Thermal Analysis of Fire Door Subjected to a Fire Test

In this paper the thermal analysis of fire doors for naval application is investigated. To evaluating their behavior, fire doors are subjected to standard fire tests by means of a customized furnace, where the temperature changes according the current regulations. A finite element model is developed with the aim of capturing the behavior of the fire door and then results obtained from non-linear transient and static analysis are compared. Also, to further validate the accuracy, the proposed model is compared with experimental results obtained during standard fire tests. Images obtained by thermo-graphic camera and outputs from thermocouples confirm that the adopted analysis is good enough to properly describe the thermal behavior of the door.
