About this detail

A continuous structural angle sized as L4x4x1/4 is anchored to a concrete wall or beam using three-eighths-inch thick by five-inch wide by zero-foot-eight-inch long plates spaced at three feet on center, with a minimum of two plates per section of angle. Two three-quarters-inch diameter by six-inch long headed shear studs spaced at five inches on center are welded to the angle flange to anchor into the slab on deck. A steel beam frames into the wall connection, utilizing welded attachments with four-inch fillet welds typically applied. Diaphragm reinforcing bars including number four bars at eighteen inches on center run parallel to the core, with hooked bars provided where wall thickness is less than development length plus required cover. A cast-in-place option detail indicates welded wire reinforcement or reinforcing per framing plans, with deck attachment executed per general notes.
