Evolution of fire models for estimating structural fire-resistance

Many fire models have been proposed to investigate structural response fire, where is considered as a “load” and the determines “resistance” offered by structure. Where term used with its physical meaning not restrained standard application. Over course of time, evolved from simply using highest gas temperatures resulting fully developed compartment more sophisticated computational fluid dynamics (CFD) models, hyper-realistic time-varying can be determined for range realistic scenarios. This paper examines current state art in terms defining analysis. Widely adopted analysis are therefore reviewed. discusses limitations scope applicability most commonly models. Recent developments on coupling CFD FEM also discussed detail their practical scenarios explored. The primary concern this review evaluate suitability while assessment studies manner which actual done. • Review widely quantify resistance. methods determine fuel load.
