Abstract:

Highlights•Full-scale experimental data of atrium fire tests.•Assessment of stair stepping on the smoke layer and temperature field.•Validation of CFD numerical model FDS.•Numerical study for different area-to-height-squared ratio atria.•Good agreement between experiments and numerical simulations, especially far away from the fire source and the centerline.
