6 REFERENCE STRENGTHS3.1 GeneralThe tables in this chapter provide LRFD referencestrengths for design of structural lumber members. Thesestrengths are used when manual calculation of memberstrength is required, and shall be used in conjunction withthe adjustment factors specified in Chapter 4.The tables follow the same format as the allowablestress design National Design Specification ® for WoodConstruction (NDS ® , 1991).3.2 Tables of Reference StrengthsThe tables of reference strengths are similar to thetables in the 1991 NDS Supplement, with referencestrengths being factored per ASTM D5457-93 and valuesexpressed in ksi (kips per square inch). Table 3.1 (mechanicallygraded lumber) corresponds to NDS table 4C.Table 3.2 (visually graded dimension lumber) correspondsto NDS Tables 4A and 4B. Table 3.3 (visually gradedtimbers) corresponds to NDS Table 4D. Table 3.4 (bearingdesign values) corresponds to NDS Table 2A. Table3.5 (decking design values) corresponds to NDS Table4E.Note that the adjustment factors to be used with thesetables are identical for all tables with the exception of theapplication of the size factor (see footnotes to Table 4.3).
