Design Parameters

AISC 358 / AISC 341 seismic design

Mpr = CprRyFyZe at the plastic hinge and Mf = Mpr + VhSh at the column face are added as a load case; the prequalification limits, continuity plates, panel zone (J10-11, φ = 1.0) and the column-beam moment ratio are checked.

Used in Zx, Ix and T; not in the catalogue.

AISC Shapes Database v16.0.

T-stubs (cut from a rolled W-shape)

Conventional single-plate shear connection welded to the column flange (Manual Part 10): bolt group at e = a/2, plate shear / block shear, two-sided fillets.

Design Guide 13: the stiffeners carry Ru,st = Pf - φRn,min; the doubler adds 0.6Fydctdp to the panel zone.
