下部構造の弾塑性特性の上部構造地震レスポンスヘの影響

Abstract

The effect of foundation compliance on the earthquake response of a multistory buildingwas interested. Both the structure and the foundation were assumed to have non-linear, hys-teretic restoring force characteristics with the yield points being varied in some probablerange. The earthquake responses of the building due to idealized ground motions were an-alyzed by using an electronic analog computer. Comparison was made between the maximumstory distorsions of the building for the different types and values of foundation compliance, and it has been concluded that the relative rigidity of the structure to the substructuremust have an optimum value that will minimize every story distorsions of the building foran intensive earthquake.
