火災および建物統計情報を用いた出火リスクの類型化の試み: 統計データに基づく火災リスク評価手法に関する基礎的研究 その1

摘要

火災の件数は火災報告より，建物ストック情報は法人建物調査より得て，建物の構造および建物用途に応じた規模別の出火率の算出を試みて，以下の結論を得た。①大局的には国内外の先行検討例に似て，同一のカテゴリー内での出火率は建物規模が大きくなるほどに低下する傾向が支配的である。%The paper is intended to find out the effect of building size on the frequency of fire starting for a variety of building use types: 1. Corporate Survey of Buildings is a useful source of information on non-residential commercial building stock in Japan. 2. Fire statistics data can be used to estimate the distribution of the size of buildings within which fire started for a certain period of time, while the size distribution of the buildings at risk in Japan can be derived from Corporate Survey of Buildings for specific building use types. 3. Ignition frequency of typical building uses in Japan was found to depend heavily on the size of the building, i.e. total floor area of the building.
