Study on evaluation and application method for urban improvement program in congested wooden building zone through the spread of fire

Abstract

After the Great Hanshin-Awaji Earthquake Disaster, the fire spreading risk in congested wooden building zone has been widely recognized. There was no simple index, however, to evaluate the fire spreading risk and the effect of urban improvment program toward fireproof zone. This paper aimed to introduce two indexes of "Fire-proof Index" and "Average Distance between Buildings" for the evaluation. These two indexes were chosen in reference of the fireproofing projects in Tokyo. The actual values of the indexes were measured on the Geographic Information System of Tokyo. Then multiple regression analysis was applied to evaluate the indexes using the fire spreading simulation system.
