Abstract: In order to optimize the design and development of extra-large fire doors, a double-leaf steel fire door with dimensions of 4 600 mm (width) × 5 000 mm (height) was designed and manufactured. Fire resistance tests were conducted, and the finite element method was applied to perform steady-state and transient thermal analysis of the extra-large fire door. The fire resistance performance was characterized by measuring the temperature on the backfire side, verifying the effectiveness of the finite element method in fire door design.

Key words: extra-large fire door, fire resistance performance, FEM, thermal analysis
