About this detail

A wide flange steel column is encased within a concrete shear wall, incorporating Grade 80 number 5 stirrups spaced at 4 inches on center and number 9 vertical reinforcing bars hooked into the foundation grid. Three-quarter-inch diameter by 3-inch headed studs are welded at 8 inches vertical spacing typically along the steel section. Continuity plates measuring 1 and 3/4-inch minimum thickness are welded with 5/16-inch complete joint penetration welds at the web and flanges, with plate thickness increased where diaphragm bars align with beam face stiffener plates to accommodate rebar couplers. Diaphragm reinforcement ties into the assembly per plan using welded couplers, and beam face framing members are provided per elevations.
