| Abstract: | In this paper,the foundation is divided into finite layers in vertical direction. The spline finite element and the semi analytical infinite element are used to investigate the infinite soil. The decay and the phase difference of the earthquake wave are considered when building foundation building interaction system is investigated. Some conclusions on the earthquake responses of building foundation building interaction system are obtained. |
