Implementation of a New Design Travelling Fire Model for Global Structural Analysis

Abstract

This paper presents a new conceptual framework for travelling fires in large compartments with fire resistant islands in order to ensure that the structure so designed is able to resist more realistic fire exposures expected in such compartments, commonly found in modern office buildings. In addition, this paper also presents the implementation of this new travelling fire model in the SIFBuilder framework [1], which is an OpenSees based integrated computational tool for performing automated thermo-mechanical analyses for large structures subjected to a broad range of idealised design fires.
