Ultimate Behavior Analysis of Seismically-Isolated Structures
To prepare for a mega earthquake
Our laboratory is developing advanced analysis techniques for seismic isolation systems, and can predict the ultimate behavior of seismically-isolated buildings in the event of a mega earthquake, and propose various countermeasures to prepare for a mega earthquake.
Research
In a seismically-isolated building, the seismic isolators deform softly during an earthquake, greatly reduce response acceleration in the superstructure and improve the seismic safety. On the other hand, ultimate events such as collisions with retaining walls and buckling or rupture of the seismic isolation bearings may occur for the ground motions exceeding design level caused by a mega earthquake such as the Nankai Trough Mega Earthquake. By using analysis technologies to precisely predict the ultimate behavior of seismically-isolated buildings, it is possible to foresee the occurrence of ultimate events and to consider countermeasures to suppress their occurrence.
