橋梁基礎の地震応答解析と耐震設計

Abstract

While a number of studies concerning to soil-structure interaction problems have beenperformed, the results of those studies are not necessarily reflected in the design of actualfoundation of structures. The reason is mainly due to the fact that the physical model fortheoretical analysis is different from that for the design purpose and they do not have the commoncontants describing the models.The procedures to introduce the mass and damping effect of surrounding soils to the designmodel is discussed in this report on the bases of the theoretical deduction and experimentalconfirmation of the complex stiffness for cylindrical caisson and sheet pile well foundation.Succedingly a physical model is presented, which has a modified mas and spring constantsreflecting the interaction between the soil and bridge foundations.
