2306.1.1 Joists and Rafters
The design of rafter spans is permitted to be in accordance with the AWC STJR.
2306.1.2 Plank and Beam Flooring
The design of plank and beam flooring is permitted to be in accordance with the AWC Wood Construction Data No. 4.
2306.1.3 Treated Wood Stress Adjustments
The allowable unit stresses for preservative-treated wood need not be adjusted for treatment, but are subject to other adjustments.
The allowable unit stresses for fire-retardant-treated wood, including fastener values, shall be developed from an approved method of investigation that considers the effects of anticipated temperature and humidity to which the fire-retardant-treated wood will be subjected, the type of treatment and the redrying process. Other adjustments are applicable except that the impact load duration shall not apply.
2306.1.4 Lumber Decking
The capacity of lumber decking arranged according to the patterns described in Section 2304.9.2 shall be the lesser of the capacities determined for moment and deflection according to the formulas in Table 2306.1.4.
