| Abstract: | The concept of performance based fire safety design is becoming increasingly popular and often supplements designs based on prescriptive codes. Under performance based concept, specifically defined fire safety goals are set and analysis is carried out to identify the design that achieve these goals in most efficient and cost effective manner. Simply put, performance based design implies use of fire safety engineering for design purposes. During last two decades, two different approaches to fire modelling have emerged, known as zone and field modelling. In the present paper, two case studies have been presented, one involving a zone model and other involving CFD model for simulating fire environment inside two different types of building enclosures_an assembly hall and a long corridor. Attempts have been made to predict untenability conditions and calculate ‘Available Safe Egress Time (ASET)’ values. These calculations are essential for carrying out performance based fire safety design analysis for a fire scenario involving safety of occupants. The first case study pertains to simulation of a fire inside a hall using CFAST _a multi room zone model. The second case study pertains to simulation of a fire inside a long corridor using CFX._a CFD modelling technique. |
