群杭フレームモデルによる杭基礎の静的解析プログラムの開発と計算例

抄録

We have developed a static analysis program for pile foundation by “pile group frame model”. “Recommendations for Design of Building Foundations” (AIJ) was revised, and pile foundation is now required to be designed for loads during large earthquakes with this model. This paper describes the analysis theory and calculation example of the program. These show the basic characteristics of this model and show that this model can evaluate the collapse mechanism of pile group. These are the basic knowledge for the rational “Limit States Design” of pile foundations.
