Modeling Different Modes of Post-Earthquake Fire Spread

Abstract eng:
In this paper, a physics-based post-earthquake fire spread model that is under development is introduced. The model includes several key modules, representing the primary modes of urban fire spread: (1) evolution of fire within a room or roof; (2) room-to-room spread within a building through doorways to adjacent rooms, by burn-through to adjacent rooms or a room or roof above, or by leapfrogging through windows to a room above; and (3) building-to-building spread by flame impingement and radiation from window flames, radiation from room gas, radiation from roof flames, and branding. Each of these modes of spread is described in turn, including a discussion of how it has been modeled in the past, and the approach taken in the new simulation.
