ABSTRACT=Many studies and observations of large building fires show that in large compartments, fires do not burn uniformly. Rather, fires will burn locally and move across a floor plate as fuel is con-sumed. Currently fire engineering practice assumes uniformly burning fires within a compart-ment and the fire design methodologies are based upon small compartment fire scenarios. Trav-eling fire modeling that accounts for fire dynamics is essential for performance-based fire engi-neering. This paper reviews two traveling fire models presented in literature and implements both models on a steel-frame building. An advanced analysis of the building is performed and the fire performance of the building in these travel fire scenarios are compared to the fire perfor-mance of the building when subjected to conventional fire exposure scenarios (full story fires or compartment fires). The authors then illustrate the use of structural fire engineering methodolo-gies to improve the fire resistance of the building.
