To make reasonable policies of earthquake disaster reduction, it is necessary for local authorities, civilians and engineering professionals to have consensus recognitions of earthquake hazard. A vivid simulation of seismic damage of structures within a city, in both views of all buildings in the city and individual houses, is helpful in making the consensus. As advance of computer technologies and structural analysis methods, it is possible to conduct digital simulation and visualization of seismic response for a whole city. But a big problem remaining is how to model all the structures, mainly buildings, of a city. On utilizing 3D GIS data, this study provides a method of constructing structural models of huge amount of buildings of a city, which enables seismic analysis of building structures. An illustration is also give by constructing building models of Bunkyo-ku, Tokyo using available GIS data.
