Section 562(1) Reductions in allowable loads required therein for high moisture conditionof the lumber and service conditions do not apply.(2) Use 75 percent of the tabulated design value as the design value ofbolts in two member connections (single shear).(b) Steel. For identified grades of steel, do not exceed the design stresses(other than stresses due to flexural compression) specified in the Manual ofSteel Construction as published by the AISC.When the grade of steel cannot be positively identified, do not exceed thedesign stresses, other than stresses due to flexural compression, either specifiedin the AISC Manual for ASTM A 36 steel or the following:Tension, axial and flexural = 22,000 pounds per square inchCompression, axial = 16,000 - 0.38(L/r)² pounds per square inchNote: L/r shall not exceed 120.Shear on the web gross section of rolled shapes = 14,500 psiWeb crippling for rolled shapes = 27,000 pounds per square inchFor all grades of steel, do not exceed the following design stresses anddeflection:12,000,000Compression, flexural (1) =pounds per square inchLd/btNote: (1) Not to exceed 22,000 psi for unidentified steel or steel conforming toASTM A 36. Not to exceed 0.6 F y for other identified steel.Where:L = Unsupported length.d = Least dimension of a square or rectangular column or thewidth of a square of equivalent cross-sectional area for roundcolumns or the depth of beams.b = Width of the compression flange.t = Thickness of the compression flange.r = Radius of gyration of the member.F y = Specified minimum yield stress for the grade of steel used.481
