Abstract
The amount of flammable
materials in traditional Japanese houses in the Hiroshima region
in the 1940s is estimated to calculate heat, water and carbon fluxes
during the induced urban fire by the Hiroshima A-bomb in 1945. Traditional
houses remaining in the Fukuyama region were examined to estimate
the total amount of flammable resources in each house classified
into three categories based on number of stories and size of the
houses. Our research revealed that the kind of flammable resources
is mostly pine and the density of wood was estimated to be 112 kg
m-2 for one-story houses while it was 72 kg m-2 for two-story houses.
