For design information including span tables Download Verandah Flooring Solutions Using LYSAGHT FIRMLOK® (116 KB). This covers non-cantlevered veandahs and uses 3kPa live loading suitable for use in areas with wind classifications up to and including N3 (W41N).

Design Data

Live loads of 3 kPa have been used to calculate spans. Live point loads must be transferred to the LYSAGHT UNI-PIER® and not to the LYSAGHT QUIKA-FLOOR®.

• Dead loads for the design of floor members = 0.5 kPa.
• Dead load of sheet roof = 0.4 kPa
• Dead load of tile roof = 0.9 kPa
• Wind rating N3 (W41N permissible, W50N limit state)

Terminology

Bearer: A section supported by walls, piers or stumps, which in turn supports floor joists, floors and walls.

Floor Joists: Sections spaced at a maximum of 450mm, that span over walls or bearers to which flooring is fixed.

Floor Load Width: The width of verandah floor supported by each bearer or support.

Joist Spacing: Centre-to-centre distance between floor joists.

Sheet Roof: Includes roof clad with continuous sheets of steel, aluminium, fibreglass, polycarbonate or metal tiles.

Tile Roof: Includes roof clad with concrete or terracotta tiles.

Roof Load Width: The width of verandah roof supported by each bearer or support.
