I’m designing an embedment to transfer moment Mu and shear Vu from a steel wide flange beam to a concrete column (as shown in the schematic). My design assumptions: • The plate remains elastic and deformations are negligible; • All studs are the same type, size, and depth; • Stud tension reactions T1 and T2 are proportional to the distance from the toe of the beam compression flange; • The tension reactions are equilibrated by a concrete reaction C centered on the beam compression flange; • The concrete is cracked; and • The column reinforcement will provide supplemental reinforcement for the anchorage. When checking the moment capacity, should I use the maximum stud tension reaction T1 to check the concrete failure area for the headed stud anchors? When checking the shear capacity, should I assume that the concrete pryout strength Vcpg is for Rows 1 and 2 only or for all four rows?
