Current floor systems of Australian low‐rise steel residential houses and buildings consist of cold‐formed light‐gauge steel floor joists and mainly sheet flooring (particleboard). There are potentially some issues including uncomfortable floor vibration and noise, which could annoy the occupants. In Australia, there are several different types of steel floor systems as well as timber systems. Few research on structural performance of Australian floor systems including flooring materials in terms of vibration has been carried out and reported. This paper describes present Australian common steel and timber floor systems and their structural characteristics obtained by static and dynamic loading tests with regard to human comfort. Additionally, a new hybrid AAC flooring system with steel frames is proposed and tested compared with common sheet flooring. It is found that AAC panels connected to the particleboards can greatly improve human comfort but not fundamental frequency.
