Span values are in metres
Loading Data:
Dead Load of roof and ceiling maximum 90 kg/m2 for tiled roofs, and 40kg/m2 for sheet roofs.
(Covers standard up to terra-cotta roof tiles, plasterboard ceiling below, roof trusses or raftered roof)
Roof Live Load of 0.25kPa.
Wind design for up to N3 wind area, in accordance with AS4055-2006 – Wind Loads for Housing.
ETH LAM GL 17 beams are manufactured straight, without any camber built into the beams.
Lintel design criteria in accordance with methods presented in AS1684.1-1999, and structural timber design in accordance with AS1720.1-2010.
All lintels are designed for single span only.
Notes:
- Minimum bearing lengths for support of lintels: 35mm on trimmer studs. Size and width of trimmer and jamb studs is subject to loadings outside the scope of this table.
- The span value shown is the distance between centrelines of supports.
- Deflection criteria: for permanent load combinations, the lesser of Span/300, or 10mm, and for Roof Live Loads, the lesser of Span/250, or 15mm.
- For lintels the lateral restraint is assumed to be a maximum of 600mm.
- Where there are conflicts in design between loading codes (AS/NZS1170 series), timber code (AS1720.1-2010) and AS1684.1-1999, the loading codes and timber code take preference.
- Maximum roof pitch applicable for these tables, 25 degrees.
