inelastic behavior of base-isolated frame subjected to an extreme level far-field and near-field earthquakes. Inelastic behavior of the structure is studied for different response parameters like base shear, top story displacement, isolator displacement, the formation of plastic hinges. A numerical study elucidates that for extreme level, the building goes highly into inelastic state in near-field earthquakes as compared to far field earthquakes.
