Bending Strength & Stiffness for Structural 1 (15.1mm) Panel and Support Spacing ‘Roof-40’
| General info: | Structural 1 indicates a performance-rated panel, with superior bending stiffness and strength |
| Bending strength – stress applied parallel: | Factor of safety (F S) – 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) – 405 (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 – 89,600 when stress applied perpendicular to strength axis |
| Span rating/support spacing: | Roof-40 |
| Thickness/US Performance Category*: | 15.1mm (min 14.3mm; max 15.85mm); (19/32)* |
