Abstract
The paper presents an integration of a Geographic Information System (GIS) and Multiple Degree of Freedom (MDOF) model for structural dynamic calculations. The input data of MDOF is stored in the format of spatial data model in GIS with 2D and 3D with the help of Google SketchUp. The output data of MDOF can be viewed in both 2D graph and 3D visualization after simulation calculation in GIS. A case study of dynamic response of campus buildings is presented to illustrate how the GIS-coupled system has been developed. Results show that the proposed GIS-model integrated system can perform a large number of dynamic responses of MDOF affected by earthquakes, promote better earthquake resistant behavior of building structure in urban regions, and thus optimize hazard assessment, vulnerability estimation and seismic risk reduction.
