Abstract

Fire dynamic characteristics in multi-compartments are still not very clear. This paper presents a spreading fire test in a full-scale two-storey steel framed building to investigate the multi-compartment fire behavior. In the test program, the fuel was made by a total of 6.8 m3 discrete pine cribs and then ignited at one compartment. The spatial temperature and steel member temperature histories were recorded throughout the fire test. FDS model was then established and compared with the fire experiment results. Reasonable agreement between experimental and numerical results was achieved at the fire growth stage and spreading stage. Based on test results, it was observed that flames spread to the fire-spreading compartment in 82 min after fire when the fire in the fire-source compartment fully developed, which caused multiple temperature peaks and significant temperature gradients. The experiment revealed the possibility and characteristics of fire spread among multi-compartments. It also verified the invalidity of the homogeneous temperature assumption and provided important data for performance-based structural fire design in multi-compartment spreading fire scenarios.
