Another approximation for spatial separation

A simple, accurate and fail-safe method is given for calculating the separations between buildings that would be sufficient to prevent spread of fire by radiation. The new method makes tables unnecessary for this purpose, and avoids the errors of the "gray radiator" method, which are explained. The article is primarily intended to assist those who wish to simplify building codes, but the theoretical basis is also stated.L'article donne une m\ue9thode simple, pr\ue9cise et s\ufbre de calculer l'espacement entre des b\ue2timents suffisant pour pr\ue9 venir la propagation du feu par rayonnement. La nouvelle m\ue9 thode permet de se dispenser des tables et \ue9viter les erreurs de la m\ue9thode dite du "gray radiator". L'article est destin\ue9 principalement \ue0 aider ceux qui d\ue9sirent simplifier les codes de b\ue2timent, mais la base th\ue9orique de la m\ue9thode est aussi expliqu\ue9e.Peer reviewed: NoNRC publication: Ye
