Numerical Evaluations of Fire Resistance of Railcar Floor

Fire resistance of a floor of a railcar is prescribed in the "Guidelines of standard of railcar safety (Minister of Land, Transport and Maritime Affairs, 2010)". A floor of a railcar should retain its fire resistance for 15 or 20 minutes according its risk level. To evaluate fire resistance of the floor materials which are composed of ceramic board or aluminum foam with weight lightening, fire resistance of railcar floor is numerically analyzed.
