| Research Abstract |
In the 1995 Kobe Earthquake, over 110 thousand houses were destroyed and more than 6,400 people died. Most of the people were killed by the collapse of existing low earthquake-resistant houses. However, evidences show that so many pre-code houses exist and the public awareness of potential losses during earthquakes is low. Better understanding on seismic behavior of the building is indispensable. One of the solutions is to encourage public awareness for strengthening of their own houses by letting them know how their town shakes during an earthquake and what happens in his/her house.
In this research, we proposed the earthquake disaster mitigation strategy based on the seismic simulation of structures during an earthquake.
As the amount of total buildings in a city is huge, statistic approaches are commonly employed. Therefore, results of estimation obtained are in average and might not be sufficient in convincing the public. On utilizing 3D GIS data, this study provides a method of constructing structural models of large amount of buildings, which enables seismic analysis of building structures. Evacuation behavior under emergency situation also can be simulated.
To reduce the casualty due to earthquakes, it is very important to know the process structures collapse and how the occupants get injured. Three dimensional behavior of the collapse of timber frame houses under seismic motion were analyzed by using Distinct Element Method (Fig. 3). Outputs can be used as a useful tool of risk communication. These contents are open to the public and can be downloaded through web-site
