| Abstract: | The more rational numerical model for the problem of 2 D frame structurefoundation dynamic interaction in frequency domain is presented by using a coupling model of beam element finite element infinite element.The effects of the structure with the foundation dynamic interaction bot on nature vibration characteristics and earthquake responses as well as parameter influences are analyzed and studied.The conclusions which are introduced are available for reference of engineering anti seismic design. |
