多自由度表示による地盤-構造物基礎系の振動解析について

Abstract

To analize the vibrational characteristics of the structure surrounded by surface layer, theauthors have proposed a new model with multi-degree-of-freedom. The proposed model is basedon the assumption that the surface layer be represented by lumped-masses system connected witheach other by springs and dashpots horizontally and vertically. Appropriateness of this modelhas been confirmed by comparison with the solution for a continuous system, and has been ap-plied to the analysis of the foundation-structure system, in which discussions were made on thebasis of some numerical results.
