Experimental and numerical approach to fire-resistance of floor structure of rolling stock

초록

To secure the safety of the rolling stock the fire-resistance for the structures should be considered. The floor structure of the rolling stock should withstand the weight of electronic units such as motors, transformers and etc. as well as interior materials and passengers. Korea and other countries has the regulation for the fire-resistance of the floor structure of the rolling stock.[1,2] In this study, the fire-resistance of the floor structures for rolling stocks with two types of insulation materials are compared by using the experimental and numerical approaches. The floor structure consists of the flooring cover, foamed aluminum alloy panel, insulation and extruded aluminum alloy main structure as shown Fig. 1.
