Common studs

Common studs are vertical members which transfer loads vertically to bottom plates.

They are usually evenly spaced to suit loads, lining and cladding fixing. Spacings are generally 450 or 600 mm, depending on the roof cladding. Roof tiles require studs at 450 mm spacing. Metal roofing may require studs at 600 mm.

Common studs should be reinforced at points of concentrated loads. This is done by nail laminating additional studs together.

All junctions must have sufficient studs. They must be located so as to allow linings to be fixed.

Four diagrams from the Timber Promotion Council's Timber Framing Manual (revised February 1994). The first two show two different ways of framing intersections. One way is to place a stud between two existing studs. In this case three noggings are spaced evenly along the height of the stud. The second shows three studs used. These are to be securely fixed with blocking and nails. Special fixing may be required for internal linings.<br/>The last two diagrams show framing for corners. In the first of these, three studs are securely fixed with blocking and nails. The other diagram, which is suitable for external brick veneer walls, two studs are used, and three long stud size blocks 200 mm long are required, spaced equally. Studs are to be securely fixed with blocking and nails.
