For custom sections of lumber beams from the Beam and Stringer classification listed in O86 Table 5.3.1.C , the fb, ft, fc, and E values shown in the Factors table of the Additional Data were the ones for the Post and Timber grades from Table 5.3.1.D. However, the resulting resistances (Mr, Vr, Pr) shown in the Force vs. Resistance table were derived from the correct Post and Timber strengths, and these were the values used for design. This was therefore a display issue only, and has been corrected.
