A DYNAMIC RESPONSE ANALYTICAL METHOD OF SOIL-PILE SYSTEM USING DYNAMIC INTERACTION SPRING

Abstract

The study investigates the validity of the proposed model for a dynamic response analysis of soil-pile system from numerical results of thin layered element method and Penzien model. Furthermore the numerical results of the proposed model was compared with earthquake observation results of pile group foundation. Numerical results of the proposed model considering frequency dependency and radiation damping of dynamic interaction spring agree with analyses by the other analytical methods and results of earthquake observation. The validity of the lumped mass model is verified through earthquake response analyses.
