Rated Sheathing 15.1mm Panel: Bending Strength & Stiffness with Support Spacing ‘Roof-40’
General info: | APA Rated OSB Sheathing always has a bond durability classification of Exposure 1 as not for exterior use. Panels have one surface with an overlay, texturing or grooving. Creating the tongue reduces the panel width by approximately 12.5 mm (1/2 in), so net width may be 1,206mm (47.5 in) |
Bending strength – stress applied parallel: | Factor of safety (F S) bending strength –750 (lb-in²/ft of panel width) when stress applied parallel to strength axis. The strength axis is always parallel to the face and back orientation of the strands unless otherwise indicated |
Bending strength – stress applied perpendicular: | Factor of safety (F S) bending strength – 270 (lb-in²/ft of panel width) when stress applied perpendicular to strength axis |
Bending stiffness – stress applied parallel: | E I (lb-in²/ft of panel width) – 225,000 when stress applied parallel to strength axis. E I provides a measure of the resistance of the beam to bending. The larger the E I, the smaller the deflection |
Bending stiffness – stress applied perpendicular: | E I – 56,000 when stress applied perpendicular to strength axis |
Span rating/support spacing: | Roof-40 |
Thickness/US Performance Category*: | 15.1mm (min 14.3mm; max 15.84mm); (19/32)* |
