| Research Abstract |
The main results of this study may be summarized as follows :
1. A means of establishing preventive measures was presented for mitigating earthquake damage by making the most of a variety of information and such advanced technoligies as computer technologies on-line in real time, using studies and systems now in operation. This study focused on the concept and importance of real-time earthquake engineering. Active control of social systems taking into account human behavior also was dealt with.
2. A seismic information gathering and network alert (SIGNAL) system for a large-scale city gas network was developed based on extensive earthquake monitoring and geophraphic information system (GIS). The damage estimation to custimers' buildings and pipelines, estimation of the magnitude and hypocenter, evaluation of the response spectrum, and decision analysis whether to shut-off or maintain the supply based on the estimated results were conducted.
3. A new simulator for human evacuation behavior using virtual reality (VR) was developed and applied to study evacuation from a maze. It was found that evacuation behavior can be simulated by the VR system, and the trainig using VR helps smooth evacuation from the maze. Considering the issues related to disaster drill, such as its mannerism, decrease of participants and their low volition, and safety of the drill, this VR simulator has high potential and can be a useful tool for disaster mitigation.
4. Importance or criticality in relation to a road network was evaluated in terms of the importance of the route the bridge located in the road network as well as the direct effects when the bridge is destroyed. Priority for retrofitting bridges and for emergency response after an earthquake occurrence can be decided accoring to the importance factor of the bridge as a vital transportation link.
