This brochure shows principle, concept, analysis of SI for buildings.
Principle of Seismic Isolation for Buildings
The following animations show the properties of buildings during earthquakes.
Building vibration is severe, there are possibilities that furniture will move and overturn sometimes, doors distort, and walls crack.
Building vibration is very slow, there are few possibilities of the foresaid situations.
Simulation vehicle is installed seismic isolation system and generating system of earthquake ground motions. The video of the right side shows shaking situation of conventional building during the Kobe earthquake, the video of the left side shows shaking situation of seismically-isolated building during the same earthquake. The difference of shaking is significant, especially reduction of severe shaking is recognized in case of seismic isolation.
