Previous studies have suggested that rocking vibration accompanied with uplift motion might reduce the seismic damage of buildings subjected to strong earthquake motions. [...]

It has been pointed out that buildings during strong earthquakes have been subjected to foundation uplift. The rocking motion accompanied by uplift can reduce the damage [...]

Recently earthquake ground motions with large amplitude and/or long period component act on seismically isolated buildings. In case of family houses, responses of isolate [...]

Currently lots of buildings are required to be functional or recovered promptly even after sever earthquakes. To make them meet this requirement, we propose a self-center [...]
