Metal web engineered timber joists are increasingly being used nowadays to replace traditional solid timber joists for constructing intermediate-span timber floors in low-rise houses and long-span floors in commercial buildings. Vibrational performance criteria become crucial for serviceability design of timber floors and often control the design. This paper presents an experimental study carried out on the dynamic performance of a series of full-scale floors constructed with metal-web joists with focus on modal frequencies, modal shapes and damping. The effects of a range of floor component configurations including spacing of joists, type, size, number and location of strongback, ceiling, etc., were examined.
