Outline of Final Research Achievements

In order to reuse existing piles that would become the problem in the near future, new building foundation method was proposed by representatives of this study. Seismic observation of the new building foundation model of actual-size was conducted to investigate the seismic behavior of the structure with the new foundation. The peak response accelerations of structure with the new foundation are lower than those with the other foundations. The mechanism of the seismic response of structure with the new foundation was demonstrated by computer simulations of the dimensional finite element model.
