This study explored the seismic
response of a house supporting base sides with a polymeric displacement control
material and by magnetically levitating the foundation base. In this paper, we
explore the possibility and efficacy of a seismic-isolated detached house as
described above from both a shaking table experiment of model and three-dimensional finite element analysis. The seismic-isolated
model showed stable response and its acceleration response was significantly reduced compared to the base-fixed model in
the shaking table test. Three-dimensional finite element analysis was
possible to simulate the experimental
results. In the seismic response analysis of afull-scale detached house, the seismic-isolated model showed response
reduction and its residual displacement was smaller than that of the
sliding-base isolation model.
