18.5 mm, 7 ply Doug Fir Plywood (Bug 2629)

In generating the allowable C&C loading on of horizontal Douglas-fir plywood 18.5 mm x 7 plies, an bending strength m_p’ value of 100 n/mm/mm was used, instead of the correct 1100 from Table 7.3A, 0° orientation. The bending strength was correspondingly 11 times lower than it should be, and the allowable loads 7-11 times lower depending on stud spacing.

9.5 mm 2R24 OSB (Bug 2631)

The allowable C&C load for 9.5 mm 2R24 OSB sheathing was 7.4 when it should have been 7.94. This has been corrected.
