Design Parameters

Load cases (major-axis moment hogging at the column face; axial + compression / - tension)

NameMoment (kNm)Shear (kN)Axial (kN)

LRFD: factored loads (Mu, Vu, Tu); ASD: service-level combinations (Ma, Va, Ta). The moment is the design moment at the face of the column.

Not in the catalogue - enter it from the section tables. 0 ignores the root fillets (conservative: smaller plastic modulus).

AISC Shapes Database v16.0.

kc = tcf + r for web yielding / crippling; not in the catalogue - 0 is conservative.

The beam is bolted to the column flange (major axis). ASTM A992 (W), A572 Gr 50, A36 (AISC Manual Table 2-4); bolts ASTM F3125 Grades A325 / A490.

The bolt rows follow from the configuration.

The bottom of the plate mirrors the top (moment reversal); the bolts below the compression flange carry the vertical shear.

For CJP flange welds enter the reinforcing fillet (it enters lb of the column web checks); 0 = none.
