Resum
The recently proposed Roll-in-Cage (RNC) isolator, with an inherent self-stopping mechanism, is used herein for protection against near-fault earthquakes and to accommodate the expected large isolator displacement without using larger isolators nor bigger seismic gaps. The buffer mechanism is designed to draw any possible seismic pounding of a RNC-isolated superstructure downward to take place only within the RNC isolator’s bounds. The study investigates how to alleviate possibly arising unwan...
