Note that all effects are for single joists. Double and triple joists are considered by NJ. Nothing else.
Thus the multiple joists need not be fastenned together as their responses are considered to be
independent. In reality, joists which are fastenned together at regular intervals would respond
in between independent joists and a single joist of thickness the sum of the joists thicknesses;

Joists that bear directly on the walls must not project into the cavity since this encourages fire
spread and also subjects joists to moisture. Ends of joists should be treated with preservativeagainst possible decay due to moisture penetration. There may be a steel wall plate 75 x 6mm
to spread load of joists. The bricks are built around the joists and since the joists depth(notched or otherwise) is to be smaller than brick depth, the brick does not bear onto the joists.
Max joist spacing 1.2m.

Strutting is used to provide lateral torsional buckling restraint. Strutting is also used to
maintain the timber joists in the vertical position. Also, new timber is often not as wellseasoned as it should be and as the timbers dry out they tend to shrink and lose shape (joists
may twist) unless restrained with strutting.
Strutting should be employed at supports and at certain intermediate span locationsdepending on the span.

Floor boards are laid across the floor joists and cramped together (along edges parallel to the
span of the boards, i.e. perpendicular to span of joists) with the tongued and grooved (T&G)joints. The boards, as they are cramped up, are nailed to the joists with two nails to each board
bearing on each joists.
The joint at the end of each board in its length is called the heading joint. The heading joints infloor boards should always be staggered in some regular manner. Obviously, the heading joint
ends of boards must be cut so that the ends of both boards meet and rest on a joist (since theboards span between joists) to which the ends are nailed.
Floor boards width: 65, 90, 113 or 137mm;
Floor boards thickness (and max spans): 16 (505mm), 19(600mm), 21(635mm) or 28mm(790mm);

plasterboard, which also acts as a fire protection.

Pugging can be used to increase mass and hence reduce airborne sound. This involves
spreading a layer of plaster or sand on rough boarding fixed between joists on battens or onexpanded metal lath and plaster. Pugging does not decrease impact sound.
Impact sound can be reduced by laying carpet or some resilient material between the
floorboards and joists, draped over the joists. Alternatively a floating floor, known as aplatform floor can be employed. This is a 18mm thick T&G board or chipboard (with all joints
glued) spot bonded to a base of 19mm thick plasterboard, then laid on a 25mm thick resilientmineral fibre on a floor base of 12mm thick boarding or chipboard nailed to the joists. The
ceiling comprises two layers of plasterboard, with joints staggered, to a finished thickness of30mm on which 100mm of absorbent mineral fibre is laid.
To limit flanking transmission of sound from the floor surface to the surrounding walls, a stripof resilient fibre material is fixed between the edges of platform, floors and surrounding solid
walls and a gap of 3mm is left between the skirting and floating floors.

sometimes 600mm high. Sleeper walls are built honeycombed to allow free circulation of air
below the floor. The end sleeper wall is built 50mm from the internal or external load bearingwalls and carries the end of the joists. This gap allows air to circulate. Under floor ventilation
should have a free path between opposite sides, with openings equivalent to 1500mm2 for eachmetre run of wall.
Concrete floor slab thickness for suspended timber ground floors for domestic purposes
commonly 100mm. Alternatively, concrete floor slab thickness of 50mm on a DPM of 1200gauge polythene on a bed that will not damage it.
Suspended timber floors require thermal insulation. Rolls or quilt of loosely felted glass fibre or
mineral wool can be supported by a mesh of plastic that is draped over the joists and stapled inposition. Alternatively, semi-rigid slabs or batts of fibreglass or meneral wool can be supported
between joists by nails or battens of wood nailed to the sides of the joists.
