"This report describes the construction of, and static and dynamic tests performed on, a 3.6 x 3.6 m "low profile" floor system. The timber framing system comprised 200 x 35 mm x F8 bearers connected planar with 200 mm deep, double plyweb beams as joists. The walking surface of the floor was sheathed with 13 mm thick structural plywood glue/nailed to the bearers and joists. The two adjacent edge joists were at 360 mm centres with the internal joists at 480 mm centres. The underside of the floor was lined with 10 mm gyprock connected "in-situ" after the "plywood sheathed only" construction had been subjected to a full range of tests. The new construction was then subjected to the identical set of static and dynamic tests. A further dynamic test involving determination of the resonant frequency with the floor subjected to 1/3 of the live load was also performed."--p. (ii).
