Outline of Final Research Achievements

This study analyzes the applicability of paragraph 3, article 42 of the Building Standard Law for the preservation of historic alleys. Reduced scale experiments on heat transfer within an alley in case of fire and temperature-rise under an eave were conducted in order to investigate the behavior of fire spread between buildings. For the improvement of the fire spread simulation, critical condition for fire spread from a fire room to adjacent room was investigated by a compartment fire experiment. As for the fire risk assessment, questionnaire survey for post-earthquake ignition following the Tohoku earthquake was conducted and a probabilistic model was developed. Requirement of the present regulation was analyzed from the perspective of fire spread risk and evacuation safety. Survey on construction type was conducted in Kyoto city and a model for estimating the ratio of buildings unqualified to the present regulation is developed with additional statistical data on houses and land use.
