Foundation-Structure Dynamic Interaction During Earthquake

In recent years, there have been a certain number of experiments and numerical researches about the problem of dynamic foundation-structure interaction. But few works have been done on the visible analysis about this issue.Based on the research results of forth a goer, the interaction of soil-pile-structure on the condition of earthquake has been investigated. Reasonable FEM model has been made to simulate the dynamic interaction of foundation-structure system during earthquake;Visual C++ was used to program for the visibility of the process of the dynamic interaction.In the chapter 4, with this program, anti-earthquake analysis was taken on a 12-floors frame building as the system of foundation-structure interaction, and the result data was compared with the results from PKPM analysis.At last, with the same model and the same conditions, the relationship between pile depth, pile diameter and the anti-earthquake ability of the structure was studied, some conclusions were made.
