| Outline of Final Research Achievements |
By shaking table tests using two types of building models with three different soil conditions, it was clarified that (1) higher mode vibrations during uplift excursions are not seen much in a soft ground while those vibrations appear remarkably in a rigid ground, and (2) the damage of the superstructure is suppressed in a soft ground and the residual deformation is relatively small.
And by earthquake response analysis using a computer program created by us, amounts and distributions of seismic forces and so on were grasped.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の成果は簡易かつ安価に地震応答低減効果を獲得するための建築構造の選択肢を拡充することに貢献するため、建築構造設計の自由度の拡大や減災の観点で社会的意義を有すると考える。
