Development of Integrated Earthquake Simulation for Estimation of Strong Ground Motion, Structural Responses and Human Actions in Urban Areas

numerical simulation, the authors have been simulating the whole phases of anearthquake, i.e., the generation and propagation of an earthquake, the response and damage of structures, and the human and society actions against the earthquake damages. This is the integrated earthquake simulation (IES). With the aid of the latest geographical information system (GIS), IES is able to automatically construct a compute model for a city of some hundred meter scale. This paper presents the development of IES, focusing the simulation of strong ground motion and structure responses; the structure response simulation is made by several numerical analysis methods and the data exchange between each method and IES is controlled by an interpreter program. Discussions are made on the usefulness of IES. It is pointed out that IES provides vital information to form common recognition of possible earthquake hazards and disasters among government officials and residents.
