Dynamic Analysis On Groundwork-High Structure System

Once the great important structure, such as high building, high dam undergo destroyed, the effect will be quite serious. In general dynamic engineer design, it is common to adopt rigidity groundwork model, to analyze the dynamic characteristic and dynamic respond. However, the structure and the groundwork are an organic whole. If detached them artificially, perhaps bring a distortion result of earthquake response. So, it has great meaning in project to research the dynamic interaction on high structure-groundwork system.This thesis based on theories of finite and infinite element to establish the model of high structure-groundwork system, and research the influence of interaction to dynamic property and earthquake response of structure.The author chosed rigid groundwork model and elastic groundwork model for comparing and analysis. Furthermore accomplished a program to calculate dynamic characteristic of large-scale plane structure, which is developed in FORTRAN. As to the both models, ANSYS is used to analyze their dynamic property and earthquake response. Moreover, with regard to the elastic finite-infinite element coupling model, the author uses mapping infinite element...
