Abstract

The 2011 off the Pacific coast of Tohoku Earthquake caused extensive damage to many buildings by the tsunami, but no structural damage to seismically isolated buildings (SIBs) has been reported, and the safety of SIBs against tsunami is still unclear. In this study, hydraulic model experiments were conducted on SIBs to analyze the surge forces acting on SIBs and the pressure distribution on the superstructure. In addition, the response of the seismic isolation interface was analyzed to study the dynamic effects of the surge forces on SIBs.
