Design Parameters

Load cases (major-axis moment hogging at the splice; 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 end plate.

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

Both beams are the same section; the two end plates are identical.

AISC Shapes Database v16.0.

The bolt rows and the extension stiffener follow from the configuration; AISC 358 prequalifies these three for SMF / IMF (seismic option on the General tab).

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.
