Abstract

<p>Recently, it is advocated to introduce the idea of the performance based codes into fire zoning. As for the urban safety level of quasi-fire-zone where a great deal of damage of post-earthquake fire is expected, it is very important to discuss the safety level of post-earthquake fire from performance specifications point of view. In this paper, the authors developed the simulation model for people's wide area evacuation in case of post-earthquake fire, and conducted estimation of suffred number of evacuee who lost their way to escape from the fires. Applying the model to urban improvement, the authors discussed the desirable safety level of fire spread speed and fire breakout probability from acceptable suffered risk of wide area evacuation point of view.</p>
