Residential Buildings With Numerical Modeling

Abstract
This study is intended to present a computational standard model for
combustibles, compartments and buildings. As performance based design is
more popular, fire-intensity and fire-load have turned out to be very important
factors for building design and can be predicted through some computational
work. To predict and estimate the fire properties of a residential fire, we made
some numerical models of combustibles, compartments and a residential
building. In a bid to validate the estimate values, research was divided into three
parts of step verifications. The first was for combustibles, the second was for
compartments and the third was for the building. During each step,
computational analysis results from numerical models were compared with real
fire tests. For computational analysis, the Fire Dynamics Simulator was used
with Large Eddy Simulation model for turbulence. Consequently, fire-intensity
was well predicted and flash-over of rooms were successfully estimated.
Keywords: combustible, compartment, real scale fire test, numerical analysis,
fluid dynamics simulator.
1 Introduction
In line with increasingly popularized performance based design (PBD), the need
of numerical analysis of building fires used to collect the data required for
building design has been on the rise. Predicting fire growth and smoke spread
pattern enables us to allow safe evacuation and analyze the caloric value. Radiant
heat enables us to predict the potential damage to the structural member by fire
heat. In addition, calculating the amount of toxic gas enables us to predict the
level of exposure to toxic gas the people inside, to thereby providing data needed
