Design and performance study of a segmented intelligent isolation bearing

In this paper, a novel type of isolator, named segmented intelligent isolation bearing (SIIB), is designed and manufactured, which can meet the requirements of seismic fortification under three seismic intensities, i.e. frequent intensity, basic intensity, and rare intensity. A theoretical formula f...
